The DTP News and Views blog is Brian Fitzpatrick's (aka "Fitz") window on the world. Here you'll find information about what DTP is up to, articles on using DTP better, and how folks in the community are using DTP around the Eclipse-a-verse.
We had eight people total complete the survey (a big thank you to all of you), which was more than I was expecting honestly. With as quiet as things have been in DTP lately, I was expecting the sound of crickets to be prevalent. :)
However... As promised, here are the final survey results...
Question 1: Where do you use DTP?
a) Standalone in Eclipse for the database functionality (green)
b) Within WTP or Dali (JPA) (red)
c) Within a commercial product from IBM, Oracle, Sybase, or other company (yellow)
d) Other (please specify) (blue)
As I said in my last post, this was a bit surprising to me. I had no idea that this many folks actually used DTP for its standalone database functionality rather than as part of a larger suite.
The responses to "Other" included:
As part of our tool. For reading database meta data and for parsing SQL (planned).
BIRT
I'm not sure how I forgot BIRT - it wasn't deliberate. But it's nice to confirm that DTP is in fact being used in a few different contexts.
2. How do you use DTP?
a. As a user
b. As a developer
Definitely more use of the DTP toolset for developers than users, but it's nice to see users represented in there as well.
Question 3: Where would you like to see DTP used?
This was an open-ended question and we ended up with three replies:
As a replacement for SQuirreL SQL inside Eclipse.
As more integrated with the IDE
Or as a standalone RCP SQL Tool like PL/SQL Developer
Question 4: What functionality would you like to see in DTP? Or what changes would you like to see?
This was another open-ended question with more responses:
Provide documentation about what is supported for each database... e.g. "how do I see an SQL query explain for Sybase ASE or DB2 UDB"?. After hours of experimenting I *think* its not possible but can't tell for sure.
Offer the ability to specify an order when executing a batch of sql files
ETL functionality - data extract and load
Easier handling - see PL/SQL Developer! More DB-Status functions
Improve the SQL parser as a standalone library
Each of these will probably find their way into Bugzilla as feature requests. And though not all will likely get done, it's good fodder for discussions going forward.
Question 5. Would you like to help with DTP?
There were only three responses - yes, no, and other. The other described itself as "willing to report bugs and test cases", which is great. "No" isn't helpful, but is understood due to a lack of time or resources. And "Yes" is what we always like to hear!
All in all, I'm pleased with the results. We received some constructive feedback in addition to simply discovering that our community still has a heartbeat. :)
As I said last time... If *YOU* have more suggestions for us, feel free to join the mailing list (dtp-dev@eclipse.org) or put a message on the forum/newsgroup and let us know what you're thinking. As always, we're looking for help - whether it's testing and reporting bugs, contributing patches, or becoming a committer!
Thanks again to everyone who filled out the survey. It helps to know what you are thinking!
Well, I'm happy to report that not only are there people willing to respond to my survey, but they're willing to respond to a survey about DTP! So it's good to know that there are a few people out there who are still alive and kicking in the community. :)
After a week, we've had 7 responders. No, it's not a huge number, but it's honestly better than I was expecting. And we've had some interesting responses...
The answers to the first question about where our users actually use DTP was shocking to me. I had no idea that this many folks actually used DTP for its standalone database functionality rather than as part of a larger suite.
For the second question, overwhelmingly nearly everybody who uses DTP seems to use it more as a developer than as a user.
Some of the responses as to where folks would like to see DTP get used were also interesting:
As a replacement for SQuirreL SQL inside Eclipse.
As more integrated with the IDE
Or as a standalone RCP SQL Tool like PL/SQL Developer
We used to hear a lot about the SQuirreL SQL angle in the beginning of DTP, but I hadn't heard that mentioned for a while. Sounds like the PL/SQL Developer is a similar request for functionality, but perhaps as a RCP application. We actually started a bit of this effort in the last release that's available in CVS (look in the Enablement project for the org.eclipse.datatools.enablement.rcp plug-in - it's rough, but it's a start).
And then we had some very thought provoking requests for new functionality...
Provide documentation about what is supported for each database... e.g. "how do I see an SQL query explain for Sybase ASE or DB2 UDB"?. After hours of experimenting I *think* its not possible but can't tell for sure.
Offer the ability to specify an order when executing a batch of sql files
ETL functionality - data extract and load
Easier handling - see PL/SQL Developer! More DB-Status functions
Improve the SQL parser as a standalone library
I'm not quite sure what we'd do for #1 or #4, the rest are pretty self-explanatory. Though we'd love to have any/all of these entered as feature requests in Bugzilla, it's great feedback. We *LOVE* feedback.
Do *YOU* have more suggestions for us? Well, if you haven't already filled out the survey, go ahead and fill it out now (click here for the survey). If you've already filled out the survey, feel free to join the mailing list (dtp-dev@eclipse.org) or put a message on the forum/newsgroup and let us know what you're thinking.
And as always, we're looking for help - whether it's testing and reporting bugs, contributing patches, or becoming a committer!
Thanks to everyone who's filled out the survey so far and thanks in advance to anyone else who does the same!
As we start looking at what will go into DTP (Data Tools Platform) 1.9 for the Eclipse Indigo (June 2011) release, it struck me that we don't know that much about how DTP is being used currently. It's been a while since we "polled the studio audience" to see what was up...
And though we have a skeleton crew now helping us with bug fixes and new features, we'd love to have more folks pitch in to help - whether it's by writing articles or blog posts, reporting bugs, or offering to lend a hand with patches for existing issues or new functionality. However the help is offered, we'll probably consider it!
But we'd love it if you use DTP if you could take some time and please answer a few survey questions:
But I saw a demo this morning for some new functionality coming to JBoss Tools by the end of the year that uses DTP connection profiles and several views!
Teiid Designer provides tooling for the Teiid server, which has all kinds of cool functionality. As they say in the Teiid site - "Teiid is comprised of tools, components and services for creating and executing bi-directional data services. Through abstraction and federation, data is accessed and integrated in real-time across distributed data sources without copying or otherwise moving data from its system of record."
In the demo I saw this morning, I saw two disparate data sources - one Oracle, one SQL Server I think - that were then abstracted via a virtual database that could then access both. So this is sort of like ODA in BIRT, which combines data from different sources to create a particular report. But unlike BIRT which is largely a one way funnel of information to the report engine from what I understand, Teiid provides bi-directional support so you can use this abstraction to go back and forth between data sources.
Long story short, I am encouraged by the fact that - without much help from those of us left in DTP - the Teiid tooling guys managed to adopt the connection profile frameworks and reuse a good amount of tooling for their own stuff which had been on their own proprietary technology.
So a big congratulations to the Teiid guys for their work integrating DTP into their tools. :) As soon as our new milestone release of JBT goes live, I'll provide a link to their "New and Noteworthy" page so you can see some screen shots and more about what this cool tool does.
Hopefully we can see more of this kind of integration with DTP and Eclipse and possibly gain some more folks to help keep DTP alive for the future!
I'll try not to let my next post be another 5 months from now... Geez.
After the "Future of Open Source" panel at EclipseCon 2010, I've been pondering one of the comments about how open source doesn't do "pretty" well. And I have to admit. We have some issues there. Hopefully e4 will ride in on a white horse and save the day, but like all real white horses I wonder what the downside will be (like the poor squire forced to be on "poop" patrol). We shall see... :)
Anyway, was thinking about this today and today's Dilbert made me laugh my butt off... Imagine if it wasn't a web page, but an Eclipse application... and this is how I feel all too often about my OWN stuff. ;)
Yes, it's been a long while (again) since I had an opportunity to write here. But after such a great EclipseCon 2010 experience, I feel it would be a disservice to not talk about it. :)
After joining Red Hat in the middle of 2009, I entered the maelstrom of tooling development in the exciting, chaotic world of Red Hat and JBoss. Leaving Sybase was tough, but it was time to do something different after nearly 13 years at New Era and Sybase. But it was a shock to the system to go from the slow and steady of Sybase to the full speed ahead of Red Hat.
That said, I've had little time to spend on DTP at Eclipse. I feel bad about this. But I'm trying to help as much as I can, just like Brian and Hemant from IBM and Linda from Actuate. None of us can spend as much time as we might like on this great project.
So I went to EclipseCon 2010 with a bit of trepidation. How would DTP be received? We really don't have much to show in our Helios release beyond a few fixes here and there.
We had one talk for DTP this year - DTP in the Real World. I spoke about our improved RCP support in DTP and provided a plea for more community involvement. And Ruth Soliani, from the Eldorado Research Institute in Brazil, who spoke about how they used DTP in their MotoDev Development Studio product (with Motorola) to connect to a SQLite database on an Android device. Pretty darn cool stuff there and they were very kind to say nice things about the DTP team. :)
On the first night of the conference, we had a DTP Birds of a Feather (BoF) that was very encouraging. We met Ray and Chris from Ingres who will be helping us out from that side of the DBMS world where they can. We met Shenxue Zhou from Oracle, who we've been trying to help out as we can as well.
So the show of community support was awesome. At EclipseCon 2009, we had a very low attendance to DTP talks and nobody attended the BoF. This year we had 30-40 people attend the DTP talk and 3 people (beyond the DTP PMC) show up, plus one guy who was hoping DTP meant "Desktop Publishing" (Sorry about that!). We had great conversations with Ruth's team, the guys from Ingres, and Shengxoe from Oracle.
Now I'm actually hopeful DTP will survive. And that's a good thing!
A big thanks go to Oisin Hurley and Don Smith who put on a terrific conference this year. Every talk I went to had a good number of people attending and a few were standing room only (like Mik Kiersten's talk about Mylyn!). Not to mention the awesome keynotes and the giant moon robots that looked like something out of The Matrix. :)
Thanks to everyone who attended and especially the DTP community who's coming back to life!
Wow... It's been a while since I last wrote on this blog. I've been keeping busy at Red Hat since I hopped the fence back in June. :)
Unfortunately, with Sybase's reduction in DTP resources and a few other folks we've lost by attrition, we're suffering from a serious lack of help in the Connectivity and Enablement projects at the moment. Though Linda from Actuate helps out in Connectivity every now and then, it's pretty much just yours truly with occasional help from our friends at Codehoop. And my time these days is pretty minimal for DTP.
Talking with Brian Payton, our fearless leader these days in DTP, it came up that with the small core of folks involved it was like we were in a book "Hitchhiking Through Europe on Pennies a Day" - not getting too far, but when you do get picked up and make some progress on your journey it's often for a brief burst of speed and then you're out of the car on foot again.
So we're looking for a few hitchhikers to help us out.
I come to you, our friends in the DTP community and the broader Eclipse community, and ask for help. We're not asking for full time, devoted folks. We're asking that if you get some time and want to dig into DTP, we have lots of Bugzilla entries that could use some tender loving care.
If everyone who uses DTP would dig into one DTP bug every few months and provide a patch, I'm pretty sure our list of issues would decrease dramatically.
We already have a few mediums out there to communicate... We have the Eclipse DTP mailing lists and newsgroup (check out http://wiki.eclipse.org/DTP_New_Committer_Info to get the list of how to find those resources). And I just created a new IRC chat (#eclipse-dtp) on freenode that I'll be on any time I happen to be logged in. Maybe we can get the conversation going between other DTP community members and bring things back to life a bit!
Personally, I've been involved with DTP since 2006 and have really enjoyed working with everyone I've met. Who knows who you might meet? We can't offer fame or fortune for your contributions, but we can definitely offer our gratitude and most likely the gratitude of a grateful DTP community.
It's been a while since I last posted anything on this blog, but I want to assure you it's not dead. Well, not quite anyway. My new position at Red Hat has been and will continue to be a challenge - a good one! But that means I have less time to spend on DTP topics...
I know I still owe (oh ye few who read these words) the remainder of the YouTube/DTP plug-in I promised way back in March with my EclipseCon 2009 talk. But I hope to get back to that sooner than later.
In the meantime, I wanted to congratulate Brian Payton from IBM for becoming the new DTP lead. He's a great guy who's kept a handle on the SQL Editor for quite a while now and I'm sure he'll do great for the rest of DTP too! I'll continue to help out where I can and be involved, but to a much smaller extent.
As such, if you see him around please welcome Brian P to his new position if you get a chance. I'm sure he'd be happy to hear from our community!
We're in the process of finishing up 1.7.1 for the end of September with the Galileo SR1 release train and will then see what we can do for Helios.
If you, our great community, have some extra cycles to help out, we'd love to have you join the party. Give us a holler on the mailing lists or newsgroups and let us know what you're thinking. The more the merrier!
Thanks a ton for your continued support of DTP and hopefully I'll get back on track with some new posts here before long. :)
Some of you may have already known that I was leaving the leadership of DTP at the end of Galileo. If you didn't already know, Sybase is pulling away from project leadership for now. They have their reasons for doing so, and though valid I am sad to see us retreat from DTP after the last four years.
That said, it's been an honor to help lead the DTP project over the last year and I'm proud to have been involved with all the participants and the community for the last four years. I've learned a ton and met some truly amazing people. And most of all, I've had fun. Those are always my three criteria for success -- the people I work with, what I learn on the job, and whether the job itself has some elements of fun. It's not always fun, but it has to have a bit at least. :)
I'll miss being as involved as I have been, but still hope to retain my committer status as I shift jobs, leave Sybase, and head to Red Hat at the end of the month. After more than 13 years at New Era and Sybase, I'm leaving to pursue a different opportunity. Definitely time for a change and RH made me an offer I couldn't refuse.
So I'll still be around DTP, just not as much as I have been over the last few years. I'm sure that others will pick up the mantle of DTP leadership and continue to shepherd the project forward. We have a great community that continues to grow and use our code in innovative ways, so I'm hopeful about the future of the project. I will still try and continue to post here as time allows, but I can't guarantee anything.
Thank you to all of you who have helped over the years. I'll still be around and hope to keep in touch!
I saw Dave Carver's post about using MarkMail's indices of the Eclipse mailing lists and was inspired to take a look at the DTP mailing list to see if there were any trends. We seem to follow the same trend as WTP...
We seem to peak around the time of each year's release train, which makes sense, and then drop off a bit after that.
This helps to understand a bit of the adoption curve as was noted in the EclipseCon 2009 keynote "The Social Mind: Designing Like Groups Matter" (you can see the abstract here).
They showed a picture of Wikipedia contributions that looks somewhat similar to the graphs for WTP in Dave's post and this one for the DTP list. Initially there's a lot of contributions and conversation and it starts to drop off over time with only a few people doing the majority of the posting. In our case, the top 5 are all either Sybase or IBM folks, but it's heartening to see that at #6, we have Oracle represented and some of our friends at Actuate as well.
What does this tell us? Honestly not much more than we already knew, but it's good to have another metric. Thanks Dave for pointing out that Markmail is there!
If anyone's interested in the DTP-DEV stats, feel free to check them out here as well.
Now that we know generally what we want to do, we'll start by focusing on making the YouTubeAPIs usable in Eclipse and perform a simple test. Easy enough, right?
So the first thing I had to do was grab the YouTube jars from Google. I found those here. I grabbed the latest version of gdata-samples.java. The YouTube/Google APIs also have some dependencies, so I had to go out and grab imap.jar, mailapi.jar, pop3,jar, and smtp.jar. I was able to re-use a plug-in wrapper for javax.activation.jar from Orbit, which I'll talk about in a sec.
With all of the jars downloaded, I just had to create an Eclipse plug-in wrapper so they were available to other plug-ins. To do this is cake... Right-click in the Package Explorer, select New->Project, and in the list of Wizards select "Plug-in from existing JAR archives". Select your external jars (it will copy them into the plug-in wrapper). I named mine "com.google.gdata.youtube" and unchecked the "Unzip the JAR archives into the project" so it kept the jars as jars, not source code. Click Finish and watch the magic happen.
When it's done, I had to do one last thing to add a dependency. The Google APIs still depend on the javax.activation.jar...
Do you remember I mentioned the Orbit project? Well, you can read more about it here, but the idea is that it provides a repository for a number of third-party projects/resources that are shared across Eclipse. These have already gone through the IP process and are approved for our use. (Note however that even if a library is approved by the Foundation for use by all projects, project teams must still fill out a Contribution Questionnaire and notify the Foundation of their intentions to use a library). And there are quite a few of them. If you look at the latest build (from back in August 2008), you'll see 83 different packages available.
In this case, I just want javax.activation, so I locate it in the list, download it, and drop it in my Eclipse environment. Once the workbench picks it up, I can add it as a dependency in the MANIFEST.MF file for my wrapper plug-in.
Cool. So that pretty much wraps up my jar wrapper plug-in. Not too tough there.
So now what? Now that we have this plug-in, we can write a quick little application to do something with it.
I've gone ahead and created a simple class that does a very basic YouTube search...
public static String TR_FEED_URL = "http://gdata.youtube.com/feeds/api/standardfeeds/top_rated";//$NON-NLS-1$
/** * Return a list of video entries back to the calling method */ public static VideoFeed getResults(String author, String title) throws IOException, ServiceException { YouTubeService myService = new YouTubeService( "", //$NON-NLS-1$ ""); //$NON-NLS-1$
String VIDEO_FEED = TR_FEED_URL; YouTubeQuery query = new YouTubeQuery(new URL(VIDEO_FEED));
//set the author if( (author != null) && author.length() > 0) { query.setAuthor(author); } //set the actual query string if((title != null) && title.length() > 0) { query.setFullTextQuery(title); }
//choose most viewed as the ordering query.setOrderBy(YouTubeQuery.OrderBy.VIEW_COUNT);
//get the video feed VideoFeed feed = myService.query(query,VideoFeed.class); return feed; } }
So all that this really does is get a list of the top rated videos currently at YouTube. Pretty straightforward.
You'll notice a couple of things about the code. You have to have a developer key (your own ID as a developer or one for a particular company) and a client ID (seems you can have many of these). This basically lets the Google & YouTube APIs know that you're legitimately asking for data and aren't some rogue hacker trying to cause trouble. You can get these two items here. Once you have them, you can just create new constants for them and just use the constants.
So if you swap your developer key and client ID into the above code, it should do a quick search. But how should we test it?
I like creating new plug-in projects with example menu actions. To do this is pretty easy... Right-click in the Package Explorer, select New->Project, and in the list of Wizards select "Plug-in Project". Name it and set the plug-in ID and other info, and on the "Templates" page in the wizard, select "Plug-in with a popup menu." By default it keys off an IFile, so you can get to it from the Navigator or Project Navigator in the workbench.
It goes off and creates the basic code and you can then use your new utility class pretty easily by changing the run() method in the action class to look something like this:
public void run(IAction action) { try { VideoFeed feed = UTubeUtils.getResults(null, null); if (feed != null) { if (feed.getEntries() != null && feed.getEntries().size() > 0) { System.out.println("Found some videos..."); Iterator<VideoEntry> iter = feed.getEntries().listIterator(); while (iter.hasNext()) { VideoEntry entry = iter.next(); System.out.println("Video Entry: " + entry.getTitle().getPlainText()); } } // clean up feed = null; } } catch (ServiceException se) { se.printStackTrace(); } catch (IOException ie) { ie.printStackTrace(); } }
When you run the workbench and right-click on your action in the Navigator, you should see something like this in your development workbench console view...
Success! We have a plug-in wrapper for our YouTube jars and their dependencies. And we've verified that we can use those APIs in an Eclipse environment.
Next we have to figure out how to hook up YouTube to DTP and show a video in the workbench. And after that we can fine tune our look and feel to make it easier for our users.
Maybe this was a bit longer to write up than I'd thought originally, but this part of the process only took me about half a day when I was creating this code the first time.
Questions? Comments? Drop me a note here and I'll be happy to get back to you.
Next time I'll write about hooking up YouTube and DTP and how I used the built-in Eclipse web browser UI component to show videos.
On the DTP newsgroup we had a question about using DTP APIs to create a new transient connection profile and then use that to execute some DDL...
It's pretty easy actually... The trick for the transient profile is knowing all the bits and pieces you have to have ahead of time, like the:
provider ID, which is the connection profile type ID
vendor and version, which relate to the vendor/version of the database you're connecting to
and then the driver path. Note that you can also use a pre-defined driver and get the DriverInstance from the DriverManager, then retrieve various properties like the vendor, version, class name, and driver path from there
So one of my presentations at EclipseCon 2009 was "DTPtv and Other Wacky Ideas."
Was this truly a wacky idea? Probably. Who would have thought to merge Eclipse, YouTube, and DTP in one go?
My goal was two-fold... First, I wanted to show that DTP can be used for something more than just databases. Far too often we're pidgeonholed as a provider of database tools. And though we do that, we do much more as well. Second, I wanted to do something out of the usual box, and YouTube is pretty dang far out of the box...
Create a YouTube Search connection profile in DTP so you could create and manage multiple searches in a variety of ways.
Create a viewer that would allow a user to take advantage of YouTube searches on the fly and see the results within the Eclipse IDE or in an RCP application.
Now why would you want to do this you might ask? Good question.
Let's say you write Eclipse RCP applications for a company with a healthy education department. They want to help out beginning users by recording tutorials and putting them up on YouTube. Not only will it help your users, but it works as a bit of helpful marketing for your sales staff. And now that they're doing this, they want a way to be able to take advantage of these YouTube videos right inside the application.
Maybe this isn't so far fetched after all?
In the next series of blog posts, I'll focus on the three steps I took to get this all working. I demoed working code at the conference and will clean it up a little, zip it up, and have it available on a file sharing site soon. I hope to also contribute it back to the Examples project at Eclipse, as it crosses project boundaries.
As always, please feel free to ask questions or make comments as I go through the process. Many of you will find this old hat, but I'm hoping someone can take advantage of the information. :)
I'm still in the process of getting my act back together after EclipseCon 2009 last week in Santa Clara, California. Was a great conference as per usual, and a bit of an eye-opener for me at least as far as the excitement (or lack thereof) for DTP in the conference community.
First, let me say that I am very excited about Amazon's announcement about the AWS Toolkit for Eclipse. Eclipse in the Cloud is a very cool concept and one that I think will prove to be fertile ground for all sorts of interesting applications. The exciting part for me was hearing that the AWS Toolkit team is still looking at using DTP to help them integrate with their SimpleDB database in the Cloud in a future release of the toolkit.
Anything we at DTP can do to help with that effort would be very educational and cool for us. And as always, we'll help wherever we can. :)
Second... There were a TON of great talks at EclipseCon this year. Though E4 seemed to get most of the buzz, I think that runtime talks were running a close second. After attending a number of talks in all parts of the spectrum (business, coding, new tools, and so on), I came away with a ton of cool ideas I'd love to explore if time allowed. Things from exposing DTP as OSGi services, to using the Data Binding APIs, to using Zest to possibly help to visualize a database schema and other things. I have a loooong list of things to explore.
And third, I was bummed about the lack of interest in our DTP talks this year. We had a few people show up at the DTP tutorial on Monday, and I had a few people at my DTPtv talk, but we ended up with an empty room for our set of short talks at the end of Thursday.
Now, I know that DTP is really more of a "plumbing" project and I get that plumbing isn't sexy. But when people put time and effort into creating presentations (and in one case fly from Germany to present), it's disappointing that nobody wanted to listen.
Yes, there were probably extenuating circumstances. I know that many people left the conference early to catch flights and there were other talks that were probably much more exciting (I missed John & Max's talk in the same slot and would have liked to attended). But still...
Even with that bummer deal, I still think it was an excellent conference. Scott Rosenbaum and the program committee (of which I was a very very minor part) did a great job recruiting amazing keynotes and cool folks to come talk about their technologies. And as I said, I came away brimming with ideas for DTP.
So maybe next year will be a better year for DTP... Who knows?
I'll be writing up one or two more posts about my EclipseCon experience this year, including a post about my DTPtv talk, which (though it went short), I had a great time doing.
Thanks to everybody involved in the conference this year. Let's do it again next year!
Yes, it's almost that time again... EclipseCon 2009 starts with a bang on Monday. Can you believe it? It's already here!!
I head out to the (hopefully sunny) state of California on Sunday morning early for a boatload of meetings that afternoon and then DTP has a tutorial bright and early Monday morning at 8am.
But I thought I'd fill everyone in on what's cool in the world of DTP at EclipseCon this year...
We have our tutorial obviously -- "Using and Extending Eclipse Data Tools (DTP)" on Monday morning at 8am. If you're planning on attending, please check out the list of pre-requisites. We'll start with the DTP tooling, talk about DTP APIs, and then go a bit into how to extend the ODA and SQL editor for your own particular uses. Linda Chan (Actuate), Brian Payton (IBM), and myself will be presenting.
So it's not forgotten, we also have a Birds of a Feather session on Monday night. If you want to come and chat, ask questions, and see what's going on in the world of DTP please drop by!
And if you're going to attend the Eclipse Community Spotlight panel at the end of the conference, you'll get to see a bunch of us talking about what's going on in the world of Eclipse.
So be sure to check us out while you're at EclipseCon! I hope to see you there!
A couple of weeks ago, Wayne Beaton was kind enough to put up with me for a podcast in his series about EclipseCon 2009. What did we talk about? The Data Tools Platform of course!
We chatted about some of the talks we have for DTP at EclipseCon this year. And we of course hope to see you DTP community members at each of them... ok, maybe just a few (there are so many great presentations, you almost wish you could clone yourself!). But definitely stop by!
Though I still think I sound like Kermit the Frog, the podcast is up there for all to hear at Eclipse Live. Check it out and let me know what you think!
I'm always amazed by the depth and breadth of talks at EclipseCon and this year is no different. In the Data Tooling category, we have a diverse set of talks (you can see the list here) on everything from some new tooling we've been working on, updates to the Graphical SQL Query Builder, how Ingres is rolling DTP components in new and unique ways, to using YouTube in DTP and how a commercial vendor (IBM) is using and extending DTP APIs for their PureQuery product.
I have to admit I'm sort of partial to the YouTube presentation I'm doing :), but I'm very curious to hear Ingres and IBM talk about their tooling and products and how DTP is playing a role in those.
For those of you just getting started with DTP, we have a tutorial scheduled for the Monday of the conference that's going to walk through a ton of topics from adding a new JDBC driver to the mix, to supporting a new database, and customizing SQL syntax and so on...
DTP is much more than just a great set of tools for data access... It's a great community. And EclipseCon is when that community comes together.
Yes, the holidays are almost upon us... But even better than that, EclipseCon 2009 is just around the corner! (Ok, maybe not RIGHT around the corner, but three months will zip by in no time.)
This year in the Data Tools track we have a tutorial coming up and bunch of cool talks from a number of different directions.
Though I'm helping with the tutorial this year and moderating a block of short talks, I also am talking about how to use DTP to connect to something other than a database. After all, not all data is in databases!
My long talk this year will show how DTP and the Data Source Explorer can be used for searching and viewing YouTube videos in Eclipse. How do these two worlds meet? Come to my talk and find out!
Besides that, I get to moderate a set of three cool short talks. These bright folks will talk about how DTP is being used in RCP as a database developer's type of tool, what's going on with the SQL Query Builder in Galileo, and how DTP is being used in cool ways by a commercial application.
So be sure to check out some of our talks this year! In another post, I'll talk some about what to expect from our tutorial and some of the other cool talks going on at EC2009 that I'm excited about!
Register today and don't forget to reserve a room at the hotel (it fills up fast!)!
I recently spent about a day and a half chasing my tail trying to track down some bizarre out of memory errors I was running into with Ganymede SR1 when debugging some DTP stuff and thought I'd pass along what I learned. I was continually running out of heap space while debugging, which was very troubling.
At first, I thought I had somehow corrupted my workspace. So I created a new workspace and tried it again (several times actually) and ended up with the same problem.
Next, I thought I'd try the Galileo Platform Galileo M3 build (along with the associated GEF, EMF, and DTP builds) and see if I got the error. At first I didn't, and I thought 3.5 might have fixed the problem... [sigh] No luck.
So then I started poking around on Google, trying to figure out how to bump up my heap space.
I kept running across this suggestion (which after thinking about it was kind a "well duh" kind of thing):
"Add -Xms256M -Xmx512M to the VM arguments for the runtime configuration or on the main Eclipse command line when you start it up..."
Lo and behold it works now in Galileo and Ganymede. Life is good.
But it was a frustrating end to the week, only to discover that I was just oblivious to the simple solution. :(
Hope this saves someone else from the pain and suffering!
We would love to know how you are using DTP -- either as an end user, an adopter, or an extender. Tell your story via the DTP mailing list or newsgroup!
We seem to peak around the time of each year's release train, which makes sense, and then drop off a bit after that. 
When you run the workbench and right-click on your action in the Navigator, you should see something like this in your development workbench console view...![Reblog this post [with Zemanta]](https://lh3.googleusercontent.com/blogger_img_proxy/AEn0k_tNKdxgFiTGzB9l4BCgUAQa7Or5bycS2ocnCvXUMfiPeAc1xsQ-d4dEw6XX1zNc2-_dr0FFaIgJu9cuqrh0y_nPVx8yQx7LQ5y6DbsnBjeGaBUzSQ0yOGGzTCb72yZrPkMErKCpRXO1OoiHSWJ0aUyM=s0-d)
