We need to talk about this...
If the client is standalone and using UserTx, then all the calls in one
tx MUST go to the same jboss server, since the client tm doesn't
handle 2pc distributed tx or much of anything-- just committing one
branch. In other words, you probably shouldn't be using UT on the
client with clustering at the moment. Is there some way to make this
sticky? If the server fails, I guess an exception should be thrown on
the client and the client should know enough to start the tx over??
If the client is a jboss instance, then this should be looking for the
real jboss tm on that server. This is not yet implemented as I recall.
Comments?
thanks

Hello,
The code for TransactionInterceptor (client side) in HEAD does this at
one
point (in the invoke):
transactionManagerServiceName =
new ObjectName (DEFAULT_CLIENT_TM_NAME_STUB) +
invoker.getServerID().toObjectNameClause());
In the standard scenario, that is fine, but in the clustering case,
what do
you expect invoker.getServerID() will return? This is problematic
because
when the invocation goes through the interceptor, we still cannot say
which
will be the target server (it is elected in the ... invoker itself!
