JMX Access from one Jboss instance to another

[avrahamr]

Hello,

I'm trying to access a Remote MBean Server from within a We application. Here my code (inside servlet, or JSP):

Hashtable environment = new Hashtable();
environment.put("java.naming.provider.url","jnp://tlvl2k376:1099");
InitialContext ctx = new InitialContext(environment);
MBeanServerConnection server = (MBeanServerConnection) ctx.lookup("jmx/invoker/RMIAdaptor");
ObjectName serverInfo = new ObjectName("jboss.system:type=ServerInfo");

String hostName = (String) server.getAttribute(serverInfo, "HostName");
System.out.println("Host: " + hostName);

On JBoss 4.0.1sp1 I'm getting the local host instead of the remote host as the answer. But if the other server is down, I get an exception. So the JNDI lookup is working.

On JBoss 4.0.0 we get the correct answer.

Any clues? Is there something I can do to make this work on 4.0.1sp1?

Thanks

Yes there was a problem introduced around 4.0.1.

http://jira.jboss.com/jira/browse/JBAS-1442

A couple of work arounds are mentioned in the issue and related issues and the fix is included in JBoss 4.0.2 (Which looks like it has just two outstanding issues left before it can be released).

Workaround 2: Use a different MBean name for the service, e.g. if it is an EJB
use a different jndi name or in the RMIAdaptor case, just change the name in
the config file

I didn't understand this workaround. My problem is with RMIAdaptor. Can you give an example?

Thanks
