JMX Connector

[garlam]

I developed a simple Java client in order to retrieve several information from WebSphere AS using JMX. Thi exception is raised:

"Could not create SOAP Connector to connect to host localhost at port 8880"

This is the code:

/*
 * XWasClient.java
 */

package com.xech.ws.client;

// Librerie WebSphere 
import com.ibm.websphere.management.AdminClient;
import com.ibm.websphere.management.AdminClientFactory;

import com.ibm.websphere.management.exception.ConnectorException;  

// Librerie java
import javax.management.ObjectName;
import javax.management.MalformedObjectNameException;

import java.util.Properties;
import java.util.Set;

/**
 * Client per WebSphere Application Server. Recupera i dati
 * tramite JMX.
 */
public class XWasClient {
	
	protected final int NUM_PARAMS 	= 4;
	
	protected final String USAGE		=	"USAGE: " + XWasClient.class.getName() + " <host> <port> <user> <password>";
	
	protected String host;
	protected String port;
	protected String user;
	protected String password;
	
	///////////
	
	/**
	 * Metodo main.
	 *
	 * @param args Argomenti passati da linea di comando
	 */
	public static void main(String args[]) {
		new XWasClient(args);
	}
	
	/////////////
	
	/**
	 * Costruttore
	 *
	 * @param args Argomenti passati da linea di comando
	 */
	public XWasClient(String args[]) {
		
		if (args.length < NUM_PARAMS) {
			System.out.println(USAGE);
			System.exit(0);
		}
		
		// parsing parametri
		host 			= args[0];
		port 			= args[1];
		user 			= args[2];
		password 	= args[3];
		
		System.out.println("HOST:     " + host);
		System.out.println("PORT:     " + port);
		System.out.println("USER:     " + user);
		System.out.println("PASSWORD: " + password);
		
		try {
			connect();
		}
		catch (ConnectorException e) {
			System.out.println("Exception creating admin client: " + e);
		}
		catch (Exception e) {
			System.out.println("Exception while contacting WAS server: " + e);
		}
	}
	
	/**
	 * Effettua la connessione all'application server
	 */
	protected void connect() throws ConnectorException, MalformedObjectNameException {
		
		// Costruisco il client
		
		Properties connectProps = new Properties();
		
		connectProps.setProperty(AdminClient.CONNECTOR_TYPE, AdminClient.CONNECTOR_TYPE_SOAP);

		connectProps.setProperty(AdminClient.CONNECTOR_HOST, 	host);
		connectProps.setProperty(AdminClient.CONNECTOR_PORT, 	port);
		connectProps.setProperty(AdminClient.USERNAME, 				user);
		connectProps.setProperty(AdminClient.PASSWORD, 				password);

		AdminClient adminClient = AdminClientFactory.createAdminClient(connectProps);
		
		// Recupero i parametri
		
		String query = "WebSphere:*,type=JVM,j2eeType=JVM";
		ObjectName queryName = new ObjectName(query);
		ObjectName jvm = null;
		Set s = adminClient.queryNames(queryName, null);
		if (!s.isEmpty())
    	jvm = (ObjectName)s.iterator().next();
		else
    	System.out.println("jvm MBean was not found");
		
		
	}
}

Using the wsadmin client all works fine. Any suggestions ?

Thanks in advance,
Mauro.
