[jboss-jira] [JBoss JIRA] Commented: (JBAS-7980) Dependency Injection inconsistent with EJB3.1/JAX-RS

Dependency Injection inconsistent with EJB3.1/JAX-RS ---------------------------------------------------- Key: JBAS-7980 URL: https://jira.jboss.org/browse/JBAS-7980 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: EJB3 Affects Versions: 6.0.0.M2, 6.0.0.M3 Environment: Redhat Linux 4.1.2-41 Reporter: Jon Kennedy Assignee: Carlo de Wolf I'm making use of the recent EJB3.1 support in JBoss6M2 to deploy a stateless session bean within a war. This bean also implements a JAX-RS annotated interface and is called as a web service. The session bean uses dependency injection to get a JPA EntityManager and the EJB SessionContext: @Resource private SessionContext context; @PersistenceContext(unitName="drs2_services") private EntityManager em; The problem is that calling my service sometimes fails with a NullPointerException where I make use of the EntityManager or the SessionContext. This behavior is inconsistent and sometimes works. To add more detail: If I call the service and I get a NullPointerException on the EntityManager, I can work around the issue by restarting the service until the call succeeds. After it succeeds once, I won't see the NullPointerException again (until, perhaps, I restart the JBoss again). The SessionContext issue is a little trickier. I am able to call my webservice from the browser successfully, but when using Java's HttpUrlConnection class, I consistently get a NullPointerException on the SessionContext. I followed the RestEasy 1.2 guide for configuring and annotating my project, specifically chapter 38 "EJB Integration." I didn't bundle the ReastEasy jars in my war since they are bundled with JBoss 6. Any help is appreciated, I'm happy to provide more details/code if desired.
