Accessing an MBean using RMIClientConnectorImpl

Hello,

Despite the fact this topic has been posted long time back - I have to broach upon the subject once again, since I have to know the correct way of doing things.

I'm trying to connect the MBean in the JBOSS server(version 2.4.4) via a client ant task and I'm using the following code snippet:
--------------------------------------
Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
props.put(Context.PROVIDER_URL, "jnp://localhost:1099");
InitialContext ctx = new InitialContext(props);;
String jndiName = "jmx:ranaa:rmi";

String jndiEntry = (String)ctx.lookup(jndiName);
..... JMXConnector server = new RMIClientConnectorImpl(jndiEntry);
---------------------------------------

However I'm getting the following error:

[ejbBatchTask] java.lang.ClassCastException:
org.jboss.jmx.server.RMIConnectorImpl_Stub
[ejbBatchTask] at tool.task.EJBBatchTask.execute(EJBBatchTask.java:99)
[ejbBatchTask] at

[ejbBatchTask] at org.apache.tools.ant.Target.execute(Target.java:309)
[ejbBatchTask] at org.apache.tools.ant.Target.performTasks(Target.java:336

Any idea why I'm getting this exception.

Thanks in advance!!!

Regards,

Rana

I found a solution to this.

I'm using RMIConnector to connect to MBeanServer with the code as follows:

Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
props.put(Context.PROVIDER_URL, "localhost:1099");
InitialContext ctx = new InitialContext(props);
String serverName = InetAddress.getLocalHost().getHostName();
String connectorName = "jmx:" + serverName + ":rmi";

_server = (RMIConnector)ctx.lookup(connectorName);

This code is working fine for me. So please consider this thread as closed.
