Non-synchronized client method calls

Question

hi there,
i am having following scenario:
methods provided in the remote interface of a stateful session bean are called by a remote client.. client is using multithreading. now these methods in stateful session forward method calls to a stateless session and then an entity using local interfaces. the point here is that the client only has one object of the stateful session ( obviously an object per user session)
the problem is that when i call the methods on this object one by one it goes fine. but when in multithreaded client application one method is called by first thread and another by second at the same time, application crashes. and the server tells that client has tried to enter stateful session with different transaction context. does anybody have some idea to solve this problem without having the client to make synchronized calls.
thanx in advance,

Hi,
The Container serializes calls to stateful session beans.And hence your application calling in a multithreaded environment will surely fail.This is because the state of the bean might be corrupt when calls are concurrent.And different applications servers might provide some way of overriding this behaviour..Surely weblogic has got one way..
