Exception on Timer EJB

[arun168403]

I have a SLSB as below which implements Timer interface:

public class EzSetupEJB
        implements javax.ejb.SessionBean
         
{
  …….
  ….

  @Resource
  private TimerService timerService;

  public void onDeployment()
  {
  s_log.info("STARTUP SEQUENCE INVOKED");
   createTimer(1000, EzSetupTimerInfo.STATE_CREATENE, null);
  }
  protected void createTimer(long expiration, int ezSetupState,
   String userLabel)
  {
  s_log.info("CreateTimer invoked!");
  Timer t = timerService.createTimer(expiration,new String(""+ezSetupState));  
  
  }
  @Timeout
  @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
  public void checkStatus(Timer timer)
  {
   ……
  }


}

I’m trying to invoke the onDeployment() method from a remote client to initiate the timer. But I’m getting an exception as below:

Could you kindly help on this:

What does your calling code look like and how is that EzSetupEJB configured as a EJB?

Also, please try this against a later released version of JBoss AS7 or WildFly Downloads and see if it was a bug which might already have been fixed.

Hi Jaikiran,

yes.. my client is calling this as an EJB.

final Hashtable jndiProperties = new Hashtable();
  jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory" );
  jndiProperties.put("jboss.naming.client.ejb.context", true);
  jndiProperties.put(Context.PROVIDER_URL, "remote://localhost:4447");
 jndiProperties.put(Context.SECURITY_PRINCIPAL, "arun");
 jndiProperties.put(Context.SECURITY_CREDENTIALS, "arun123");
 Context context = new InitialContext(jndiProperties);
 String jndi ="gem/ejb-jar-ezsetup/EzSetup!com.alcatel.gem.ezsetup.interfaces.EzSetup";
 EzSetup obj1 = (EzSetup)context.lookup(jndi);
 obj1.onDeployment();

I'm using JBoss7.1.1 Final Version for development.

I tried to deploy on the 8.0.0 Alpha4. My CMP Beans are not deployed in the server.

It stops deplyment with error "JBAS014588: CMP Entity Beans are not supported".

Thanks,

Arun

Support for EJB2 EntityBeans is removed from WildFly as it is marked as optional within the EJB specification for EE7.

The latest version where EJB2/CMP is supported will be AS7 and EAP6.

[arun168403]

thanks for the suggestion.

I have replaced the logic with wait().
