Transactional Context Propagation between WLS and JBoss

[a.gazzarini]

Hi, I've installed JBossTS onto my JBoss 4.0.5GA installation.
I'm trying to propagate a transaction started from an EJB running into WebLogic 8.1 to an EJB running into JBoss.

- the EJB on WLS is a simple stateless session bean. It has one method with "Required" as transaction attribute. It calls the ejb on jboss using the following properties :

Context.INITIAL_FACTORY = org.jnp.interfaces.NamingContextFactory
Context.PROVIDER_URL = jnp://127.0.0.1:1099
Context.URL_PKG_PREFIXES = org.jboss.naming rg.jnp.interfaces

- The ejb on JBoss is another simple stateless session bean. It has one method that simply invokes the sessionContext.setRollbackOnly(); This method has "Mandatory" as transaction attribute.

Well, when the call happens the ejb on JBoss tells me that "it's not possible to call this method WITHOUT a transaction!".

What's wrong?

Thanks in advance...

Andrea

Which version of OTS is WebLogic 8.1 using? You'll need to check that it will accept and recognise an OTS PropagationContext.

[a.gazzarini]

I've reproduced the scenario above on two jboss instances (running over two different machines)...
The transaction still isn't propagated...the installation of jboss is the same (I copied the JBoss installation folder on the second machine) and obviuosly the configuration of the JBossTS is the same too.
In this way I'd be sure that the 2 servers are running the same OTS version...right?

Last thing : the first ejb (machine A) is doing the lookup of the second ejb (machine B) using

com.sun.jndi.cosnaming.CNCtxFactory as INITIAL CONTEXT FACTORY
and
corbaloc::192.168.1.34:3528/NameService as PROVIDER URL

The call to the second ejb fails and the calling instance of JBoss logs :

What value are you using for com.arjuna.ats.jts.alwaysPropagateContext and what is the contents of the iiop-service.xml file?

[a.gazzarini]

com.arjuna.ats.jts.alwaysPropagateContext is set to "YES"

and the content of iiop-service.xml follows:

still here...the reported configuration is the same for both jboss instances...

Thanks

Hmm, looks reasonable. email me your test case and I'll take a look when I get time.

looks strange. It would imply that your server is not using JacORB but is in fact using the Sun ORB.

Thank you very much...Could you please give me your mail (otherwise mail me an empty message).

Thanks for reply but writing the following into the iiop-service.xml is not sufficient to tell to jboss to use the JacOrb ORB?

org.jacorb.orb.ORB
org.jboss.system.ORBSingleton
org.jacorb.orb.ORBSingleton

[a.gazzarini]

excuse me again...I'm tired...the properties are:

<attribute name="ORBClass">org.jacorb.orb.ORB</attribute>
 <attribute name="ORBSingletonClass">org.jboss.system.ORBSingleton</attribute>
 <attribute name="ORBSingletonDelegate">org.jacorb.orb.ORBSingleton</attribute>

Thanks..

[a.gazzarini]

Mark, your post is the only possible answer to my problem because in the WebLogic documentation I've read that in the WebLogic-to-Sun JDK ORB communication scenario there's no propagation of transaction (I suppose the reason is that SUN ORB impl is limited)
However, the first lines of previous posted stack trace say:

16:12:24,093 ERROR [STDERR] at org.jacorb.orb.SystemExceptionHelper.read(SystemExceptionHelper.java:173)
16:12:24,093 ERROR [STDERR] at org.jacorb.orb.ReplyReceiver.getReply(ReplyReceiver.java:326)

16:12:24,093 ERROR [STDERR] at org.jboss.proxy.ejb.DynamicIIOPStub.invoke(DynamicIIOPStub.java:125)

and they indicates to me that jacorb is doing something inside this call...
Just to remember...this is a JBoss-to-JBoss scenario but I having the same result in the WebLogic-to-JBoss scenario.

Just to tell the whole story : my real need is to use WebLogic Integration (WLI) to coordinate in a transactional way several EJB exposed on jboss and other resources exposed elsewhere....
So I need to start a transaction from the Business Process Manager (WLI) and propagate it to the called resources.

Thanks for support...

[marklittle]

Well let's see if we can get your JBoss-to-JBoss scenario working first. I need to check: is your alwaysPropagate option set to true in the JBossTS configuration file? If not, you either need to change it or use our RMIC generator on your exposed beans. The reason for this is that OTS 1.1 (JTS 1.1) only propagates a transaction if the destination object inherits from CosTransactions::TransactionalObject, which no Java code ever will by default! So yo need to override the default behaviour (using the config option or the tool). Go with the config option for now IMO.

Mark - read the previous page.
