Issue while deploying EJB 3 with JBoss AS 7

[manoj.m.agarwal]

Hi,

I am trying to deploy a SLSB with  annotations @Singleton and @Startup. I packaged it as a jar and put it under standalone/deployments.

I get this error while starting server. Any help will be very helpful.

11:35:22,844 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-4) MSC00001: Failed to start service jboss.deployment.unit."xyz-startup-bean-3.0.0-SNAPSHOT.jar".POST_MODULE: org.jboss.msc.service.StartException in service jboss.deployment.unit."xyz-startup-bean-3.0.0-SNAPSHOT.jar".POST_MODULE: Failed to process phase POST_MODULE of deployment "xyz-startup-bean-3.0.0-SNAPSHOT.jar"

Does your deployment contain OSGI manifests?

[manoj.m.agarwal]

No...it doesn't. If it needs to have OSGI then please let me know how to do it because i am not much aware of it.

Thanks !

Can you show us the code of the bean?

You're using any xml files in you deployment unit?

Show us a jar -tvf xyz-startup-bean-3.0.0-SNAPSHOT.jar.

Hi Frank,

I was following another thread where you suggested EJB option for invoking something while JBoss startup .(https://community.jboss.org/thread/201070)

Jaikiran made a correction in your suggestion, and now this error is gone but another issue is surfaced.....

Now my jar is getting deployed but init method(annotated with @PostConstruct) is not getting invoke.

This is my bean class...

  package com.abc.xyz;
 
  import javax.annotation.PostConstruct;
  import javax.ejb.Startup;
  import javax.inject.Singleton;
 
  @Singleton
  @Startup
  public class xyzStartupBean
  {

      public xyzStartupBean()
      {
          System.out.println("bean instance created");
        
      }
 
      @PostConstruct
      public void init()
      {
          System.out.println("post construct....");
      }
}

Attached is the output of jar-tvf .................

In ejb-jar.xml i have just <display-name> and MANIFEST.MF have just version.

Please let me know if i need to do some explicit configuration, so that init() get invoke while JBoss startup.

Thanks !

import javax.inject.Singleton;

Wrong import! It should be javax.ejb.Singleton.

[manoj.m.agarwal]

Hi Jaikiran,

I corrected the import stmnt...now i am ending up with the same exception what i posted in the starting of this thread

[dmlloyd]

A NullPointerException is always a bug.  That said, it would be helpful if you could open a JIRA at http://issues.jboss.org/browse/AS7 containing the stack trace and an EJB JAR which reproduces the issue, along with the corresponding source code.

Thanks!

[manoj.m.agarwal]

I opened a JIRA bug for it.

Thanks David
