[jboss-jira] [JBoss JIRA] Created: (EJBTHREE-653) No pooling for stateless session beans
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:
