if that's the ws transaction spec, I don't think we support it.  My  
impression is that web services are usually used for integration  
scenarios where response time is not a major factor and long reply  
latencies are expected.  This is not usually something you want to  
hold a transaction open for.  I would investigate (transactional) jms  
to allow your local transactions to complete quickly and allow the web  
service processing to proceed at leisure.
