This is my code:
package test.main;
import org.jboss.jmx.adaptor.rmi.RMIAdaptor;
import java.util.*;
import javax.management.*;
import javax.naming.*;
public class TestMain {
public static void main(String args[]) throws Exception {
System.out.println("Starting");
Properties props=new Properties();
props.put(InitialContext.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
props.put(InitialContext.PROVIDER_URL, "jnp://localhost:1099");
props.put(InitialContext.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
InitialContext ic = new InitialContext(props);
Hashtable icHash = ic.getEnvironment();
Enumeration enumHash = icHash.keys();
System.out.println("Key num: " + icHash.size());
while(enumHash.hasMoreElements()) {
Object nextIc = enumHash.nextElement();
System.out.print("Keys: "+nextIc.toString());
System.out.println(" = "+icHash.get(nextIc));
}
System.out.println("Initial Context ok: ");
NamingEnumeration names = ic.list("");
System.out.println("Has More: " + names.hasMoreElements());
while(names.hasMoreElements()) {
System.out.println((String)
names.nextElement().toString());
}
RMIAdaptor server = (RMIAdaptor)
ic.lookup("jmx/invoker/RMIAdaptor");
System.out.println("RMIAdaptor ok: "+server.getMBeanCount());
System.out.println("Name: " + server.getDefaultDomain());
===> ObjectName nameTest = new ObjectName("jboss:service=JNDIView");
MBeanInfo info = server.getMBeanInfo(nameTest);
System.out.println("Name: " + info.getClassName());
System.out.println("Finished");
}
}
This is the error where arrow is:
