We will release the core specifications first (framework, some services). This will be followed with additional specification for mobile devices and vehicles (and possibly others in the future). These are all built upon the core specifications. JSR 232 is the consuming the mobile spec and portions of the core spec to define a next generation mobile java platform. > > >and what's the relationship among Oscar , OSGi R4, JSR 277 and JSR 232 ？ > > > > The only thing that ties all of these four items together is my involvement.

Oscar is a OSS implementation of the OSGi framework (and perhaps several other areas of the OSGi spec). OSGi R4 is a specification. There are both commercial products which implement OSGi and there are also OSS projects such as Oscar and Eclipse which implement it. JSR 232 I explained above. JSR 277 is a new JSR which plans to look at the issue of modularity in the JRE. OSGi R4 is already well advanced in the area of modularity and we hope to work with 277 to maximize reuse of the OSGi work to avoid fragmentation in this area. Again, 277 is very new, so nothing concrete has been decided there yet. > > -> richard > > > BJ Hargrave Senior Software Engineer, IBM OSGi Fellow and CTO of the OSGi Alliance [EMAIL PROTECTED] Office: +1 407 849 9117 Mobile: +1 386 848 3788
