ServiceContext in OperationContext does not match error

[Igor Nogueira]

Hello guys!
 I get the "ServiceContext in OperationContext does not match" error this
error when I try to do this:

I have 2 webservices: Service A and B. All the invocations are sent to
service A. So, service A has the actual state in it's session.
Then I serialize the MessageContext in A and send it as a string to  service
B. In B, I rebuild MessageContext, activate it and try to set B's context. I
do this on the following piece of code:

           ByteArrayInputStream bios = new
ByteArrayInputStream(decode.decodeBuffer(teste));
           ObjectInputStream ois = new ObjectInputStream(bios);
           MessageContext state = (MessageContext)ois.readObject();
           state.activate(
MessageContext.getCurrentMessageContext().getConfigurationContext());
           //Setting Service B content

MessageContext.getCurrentMessageContext().setOperationContext(state.getOperationContext());

MessageContext.getCurrentMessageContext().setServiceContext(state.getServiceContext());

I'm using Application scope, and the information I try to retrieve is saved
on ServiceContext. The last operation gives me the error I mentioned before.
Is there something else I can do in order to fix it?

Thanks in advance,
