initialize the connection as follows:

    public static void InlCctn(String Adr, String AdrUsr, String AdrPswd) throws IOException, MalformedURLException {
        JMXServiceURL SvcUrl =
            new JMXServiceURL("service:jmx:iiop://" + Adr + "/jndi/weblogic.management.mbeanservers.domainruntime");
        Hashtable h = new Hashtable();
        h.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
        h.put(Context.SECURITY_PRINCIPAL, AdrUsr);
        h.put(Context.SECURITY_CREDENTIALS, AdrPswd);
        //        String[] credentials = new String[] { AdrUsr, AdrPswd };
        //        h.put("jmx.remote.credentials", credentials);
        cctor = JMXConnectorFactory.connect(SvcUrl, h);
        mbsc = cctor.getMBeanServerConnection();
    }

uses both ways to connect with the same error.

look forward to

is it the problem of Weblogic configuration or my method?
