Thanks for your reply gaohoward. I modified the code as you indicated: | Properties props = new Properties(); | props.setProperty(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory"); | props.setProperty(Context.PROVIDER_URL,"jnp://10.4.164.105:11099"); | | | | props.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces"); | | | Context ctx = new InitialContext(props); | | | ConnectionFactory factory = (ConnectionFactory)ctx.lookup("IVTCF"); | | System.out.println("looked up 'IVTCF' javax.jms.ConnectionFactory established! 'factory'=["+ | factory+ | "]"); | | But I still only get 'factory' values == NULL after executing the lookup(). Via the JBoss admin console, I checked the value for 'IVTCF' in the JNDI global namespace and it shows a correct and expected value. Global JNDI Namespace | | | +- IVTCF (class: com.ibm.mq.connector.outbound.ConnectionFactoryImpl) | I guess in the worst case, I could code this Producer to directly invoke the WS MQ implementation of com.ibm.msg.client.jms.JmsConnectionFactory, but I was hoping I could just deploy the WS MQ JCA Resource adapter to my JBoss instance, config a Resource-->ConnectionFactory via the JBoss admin console, and then just do a 'lookup' on that ConnFactory to have all the plumbing (from JBoss to WS MQ) done for me transparently (via JCA). Hoping to avoid coding directly to com.ibm.msg.client.jms.* API, do you have any other ideas/recommendations on how I might be able to get this to work via JBoss/JCA?
