[jboss-user] [EJB 3.0] - MyEclipse5.5.1GA+JBOSS4.2.1GA+EJB3, very strange problem?????

for a new project i met following strange problem,please help me : using myeclipse to generate a EJB3 projects and When I create a session bean and use the annotation "@PersistenceContext" to inject the EntityManager, then I deploy such EJB3 to jboss. With jboss web-console ,in JNDIView I cann't find the EJB's JNDI name ,that mean the session bean cann't bind to a JNDI name abd I cann't visit it. But when I delete the using of the annotation "@PersistenceContext", the session bean will be deployed ok, in jboss web- console I can also find the session-bean's JNDI name. code like : //deploy it will have problem @Stateless public class CommonNativeQuery implements CommonNativeQueryLocal, CommonNativeQueryRemote { @PersistenceContext EntityManager em; } //deploy it will be OK @Stateless public class CommonNativeQuery implements CommonNativeQueryLocal, CommonNativeQueryRemote { //@PersistenceContext EntityManager em; } In such circumstance, I cann't use EntityManager to operate the Entity-Bean ,it's really big headache,please help me!! thanks!!
