Access EJB using dependency injection from managed bean
Posted: Oct 17, 2006 4:12 AM

Hello,

I've built a JSF application. I want to access a session bean using EJB3 dependency injection but I keep having HTTP 500 error.
When I try to access the same session bean from a servlet, there is no problem.
When I access my session from my managed bean using standard context lookup I have no problem either.

Would it be that the @EJB annotation is only valid for servlets and not for other type of component (like a JSF managed bean) ?

Thanks for hint.

Olivier

Additional information: I did redeploy my application under glassfish it seems to work fine, ie. the EJB gets injected in the managed bean using @EJB annotation.

I would be grateful if someone could hint me about why it does not seem to work in oc4j 10.1.3.1.0 ?

Thanks

Olivier

DI is not supported for any kind of application class in a J2EE 5 application.
http://forums.oracle.com/forums/thread.jspa?threadID=447310

If you have a look at the J2EE 5 spec, the classes where DI is supported are listed on page 64.

Component classes supporting injection
Servlet: servlets, servlet filters, event listeners
JSP: tag handlers, tag library event listeners
JSF: scoped managed beans
JAX-WS: service endpoints, handlers
EJB: beans, interceptors
Java EE platform: main class (static), login callback handler

So if you want to use DI from a JSF scope managed bean, it must be supported.
