NotSerializableException when transferring state
I have a cluster with two nodes. They both export a HA-RMI stub:
rmiserver = (HARMIHelloWorld) haRMIServer.createHAStub(new RoundRobin());
haJndiContext.bind("HAHelloWorldServer",rmiserver);
It all works fine (fail over, round robin, etc..) but every time they try to transfer their state one to each other, the following error occurs:
12:25:09,543 ERROR [HipimePartition] GetState failed

The HARMIHelloWorldImpl implements Serializable.
Any idea?
Thanx in advance
