Subject Re: OpenEJB in an OSGi container
Date Thu, 09 Oct 2008 19:47:01 GMT
It's been a long time since I work on that and I still have not found
the time to continue this integration work.
Anyway, the code I used is available at:
  http://svn.apache.org/repos/asf/servicemix/smx4/features/branches/ejb3
It uses a spring-powered bundle to set up OpenEJB:
  http://svn.apache.org/repos/asf/servicemix/smx4/features/branches/ejb3/deployer/src/main/resources/META-INF/spring/openejb-spring.xml
and the related java classes are available at:
  http://svn.apache.org/repos/asf/servicemix/smx4/features/branches/ejb3/deployer/src/main/java/org/apache/servicemix/ejb3/deployer/

Unfortunately, this may be a bit outdated :-(

Anyway, the idea was to be able to listen to newly installed bundles
and discover EJB inside those so that they are automatically
configured as plain EJB or web services.
Though, this was in the context of ServiceMix, where the EJBs were to
be exposed on the JBI bus and eventually through HTTP/SOAP too.
