AJDT for Helios now available
Just a quick note to let you know that AJDT targeting Helios (Eclipse 3.6) is now available from the following update site: http://download.eclipse.org/tools/ajdt/36/dev/updateAspectJ-aware PDE export facilities are currently broken. I am not planning on fixing it. Instead, I have been working with the PDE team on an alternative solution. See Ability to override javac task during pde builds (Bugzilla). I'll write more about this later, but the solution is much more elegant than what is currently available in AJDT for 3.5 and earlier.Also, as a bonus, this version includes intertype declaration (ITD) -aware Java search. Finally, ITDs are completely first-class citizens in the workspace. I'll write more about this later, too.
JWT moved to Eclipse SOA
The Eclipse SOA top-level project has a new member: the Java Workflow Tooling (JWT) project finished the Move Review successfully. JWT aims to build design time, development time and runtime workflow tools and to foster an ecosystem of interoperable Business Process Management (BPM) platforms.Therefore, it supports the enrichment of business process models (e.g. initially modeled in BPMN) with runtime data or services, allows the user to generate code (e.g. in XPDL or to BPEL) and provides an extensible mechanism to customize the models via aspects.Thereby, JWT has already been part of Eclipse Galileo. With this move, the project has once more proven to be mature. JWT will graduate from incubation probably together with or shortly after the Helios release in June 2010.Congratulations to the team and the new project leads of JWT!Together with the move review, I took a step back and will only be a committer of the JWT project anymore, but no longer project co-lead. Reason for this is that I finished my Ph.D. successfully and work as a technical consultant now (my employer is Senacor Technologies) which leaves me with less time for JWT. In my opinion being a project lead requires a lot more time than only one hour every two weeks or so. As Chris Saad already supported me in the last few years, it was only natural that he stepped forward to fill this place.I would like to say thanks for your support, Chris, as well as to my project co-lead colleague and friend, Marc Dutoo (OpenWide SA). We had been a great team and complemented each other perfectly. Now as a committer, I hope to find more time to code again while being less focused on the roadmap, release train, etc. as I know that those will be in good hands at Chris and Marc.One of the good things of my new job is my current location: I'm working at a project for the Deutsche Post at the moment and am therefore only meters away from Sopera who are deeply involved in the Eclipse SOA project. I already met some of the guys during lunch and hope that we can use the close distance to bring the Eclipse SOA projects closer together, too.To learn more about JWT and the whole SOA top-level project, come to EclipseCon and follow the talk about Eclipse SOA TLP: Lock, Stock and Barrel. If you have questions about JWT, feel free to ask the two project co-leads who will both be available at the talk.
Listen up Europeans!
Yes, we'll do it again. For all of you who are not getting out of Eclipse Con and Santa Clara on Thursday: Come by and have a drink with us European Eclipse enthusiasts. As every year, we will gather at David's Restaurant @ Santa Clara Golf and Tennis Club, about 0.2 miles from the convention center. And as every year, we will start our little event around 7pm Pacific time.
Thanks to the German OSGi User Group we have been able to raise our liquids budget by 300 Euro. If you are from Europe and your company wants to become a sponsor too, please let me know! We'll happily add your money to pay the tap.
PS: If you don't have a European passport, we'll let you in too :-) Promise! You might not qualify for a large beer though.

Equinox OSGi Book Finally Here
When I came home last night, I was delighted to find a package (because I’m a fan of gifts).

In my biased opinion, this is best OSGi book on the market. I’ve had the honor to see the book evolve while it [...]
Eclipse Amalgamation 2.0
I'm waiting for a nightly M6 Modeling package to get downloaded on my laptop. As I've got a few hours to wait getting it I'll use this chance to give news about the Amalgamation project.It's a well known fact that the Eclipse Modeling Project is myriad of small focused projects, Kenn is working on sanity checks for each of those project, more than 50 ! The benefits of this organization is that you can choose which bits you want to use depending on your use case but this flexibility come to a cost: making sure there is no overlap between proposals is often tricky and making sure those projects taken as a whole are providing a consistent platform is even more challenging.A few years ago the Eclipse Modeling Amalgamation project was created and started by providing Eclipse distros tailored for specific needs and an "All Eclipse Modeling in One Package" distro through EPP. At some point the project staled and during last October a new team gathered and I've been designated project lead.Most users and adopters are consuming the Eclipse Modeling Project through the EPP package, one don't have to figure out how to browse and install the projects you need. But this package was including all of modeling, as such it was huge, cluttered, un-tested, and nobody could really use it.Downloads of the package felt down and the Eclipse Modeling project has a whole probably suffered from that.My first objective for the Amalgam project was to update the package to get a sane one : changing our big messy package to an Eclipse Modeling SDK composed of the core runtime components and framework : EMF core and its low UI profile companions : XSD, Transaction, Validation, Mint and compare Graphical support with GEF and GMF runtime OCL and UML2 : you can't really live without those standards. CDO : it brings EMF - as a framework - to another level with collaborative editing and remote model repository.This set of features + Eclipse SDK and Mylyn is composing our new platform, and we went from almost 400 to 250Mb. It's still big but hey, it's an SDK !Still, many more great and useful components are built within the Eclipse Modeling Project and getting those to install was painfull. Mylyn was already providing a solution to that : a discovery UI :In the meantime during the year this discovery support has been moving from Mylyn to P2.As a user, having this UI makes my life easier, I can install components without even thinking about where I'll find the pieces and P2 is taking care of the requirements and consistency of my Eclipse installation, I'm looking forward to hear from your feedback about it when the M6 Package will be out.This modeling platform is a basis we'll test and polish to get a streamlined user experience and we'll have to organize ourselves to make sure to release a tested, used, and clean platform. The Eclipse Modeling Panel will be a perfect time to give your opinion and feedback, do not miss it, it's on Monday !

Confessions for the EclipseCon Speaker
I recently read a very funny and informative book about the pitfalls to avoid while speaking in public. Confessions of a Public Speaker by Scott Berkun. If you need a great book to read on the plane to EclipseCon, I highly recommend it.Some of the most important points in the bookPractice, practice practice your talk. This allows you to optimize the organization of your talk and smooth out your delivery. If you are speaking to a small number of people in a large room, try to convince them to move to the front of the room. People who are sitting together will change the dynamic of the talk. Speaking to a group of people who are scattered around a large room is not optimal.Go over the agenda in your introduction. For instance, say "I'm going to talk about five points at three minutes a pop. The final five minutes will be for you to ask questions". This will give people an idea of what to expect.Interact with your audience. Ask trivia questions, for a show of hands or ask the audience to solve a problem.I notice that a lot of people are working during talks instead of listening to the talk. My employer paid money to send me to a conference and I'm investing my time. So I make a point listen instead of doing my regular job even though it will be painful to catch up with work later on. In the book, he suggests asking people to close their laptops and if they are bored after five minutes, go back to surfing the web. Again, the audience it gets the audience engaged in your talk and your show that your care about your audience. Of course, if they are blogging or tweeting about how interesting your talk is, they can keep the laptop open :-)The final chapter of the book describes some of the worst things that have happened while people giving a presentation. There's fire, water, and SWAT teams. Hilarious. I don't give that many presentations in my day to day job of building bundles, so I found this book was a great resource . With that note, I must get back to writing slides, practicing my talks, and fixing bugs.
EclipseCon Sessions
EclipseCon starts in next week and there are plenty of sessions relevant to Virgo.I'm doing the main Virgo talk and there's a Virgo launch BoF session (and a proposed BoF on Virgo tooling). I'm on panels on Gemini and the future of application servers and co-leading a BoF on application models for OSGi. I'm also giving a brief update on Virgo at the Eclipse Membership Meeting.Then there's the main Gemini talk, an EclipseRT BoF, and other sessions on OSGi, Apache Aries, Maven and OSGi, and JPA and OSGi.

OSGi, and How It Got That Way

OSGi/EclipseRT in Amazon Cloud
I've created a public Amazon Image (AMI) from a recent build (3.6 stream) of the EclipseRT. The parts of EclipseRT included in this image were Jetty, Equinox, p2 provisioning, and a very simple Hello World servlet application (with source).Here is documentation about how to get the image, start an EC2 instance, and run your own server. Here is an instance of this Hello World servlet application running on my instance.
PsychoPath XPath 2.0 version 1.1 Milestone 6

The next Milestone will focus purely on bug fixes and documentation updates. Also, as of Milestone 5 of Web Tools Platform 3.2, PsychoPath is the XPath 2.0 engine for the XPath View. If setting your XPath preferences in the view to XPath 2.0, the PsychoPath processor will be used.As always, the user manual is available on the wiki, and we encourage adopters and the community to contribute to it's up keep. We plan to freeze the documentation near the end of Milestone 7 and incorporate it into the release candidate builds.
Immigration Documents
I was recently reminded of the disconnect between organizational image and organizational reality. In software development organizations one often sees a professed focus on productivity and quality. Sometimes this is bolstered by the sincere adoption of some kind of “development philosophy” that has some spiffy name like “agile,” “srum,” “pair,” or “test driven.” [...]

Running a SQL Script on startup in EclipseLink
Sometimes, when working with DDL generation it's useful to run a script to clean up the database first. In Hibernate if you put a file called "import.sql" on your classpath its contents will be sent to the database. Personally I'm not a fan of magic filenames but this can be a useful feature.There's no built in support for this in EclipseLink but it's easy to do thank's to EclipseLink's high extensibility. Here's a quick solution I came up with: I simply register an event listener for the session postLogin event and in the handler I read a file and send each SQL statement to the database--nice and clean. I went a little further and supported setting the name of the file as a persistence unit property. You can specify this all in code or in the persistence.xml. The ImportSQL class is configured as a SessionCustomizer through a persistence unit property which, on the postLogin event, reads the file identified by the "import.sql.file" property. This property is also specified as a persistence unit property which is passed to createEntityManagerFactory. This example also shows how you can define and use your own persistence unit properties.import org.eclipse.persistence.config.SessionCustomizer;import org.eclipse.persistence.sessions.Session;import org.eclipse.persistence.sessions.SessionEvent;import org.eclipse.persistence.sessions.SessionEventAdapter;import org.eclipse.persistence.sessions.UnitOfWork;public class ImportSQL implements SessionCustomizer { private void importSql(UnitOfWork unitOfWork, String fileName) { // Open file // Execute each line, e.g., // unitOfWork.executeNonSelectingSQL("select 1 from dual"); } @Override public void customize(Session session) throws Exception { session.getEventManager().addListener(new SessionEventAdapter() { @Override public void postLogin(SessionEvent event) { String fileName = (String) event.getSession().getProperty("import.sql.file"); UnitOfWork unitOfWork = event.getSession().acquireUnitOfWork(); importSql(unitOfWork, fileName); unitOfWork.commit() } }); } public static void main(String[] args) { Map properties = new HashMap(); // Enable DDL Generation properties.put(PersistenceUnitProperties.DDL_GENERATION, PersistenceUnitProperties.DROP_AND_CREATE); properties.put(PersistenceUnitProperties.DDL_GENERATION_MODE, PersistenceUnitProperties.DDL_DATABASE_GENERATION); // Configure Session Customizer which will pipe sql file to db before DDL Generation runs properties.put(PersistenceUnitProperties.SESSION_CUSTOMIZER, "model.ImportSQL"); properties.put("import.sql.file","/tmp/someddl.sql"); EntityManagerFactory emf = Persistence .createEntityManagerFactory("employee", properties);
Congratulations to Ed, Chris, and Boris
Congratulations to the new committer board reps: Ed, Chris, and Boris.All three are immensely talented individually and will be even better as a team: Ed with his skills in coordinating multiple related projects; Chris with his experience attracting new technologies and mentoring non-corporate projects; and Boris with his extensive knowledge of what is needed to support the core committers. I know they will represent the needs of the most important part of the Eclipse community -- the engine of production and innovation -- the committers and contributors (especially the core committers). It will be hard work, but these three have stepped up to the challenge and I look forward to their accomplishments.Congratulations!
IFile.getContentDescription() returns null on files from the workbench. Advice?
When Bioclipse reads filed its workspace, it used IFile.getContentDescription() in version 2.0 and 2.2. However, I now note that unit tests that use this method fail where they used to work in earlier versions. Instead of returning something, I get a null. An example unit test looks like: propane = cdk.loadMolecule(path); Assert.assertNotNull(propane.getResource()); Assert.assertTrue(propane.getResource() instanceof IFile); IFile resource = (IFile)propane.getResource(); Assert.assertNotNull(resource.getContentDescription()); IContentType type = resource.getContentDescription().getContentType(); Assert.assertNotNull(type); IChemFormat format = cdk.determineFormat(type); Assert.assertNotNull(format); Assert.assertEquals(MDLV2000Format.getInstance(), format);This test uses the getContentDescription() to get a content description and converts it to a CDK library specific format type.The JavaDoc lists this methods as more efficient alternative:Calling this method produces a similar effect as calling getDescriptionFor(getContents(), getName(), IContentDescription.ALL) on IContentTypeManager, but provides better opportunities for improved performance.As it used to work, I am considering the option it is a bug. But at the same time, maybe best practices have change? Should I keep using this method, explore the cause, perhaps file a bug report, or start using getDescriptionFor(getContents(), getName(), IContentDescription.ALL)?
