Please do let me know when you have JTS enabled. I am pretty positive you will need to use the CORBA names for the EJB.

If you have a scenario where you do not have transactional resources in AS 1 _and_ 2, the quickest way to coordinate a transaction at AS2 would be to add a new EJB on AS2 with @REQUIRES and that performs the coordination of the EJBs for you. It should perform better as you won't have a chatty exchange to coordinate the transaction between the two servers, just a single invocation. To be clear, do you have transactional resources that are required in the same transaction at both servers?

I was asking if there are transactional resources at the local server too.

I tried your app but it seems to assume that there is a second server running and I am not positive how to run two AS5 instances on the same box. To be honest when it comes to AS questions like that you are better asking them on the AS list.

What we can help with is configuring JTS, but from the sounds of your app you would be much better:

1. Create a new session bean that does most of your servlets logic, mark it as @REQUIRES

2. Deploy it on server 2

3. Call this EJB from the servlet in server1, don't do transaction demarcation here, it should be all done in the new EJB

I grepped the internet a lot looking for an answer for you, you could ask the person here: [jboss-as7-dev] UserTransaction used by remote clients who seems to know how this used to be done, but I suspect it was truly remote clients and not remote application servers?

To help understand why I can't help too much, you are in the forum for the Transaction Manager (2PC engine), a lot of the questions are are asking are more related to EJB and the AS integration with the Transaction Manager so they are better asked in the AS forum. Unfortunately the application server you are using I am not sure if it is supported in the community any more. It looks like this is where you would ask the question "how do I resolve a usertransaction from a different JBoss server in JBoss 5.1.2": JBoss AS

Please do let me know how you get on, particularly I would like to know if you are able to introduce the new EJB, alternatively if you have questions on enabling JTS I am sure we can try to answer those as Mike pointed you out a great article he wrote on that one.

Great, well JTS should make this work too, I just think it could perform better with that remote EJB as you won't have two round trips to server 2.

Let me know how you get on with enabling JTS and hopefully it is plain sailing once it is enabled
