   Perhaps I wasn't clear enough. My point is that it is a bad idea to mix 
usage of JTA interface with declarative container managed transacttions for 
EJBs. In other words it is probably to use Spring JTA helpers/wrappers in web 
layer which is not using EJB's.

   Anyway it would be good have some more advanced tests to ensure that JTA 
actually work in WLS8 (and other containers) in case of failure/rollback with 
multiple XA resources involved into transaction (especially resources from 
different vendors, such as Oracle, Sybase, MQSeries).
