hi i am new for JBoss - JMX.
Can any one tell, how can i access the Instance of JBoss MBeanServer .

i try with below code.

Properties = new Properties();
Properties.put("java.naming.factory.initial", "org.jboss.naming.HttpNamingContextFactory");
Properties.put("java.naming.provider.url", "http://localhost:8080/invoker/JNDIFactory");
Properties.put("java.naming.factory.url.pkgs", "org.jboss.naming.client");

InitialContext ctx = new InitialContext(Properties); // From jndi.properties
server = (MBeanServerConnection) ctx.lookup("jmx/invoker/HttpAdaptor");
try {
ObjectName name = new ObjectName("jboss.system:type=Server");
try {
MBeanInfo info = server.getMBeanInfo(name);
System.out.println("JNDIclass Name:" + info.getClassName());
} catch (InstanceNotFoundException e3) {
// TODO Auto-generated catch block
e3.printStackTrace();
}


but this is giving me the below like error stack trace.
