Can you describe this "basic stuff" a little? I am considering implementing distributed tx.

this is a better example)
In the 3.x series of JBoss, there isn't a way to have one SSB with a
transaction attribute of Required call another SSB with a transaction
attribute of Required on a second jboss instance and have both of those
beans enlist in any kind of "native" JBoss transaction. If you stay within
one instance of JBoss, you are fine, but the moment you start to really do
n-tier designs with tight transaction integration (ie XA), that is when
problems arise with this NotSerializable exception. I do know that the 3.x
series only supports local transaction, but my overall point is that I just
don't understand why a distributed transaction has not been a "native"
feature of JBoss from the beginning being that it seems to me that it would
be fundamental to n-tier designs. I presume there is a good reason for
this. I just don't know/see what that reason would be.
the only reason is that no one has previously written a distributed tx manager. I wrote the basic stuff we need in jboss 4, it should even work with the trunk invoker.
