Porting WLS8.1 to JBoss5 - JNDI lookup for XA factory return

[lwalter]

G'day,

This is probably a newbie question, but I couldn't find the answer in a few days of Googling. I'm trying to port a JMS-using app from Weblogic 8.1 to JBoss 5.0.

I've configured a transactional JMS factory like this in jms-ds.xml:

<tx-connection-factory>
 <jndi-name>applications/ig/jms/INVOICE_GENERATOR_CF</jndi-name>
 <use-java-context>false</use-java-context>
 <xa-transaction/>
 <rar-name>jms-ra.rar</rar-name>
..etc..

This is then set up in connection-factories.xml:

<mbean code="org.jboss.jms.server.connectionfactory.ConnectionFactory"
 name="jboss.messaging.connectionfactory:service=ConnectionFactory"
 xmbean-dd="xmdesc/ConnectionFactory-xmbean.xml">
 <depends optional-attribute-name="ServerPeer">jboss.messaging:service=ServerPeer</depends>
 <depends optional-attribute-name="Connector">jboss.messaging:service=Connector,transport=bisocket</depends>
 <depends>jboss.messaging:service=PostOffice</depends>

 <attribute name="JNDIBindings">
 <bindings>
 <binding>/ConnectionFactory</binding>
 <binding>/XAConnectionFactory</binding>
 <binding>java:/ConnectionFactory</binding>
 <binding>java:/XAConnectionFactory</binding>
 <binding>applications/ig/jms/INVOICE_GENERATOR_CF</binding>
..etc..

The JNDI View mbean then shows me this bound into the global namespace:

+- applications (class: org.jnp.interfaces.NamingContext)
 | +- ig (class: org.jnp.interfaces.NamingContext)
 | | +- jms (class: org.jnp.interfaces.NamingContext)
 | | | +- INVOICE_GENERATOR_CF (class: org.jboss.resource.adapter.jms.JmsConnectionFactoryImpl)

So when the code does this:

Object temp = context.lookup(jndiFactoryName);
if (temp instanceof XAQueueConnectionFactory) {
 factory = (XAQueueConnectionFactory) temp;
}
else {
 log.error("getXAQueueConnectionFactory: Could not cast the object " + temp.toString() + "to a XAQueueConnectionFactory class.");
}

Sure enough, it logs this:

2009-04-28 16:01:27,226 ERROR [au.com.soul.common.utils.servicelocator.ServiceLocator] getXAQueueConnectionFactory: Could not cast the object org.jboss.resource.adapter.jms.JmsConnectionFactoryImpl@665e81to a XAQueueConnectionFactory class.

Could someone please point me in the right direction?

thanks in advance,
Len

Sorry, that subject should read "Porting WLS8.1 to JBoss5 - JNDI lookup for XA factory returns wrong class"

Hi ,

jms-ds.xml is for JCA use. If you use JCA, then use the JCA API. You can't cast it to JBM connection factory.

To get a JBM connection factory, you need to configure the connection-factories-service.xml. It's under deploy/messaging, take a look and you will know it.

Thanks for the quick response. I was under the impression I needed JCA for transactional JMS. I've removed the tx-connection-factory and now the code snippet I posted works.

However.. I now get an error like this:

2009-04-30 19:15:11,619 ERROR [org.jboss.messaging.util.ExceptionUtil] ConnectionEndpoint[h3-67tn85uf-1-hjjm85uf-wxb1yo-f1rp1a] sendTransaction [w7-rezp85uf-1-hjjm85uf-wxb1yo-f1rp1a]

Is this still a JMS problem or should I be asking in the JTA forum?

Thanks heaps,
Len

Perhaps I should ask a different question - where's a good place to find doco that might help out here? I'm not a J2EE expert either (in case it wasn't obvious!) so perhaps I need to learn some more general stuff about that to solve these kind of problems.

[gaohoward]

Have you downloaded and read the AS documents from jboss.org? It should be a good thing to start with.

[lwalter]

I've read the config & admin document for AS, the JBM doco and the JTM doco. However I wasn't able to find any solutions.

NB that this code works fine in Weblogic 8.1, so you could classify this as a migration problem.
