Help with HA Remoting with JBoss

[jgamache]

I've looked over all the remoting examples and they make sense to me and run no problems. I'm trying to use the "detection" examples that use JNDI. However, I need to use the HA-JNDI instance from with JBoss (4.2.2). I have an MBean, so what do I do? Do I
add the defined instance of HAJNDI as an attribute to my MBean? If so,
does it merely replace the JNDIDetector? Or both the JNDIDetector as
well as the MBeanServer (as the HAJNDI instance must already be
registered as an MBean...)

I think I am creating the JNDIDetector in the standard way, but how do I get it (on the client side obviously) to use the HA-JNDI instance in jboss? Here is the code I have:

// jndi detector will detect new network registries that come online
JNDIDetector detector = new JNDIDetector(getConfiguration());
// set config info for detector and start it.
detector.setPort(detectorPort);
detector.setHost(detectorHost);
detector.setContextFactory(contextFactory);
detector.setURLPackage(urlPackage);


server.registerMBean(detector, new ObjectName("remoting:type=JNDIDetector"));
detector.start();

thanks for any help

Well, I've never tried to do what you're asking about, but it looks like it's just a matter of telling JNDIDetector which URL to connect to so that it gets an InitialContext from HA-JNDI instead of JNDI. In particular, JNDIDetector.createContext() does this:

 env.put(Context.PROVIDER_URL, host + ":" + port);

so in your code you want

detector.setPort(1100);

where 1100 is the default port for HA-JNDI, as you can see in the "jboss:service=HAJNDI" MBean in $JBOSS_HOME/server/all/deploy/cluster-service.xml. For more about HA-JNDI, see section "14. Clustered JNDI Services" in the AS documentation: http://www.jboss.org/file-access/default/members/jbossas/freezone/docs/Server_Configuration_Guide/4/html/index.html.

Let me know how it goes.
