I am trying to access the RMIAdaptor on a remote jboss server running 4.0.4.
from a different 4.0.4 jboss server using the following code.
import java.util.Hashtable;
import java.util.Iterator;
import java.util.Set;
import javax.management.MBeanServerConnection;
import javax.management.ObjectName;
import javax.naming.Context;
import javax.naming.InitialContext;
import org.jboss.jmx.adaptor.rmi.RMIAdaptor;
public class MBeanTester {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
try{
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "jnp://localhost:1099");
InitialContext ic = new InitialContext(env);
RMIAdaptor server = (RMIAdaptor)
ic.lookup("jmx/invoker/RMIAdaptor");
Set name_set = null;
ObjectName on = null;
name_set = server.queryNames(new
ObjectName("jboss.jca:service=ManagedConnectionPool,*"), null);
if(name_set.isEmpty())
System.out.println("no pools returned");
for (Iterator it = name_set.iterator(); it.hasNext() ; ) {
on = (ObjectName)it.next();
String pool_name = on.toString();
String status = server.getAttribute(on,
"State").toString();
System.out.println("Pool Name: " + pool_name +
" , " + status);
}// end for
}catch(Exception e){
e.printStackTrace();
}
//testConnectionList("1099", "localhost");
}
}
When I run the app I am getting the following exception.

I when I change the code to cast the returned lookup value as a plain old
Object I get the same error message. Which does not make sense since everything
should be able to be casted to the raw Object type.
However, when I take out the env hashmap and do a local lookup the code works
fine.
InitialContext ic = new InitialContext();
RMIAdaptor server = (RMIAdaptor)
ic.lookup("jmx/invoker/RMIAdaptor");
There is somthing not working with a remote lookup.
Does anyone know if I do not have something on jboss configured correctly or
what the problem is?
