Valentijn Scholten commented on JBAS-1443:
------------------------------------------

I think an extra interceptor could work out nicely, any hints on how to implement this interceptor? Is there an interceptor we could use or use as a good base? We would need some kind of waiting/signaling to implement this. I'm not into developing interceptors, so I'm not sure how to do this best?

> Weblogic has an allow-concurrent-calls proprietary tag for stateful session beans. The allow-concurrent-calls specifies whether a stateful session bean instance will allow concurrent method calls. The value of this element may be either "True" or "False". The default value is "False". When a stateful session bean instance is currently in a method call and another (concurrent) method call arrives on the server, the EJB specification requires that the server throw a RemoteException. By default, allow-concurrent-calls is false, and the EJB container will follow the EJB specification. When this value is set to true, the EJB container will block the concurrent method call and allow it to proceed when the previous call has completed.
