I'd like to ask a question about using an xa-datasource defined within my AS7 instance. *What I did:* I defined two different xa-datasources pointing to two databases *What I need:* I need to implement a two phase commit using those two xa-datasources mentioned above. Is there any Java sample/example how to use the JBoss transactional mechanism to do what I need? As I understood, I can (I have to) use an ordinary DataSource instead of XADataSource in my code, right? How does it work? What is the right way to do following: 1. Create two connections to 2 different DBs (using xa-datasources defined within my AS7) 2. Do some operations over both of them 3. Do a final commit (or rollback if any error) Last question - what's the role of the JBoss's TransactionManager? How does it work? Is it hidden for the developers or do we need to instantiate it explicitly? Since I didn't found any sufficient answer I appreciate any explanation and help! Thanks a lot, Bobo -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/780509#780509] Start a new discussion in JBoss AS 7 Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
