----------------------------------------------

Frank,

for myfaces - there was some work (in order to run w/ geronimo) done, I think...
(talking about MyFaces2)

regarding trinidad I see no reason why to do it for older stuff. If we do, than 2.x IMO

> 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
