[jboss-user] [JBossCache] - JBossCache standalone with JBossTM

JBossCache 1.4.1.SP3
JBossTM 4.2.3.SP5

I am having trouble getting transaction support working.

I have made the following transaction lookup class, 

public class JBossTMTransactionManagerLookup implements TransactionManagerLookup {
  | 
  |     public TransactionManager getTransactionManager() throws Exception {
  |         return com.arjuna.ats.jta.TransactionManager.transactionManager();
  |     }
  | 
  | }

and configured it in the treecache xml file:


  | ...
  | <attribute name="TransactionManagerLookupClass">....JBossTMTransactionManagerLookup</attribute>
  | ...
  | 

Then, I create transactions like this:


  |         UserTransaction tx = com.arjuna.ats.jta.UserTransaction.userTransaction();
  |         
  |         tx.begin();
  |         // cache get/put operations:
  |         tx.commit();
  | 

This does not work.  The TransactionManagerLookup class is never called.  Furthermore, if it is called, I don't understand how JBossCache determines if there is a transaction open it can participate in.  Does it lookup it's transaction manager and ask if there are any open transactions in the current Thread, or something like that?
