Questions about the JBTS implementation of this functionnality Q'1: Is there documentation about this topic, or examples specific to JBossTS? I couldn't find a lot in the project documentation (the JTS Programmer Guide). Q'2: Can i continue to use my Spring declarative transactions, with JBTS embedded as the JTA transaction manager? Q'3: In relation to the previous post, do async services need to be one-way to be able to participate in a multi-threaded transaction? Q'4: Would this work with JBossPOJOCache as the transactional resource? (i'm not using a database) Q'5: Any gotchas and things that aren't possible that you can think of?
