For simplest scenarios you will be fine with default simulated transactions. But if you're using multiple transactional resources then WebSphere's transaction manager is the way. Hibernate's approach (which is correct) is trying to utilize Websphere transaction manager - since there is no documentation on that, it is understandable developer frustration. :) Most of that feature was developed using trial/error approach :) http://ayende.com/4016/funny-comments#comment1http://ayende.com/4016/funny-comments#comment1Sat, 16 May 2009 09:54:07 GMT
