OSGi BundleFest 2008
This year we had our first BundleFest. With all the specification work going on for Enterprise, Residential, and Mobile (which is pushing a lot on the Core Platform) we felt that we needed some time to work closely together on the RIs and the Compliance Tests. The location was decided to be Montpellier, France, at least we would have a chance on some sunshine. Well, we actually had 5 sunny days; unfortunately, we were so caught up in work that we went in with dusk and came out with dark. Then again, we could work with the windows wide open.
A lot was accomplished. A major task was RFC 119 and getting the test cases and reference implementations up and running. TIBCO, Siemens, and IONA worked intensely to get it all working. During the evaluation they made it clear that they would never have been able to get it all working so quickly if we had tried to do this via e-mail.
ProSyst had two projects to work on: Transactions (RFC 98) and improvements on the test cases for the Mobile specification. The transaction work is mostly done because it could use the transaction code in Geronimo.
Some heroic work was done on the Mobile testcases. We have moved the OSGi build to "bnd" and this means quite a lot of work per test case because the OSGi test cases are non-trivial. They cause us to have over 900 bundles in the build. Obviously, some of these test case are quite complex.
SpringSource was one of the first companies to register for the BundleFest and they sent two people. Though their intent was to do some real coding, it turned out that they did not reach that goal until the last day. However, the specification improved significantly with the help of the folks from IBM working on the Compliance Tests that were on a continuous real time chat.
NTT worked on writing test cases for changes in the framework regarding permissions. This was not an easy task because the test framework in the OSGi build is Equinox and it does not have the necessary changes yet. Though the new build makes it very easy to switch frameworks, it does require that the framework implements the new RFC 132 for framework launching.
On Friday we evaluated the week and the judgment was overwhelmingly positive. Not only did we all have a very good time, we also got a lot of work done. As Tim Diekmann said: "Without the BundleFest, it would have cost us weeks to get this far." And I tend to agree. It is therefore likely that we will repeat this type of event in the future.

Kind regards,
Peter Kriens

Expert Group Updates and Latest Happenings
REG
The Residential Expert Group (REG) had a meeting September 18 and 19 in New Jersey, together with representatives of the Mobile Expert Group (MEG) on the first day and a joined meeting with the Core Platform Expert Group (CPEG) on the second day. Besides the progressing work on the RFP’s and RFC’s, common interest for future work items has been discussed in a meeting with MEG representatives. The fixed and mobile telecommunications markets are merging in many regards, so both groups identified a couple of work items that would enhance the ease of use and overarching integration of services.
Work on the RFP’s and RFC’s is also continuing. Good progress has been made in defining the residential management tree (RFC 140). In addition RFP 110 – “Security Improvement for Configuration Admin Service” and RFP 113 – “Requirements for an IGD Service” have been approved by the Requirements Committee.
Another important item is the work on a White Paper that presents and explains a remote management reference architecture supporting both single and multiple service providers.

EEG
The Enterprise Expert Group (EEG) has been working to complete the designs for Distributed OSGi (RFC 119) and the OSGi Blueprint Service (RCF 124 - derived from Spring), including a lot of email discussion, a face to face meeting September 18-19 in New Jersey, and good participation at the OSGi Bundlefest the week of October 13 in Montpellier, France. A lot of coding was done at the Bundlefest on the RI and Compliance Test components for RFC 119 and on the RI for RFC 124 as well. So these significant parts of the upcoming release are nearing completion after nearly two years of work.
Now the EEG is turning its attention to the very important work of figuring out the best way to approach integrating major parts of Java EE into an OSGi environment, including JDBC & JPA for persistence, JNDI for directory services, enhanced Web application support, and JTA for transactions, to name a few. After a lengthy discussion and several revisions, RFP 98 "OSGi Platform and Java EE integration" was recently approved, which provides the umbrella under which the Java EE mapping work can progress to the design phase. Members of the EEG are now drafting and refining several RFCs related to Java EE components and how they fit within the OSGi Framework.
The goal of completing the next release in time for the next major release of Eclipse remains intact, although time is getting short, the group is focused well on its current activities. While the work on the Distributed OSGi and the Blueprint Service designs starts to ramp down and turn to work on the formal specification, the RI, and the Compliance Tests, work on the Java EE mapping is ramping up. Altogether it remains an ambitious effort, but with a lot of potential advantages for the OSGi community as it moves into the enterprise space.
