I am using the JBoss 4.1 version to test the clusteing my EJB components. I am pleasently surprised to see most of the things working out of the box(Infact at times i doubt whether i am seeing the right thing).
My concern is whether JBoss supports the concept of idempotency. Currently, i have clustered a stateful session bean and the moment i crash one instance (say CTRL-C) the other instance picks up the invocation, start from scratch and completes the invocation (without returning a RemoteException to the client). Now the issue is if the CTRL-C was done just after the bean had completed its operation (including the DB activity) and before it was replying back to the client the other instance re-executes the invocation which would mean redoing the activity twice. My expectation was that it will re-execute if it is marked as idempotent only. Is JBoss marking all the methods as idempotent by default. If yes then how to configure it otherwise. The second issue is that i have a stateful session bean. Now the failover for this bean is executing without me specifying the state replication mechanism in the jboss.xml (regarding the /HASessionState/Default). Additionally, i was trying to check the failover when the call is inside a method (for which i have induced SLEEP within the method). To test the same i disconnected the network cable (to simulate network failure) from the instance where the call was being serviced and the client endlessly waited for something to happen, can someone tell me how to specify the SFSB timeout for the client so that it doesn't wait endlessly.
