JBoss 5.1| NameNotFoundException when referencing EJB2 bean from @PostContruct applied method of EJB3
Our application uses ejb2.0 and ejb3.0. All ejb2 beans are packaged in app-ejb.jar and all ejb3 beans are packaged in app-ejb3.0.jar. These jar files (app-ejb.jar and app-ejb3.0.jar) are packaged in single EAR file i.e. application.ear. Our project currently uses JBoss 4.2.3 and now I am trying to migrate it to JBoss 5.1.
While deploying application.ear, I am getting javax.naming.NameNotFoundException:
14:47:23,046 ERROR [STDERR] javax.naming.NameNotFoundException: com.myrio.tm.docgen.UpdateRegistryHome not bound
14:47:23,046 ERROR [STDERR] at org.jnp.server.NamingServer.getBinding(NamingServer.java:771)

A) I found below lines in logs (appear before NameNotFoundException):
14:47:17,343 INFO [EjbDeployer] installing bean: ejb/totalmanage-ejb.jar#com.myrio.tm.docgen.UpdateRegistryHome,uid27736269
14:47:17,343 INFO [EjbDeployer] with dependencies:
14:47:17,343 INFO [EjbDeployer] and supplies:
14:47:17,343 INFO [EjbDeployer] jndi:com.myrio.tm.docgen.UpdateRegistryHome
B) And, below lines appear in logs after NameNotFoundException exception:
14:47:34,015 INFO [EjbModule] Deploying com.myrio.tm.docgen.UpdateRegistryHome
// logging for other beans
14:49:39,230 INFO [BaseLocalProxyFactory] Bound EJB LocalHome 'com.myrio.tm.docgen.UpdateRegistryHome' to jndi 'com.myrio.tm.docgen.UpdateRegistryHome'
C) EJB3 bean class is implemented like:
@Stateless(name = "DocumentBuilderBean")
public class DocumentBuilderBeanImpl implements DocumentBuilderBean {
private UpdateRegistry updateRegistry;
@PostConstruct
private void init() {
try {
InitialContext ic = new InitialContext();
UpdateRegistryHome home == (UpdateRegistryHome)ic.lookup("com.myrio.tm.docgen.UpdateRegistryHome");
updateRegistry = home.create();
}
catch (CreateException ex) {
logger.error("Error initializing update registry reference (create) ");
}
}
// other methods
}
[DocumentBuilderBean is local interface]
D) UpdateRegistryHome & UpdateRegistry interfaces are like:
=> public interface UpdateRegistryHome extends EJBLocalHome {
UpdateRegistry create() throws CreateException;
}
=> public interface UpdateRegistry extends EJBLocalObject {
// few methods
}
=> all required entries are there in ejb-jar.xml file
-----------------------------------------------------------------------------------------------------------------------------------------
The problem here is 'DocumentBuilderBean' is trying to lookup ejb2 bean (in @PostConstruct applied method 'init') which is still not bound to JNDI. If i remove ejb2 lookup from init method; everything works fine. No problem when running same ear on Jboss 4.2.3.
Can some one suggest me how to make sure 'DocumentBuilderBean' instance is created (and @PostConstruct method is invoked) only after ejb2 is successfully deployed and bound to jndi)?
Thanks
