Hi,
executing
if (System.getSecurityManager() == null) {
| System.setSecurityManager(new
RMISecurityManager());
| }
| Hashtable env = new Hashtable();
| String factory =
"org.jnp.interfaces.NamingContextFactory";
| env.put(Context.INITIAL_CONTEXT_FACTORY, factory);
| String url1 = "jnp://localhost:1099";
| env.put(Context.PROVIDER_URL, url1);
| Context ctx = new InitialContext(env);
| MBeanServerConnection mconn =
(MBeanServerConnection)ctx.lookup("jmx/invoker/RMIAdaptor");
| ObjectName name = new
ObjectName("jboss.jca:name=ds/DefaultDS,service=ManagedConnectionPool");
| Object val = mconn.getAttribute(name, "InUseConnectionCount");
| System.out.println(name + "\n\tInUseConnectionCount=" + val);
leads to:
anonymous wrote : javax.management.InstanceNotFoundException:
jboss.jca:name=ds/DefaultDS,service=ManagedConnectionPool is not registered.

I'm not sure I made myself quite clear on what i want to do. I want to obtain a
reference to a Bean of my own, deployed in JBoss named WorldMBean which extends
the interface World.
What exactly are the lines
ObjectName name = new
ObjectName("jboss.jca:name=ds/DefaultDS,service=ManagedConnectionPool");
| Object val = mconn.getAttribute(name, "InUseConnectionCount");
| System.out.println(name + "\n\tInUseConnectionCount=" + val);
supposed to do?
I was originally trying to adapt the code found in the trail at:
http://trailblazer.demo.jboss.com/EJB3Trail/serviceobjects/jmx/code/calculator.jsp.html
only I'm using a java client not a jsp. I'm not sure if the code in the jsp is
only supposed to work locally because of:
MBeanServer server = MBeanServerLocator.locate();
If so is there a simple way to get a reference to my MBeanServer on the same
machine but not in the same VM?
Thanks for your help

Using Tomcat but need to do more? Need to support web services, security?
