------------------------------------------
I didnt get my screenshoty attached, so Im going to show the code here.
org.apache.openejb.core.stateful.StatefulContainer
Between lines 692-699
// Is the instance alreayd in use?
if (instance.isInUse()) {
// the bean is already being invoked; the only
reentrant/concurrent operations allowed are Session synchronization callbacks
Operation currentOperation = callContext.getCurrentOperation();
if (currentOperation != Operation.AFTER_COMPLETION &&
currentOperation != Operation.BEFORE_COMPLETION) {
throw new ApplicationException(new
RemoteException("Concurrent calls not allowed."));
}
}

> Key: OPENEJB-1099
> URL: https://issues.apache.org/jira/browse/OPENEJB-1099
> Project: OpenEJB
> Issue Type: Bug
> Components: container system
> Affects Versions: 3.1, 3.1.1, 3.1.2
> Reporter: David Blevins
> Fix For: 3.1.3
>
>
> A stateful bean should be able to invoke itself via its business interface.
> The following code should work:
> @Stateful
> public class MySessionBean implements MySessionBeanLocal {
> @Resource
> private SessionConext context;
> public void method1() {
> System.out.println("Method 1 invoked!");
> context.getBusinessObject(mySessionBeanLocal.class).method2();
> }
> public void method2() {
> System.out.println("Method 2 invoked!");
> }
> }
> Currently this results in the following exception:
> I get a "Concurrent calls not allowed" exception:
> javax.ejb.EJBException: The bean encountered a non-application exception;
> nested exception is:
> javax.ejb.EJBException: Concurrent calls not allowed
> at
