Transaction handling between two remote jboss eap 6.2 servers

[abajwa]

All,

I need to know whether starting a transaction on node1 and then doing work on node 2 with remote ejb calls from node 1 wrapped under a UserTransaction is possible or not. As of now What Im seeing is below.

Below is the use case Im testing.

1) CMT on an EJB hosted on server1(jboss eap 62)

2) Samplw WebApp deployed on server2  with a servlet doing remote lookup on server1 and executing the remote calls under a transaction and once all work done then commit else rollback

I see the below exception when the commit is fired.

Attaching the source project for both, please let me know why is it not able to find the EjbReceiver when the ejbs call goes through fine and executes the remote call.

Url for testing if you run the app is http://localhost:8180/EjbClientWebApp/EjbClientSrvlt?action=true where action true or false controls the commit or rollback.

One  observation is that even when hosted on same server the approach of EjbClient.getTransaction doesnot work , then when i do the lookup of the transaction object old way through jndi, it works on same server but the actual use case fails when we move again to remote servers.

    //ut = EJBClient.getUserTransaction("myjvmserver");

     ut = (UserTransaction) ctx.lookup("java:jboss/UserTransaction");

In jboss 5 i had to enable JTS for this to work and now even with JTS enabled i am not able to get this working.

Would appreciate some help on this.

Got this working without JTS but looks like Ejb Security is a requirement without which the transaction propagation does not work, had to make the ejb mandatory to confirm transaction propagation was not happening, then went on to enable the security based on the knowledge base articles and got the transactions to get propagated.

Can any one please confirm my findings that security is a must when talking about transactions between two remote servers, its not new as weblogic too enforces intra domain security for this to work but need to be sure before finalizing the solution.

Also I used the client configuration of

Configuring remote servers in the JBoss profile

Can some also please point to how we can do this for a cluster for faiover.
