-----------------------------------------
For the MyFaces Core 2.0 MANIFEST bug, please file an issue against MyFaces
Core! Thanks!
> Make Trinidad OSGi ready
> ------------------------

> Key: TRINIDAD-1901
> URL: https://issues.apache.org/jira/browse/TRINIDAD-1901
> Project: MyFaces Trinidad
> Issue Type: Improvement
> Affects Versions: 2.0.0.3-core
> Reporter: Frank Mittag
> Priority: Minor

> Hi,
> it would be great to create an OSGi ready version of Trinidad (and MyFaces).
> I'm using Trinidad together with MyFaces in the Eclipse Virgo runtime (former
> Spring DM Server), but the problems are valid for every OSGi environment.
> In the first place the API and the IMPL jars need an updated/improved
> OSGi-ready MANIFEST file exposing the typical OSGi metadata. The content
> could be created with tools like BND from Peter Kriens which could run as
> part of the build process (see other projects like Apache Felix, etc.)
> But normally this is not enough the make a library OSGi-ready. The nature of
> OSGi allows to run several TRINIDAD's in parallel in the same runtime even
> in different versions.
> This leads often to conflicts with singleton objects or class loading issues.
> There are different usage scenarios where Trinidad should fit:
> 1. Scenario: Usage of TRINIDAD in two different web apps inside an OSGi
> runtime.
> So you have ideally
> 1 API bundle
> 1. WAR with the IMPL jar in the lib folder
> 2. WAR with the IMPL jar in the lib folder
> or
> 1. WAR with the API jar and the IMPL jar in the lib folder
> 2. WAR with the API jar and the IMPL jar in the lib folder
> 2.Scenario: Usage of TRINIDAD in different web apps in two different versions
> inside an OSGi runtime.
> So you have ideally
> 1 API bundle 1.2.14
> 1 API bundle 2.0.0.3
> 1. WAR with the IMPL 1.2.14 jar in the lib folder
> 2. WAR with the IMPL 2.0.0.3 jar in the lib folder
> 3. WAR with the IMPL 2.0.0.3 jar in the lib folder
> or
> 1. WAR with the API jar and IMPL 1.2.14 jar in the lib folder
> 2. WAR with the API jar and IMPL 2.0.0.3 jar in the lib folder
> 3. WAR with the API jar and IMPL 2.0.0.3 jar in the lib folder
> Even more better would be to have just one API and IMPL bundle in the whole
> runtime and just reference the bundles from the web app, but I guess this
> would probably require some refactoring of TRINIDAD.
> The pattern also applies to the MYFACES libs.
> Regards,
> Frank
