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
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 parallele, 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)
