Scott M Stark commented on JBAS-1443:
-------------------------------------
This should simply require adding a jboss.xml setting that set a
allowConcurrentCalls to true when enabled and to update the
org.jboss.ejb.plugins.StatefulSessionInstanceInterceptor invoke method to only
impose the concurrency check if requested:
if ( allowConcurrentCalls == false && isCallAllowed(mi) == false )
{
// Concurent calls are not allowed
throw new EJBException("Application Error: no concurrent " +
"calls on stateful beans");
}
else
{
ctx.lock();
}
> Add a flag to allow concurrent calls on stateful session beans

> URL: http://jira.jboss.com/jira/browse/JBAS-1443
> Project: JBoss Application Server
> Type: Feature Request
> Components: EJBs
> Versions: JBossAS-4.0.1 Final, JBossAS-3.2.7 Final
> Reporter: Scott M Stark

> 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.
