[Guido Bening (JIRA)]

No pooling for stateless session beans
--------------------------------------

                 Key: EJBTHREE-653
                 URL: http://jira.jboss.com/jira/browse/EJBTHREE-653
             Project: EJB 3.0
          Issue Type: Bug
          Components: EJB3 Extensions
    Affects Versions: EJB 3.0 RC8 - FD
         Environment: OS: Windows XP SP2
JDK 1.5.0_06_b05
JBoss AS 4.0.4 GA
            Reporter: Guido Bening


Scenario:
Client VM calls a method on a EJB 2 Stateful Session Bean (SFSB) via the remote interface in a loop for 1000 times.Transaction starts on the application server. The SFSB method calls a method on a EJB3 Stateless Session Bean (SLSB) - via the remote interface (local interface makes no difference).

The print out in the PostConstruct callback method of the EJB3 SLSB shows us, that a new bean instance was created for each of the 1000 method calls. Because of ThreadLocal pooling approach, we print out the Thread id too to show, that we always have the same Thread for each method call.

CallBack method:
    /**
     * EJBCreate method.
     */
    @PostConstruct
    public void ejb3Create() {
        System.out.println("New SessionBean " + this);
        System.out.println("Thread " + Thread.currentThread().getId());
        setupBean();
    }
    
And the log for a few of the 1000 calls:
