Java: XA Transaction propagation within many threads

Question

How can I use a transaction manager (such as Bitronix, JBoss TS or Atomikos) in a Java SE (not Java EE or Spring) to support the following use case:

Let\'s assume we hav

Answer 1

XA Specification mandates that all XA calls be executed in the same thread context. To elaborate on the reason for this its because the commit could be called before any of the transactional branches are even created in your threads.

if you are just interested in how to execute those three calls in a XA transaction in JBoss TS

First make sure your -ds.xml specifies your datasource as an

InitialContext ctx = new InitialContext(parms);
UserTransaction ut = (UserTransaction) ctx.lookup("java:comp/UserTransaction");

ut.begin();

//Some Transactional Code

ut.commit();

Keep in mind with the code above you would not be able to use the ExecutorService to parallelize the calls.

Side Note: I don't know a lot about it but JTS/OTS claims to allow multiple threads to share in a transaction. I think it does this by propagating transactional context similar to ws-coordination/ws-transaction and is supported by JBossTS. Could be a red herring, but if your not under a time crunch it might be worth researching.
