Florent Guillaume resolved NXP-6677.
------------------------------------
Resolution: Fixed
> Remove EJB facade from default distributions
> --------------------------------------------
>
> Key: NXP-6677
> URL: https://jira.nuxeo.com/browse/NXP-6677
> Project: Nuxeo Enterprise Platform
> Issue Type: User story
> Components: Infrastructure
> Reporter: Thierry Delprat
> Assignee: Florent Guillaume
> Fix For: 5.4.3
>
>
> Since we upgraded to JBoss 5, ejb3 support has become a real pain:
> - deployment is very slow and eats a lot of memory
> - a lot of bugs that we had to walkaround
> - application is about twice slower under load when using EJB3
> In parallel, we don't really need EJB3 support anymore:
> - remoting is done via content-automation
> - in specific cases VCS Client/Server mode could be used
> - new shell relies on automation
> - transaction demarcation is completly managed by Nuxeo
> This means we can get ridd of the EJB3 facades:
> - remove bundles from default distributions
> - double performances under JBoss 5
> If needed, we could maintains a compat assembly containing the facacdes?
> Associated work includes:
> - remove the facades
> - be sure to correctly integrate the JCA pooling without using
> DocumentManagerBean
> - check behavior for Rollback in case of runtime errors
> - check JPA integraton (i.e. try to get the JPA context from the container
> now that we can not inject it via EJBContext)
