Hello,
I've kind of problem with EJB3 injection using stripes. I'm new to this
framework, and I have to mention that I'm neither familiar with Struts
use. My JEE web experience comes from Seam use only. So it's strongly
possible I'm missing something in this stripes use case.
Environment description:
- JDK 1.6
- JBoss 5.0.1 GA (for JVM 1.6)
Project structure:
--> EAR
--> WAR : contains stripes ActionBeans, jsp, etc
--> EJB-JAR : contains EJB 3.0 both entity & business Beans
Problem:
I want to access a Stateless Bean from a Stripes ActionBean. I followed
the documentation to use EJB3 Interceptor, but no EJB instance is
injected into my ActionBean EJB field (field remains null). It seems to
have no JNDI resolution problem (verified with the JMX-console in
JBoss).
So here is my code, if someone can help...
Thanks,
Regards,
PC
