Error while trying to connect to weblogic from remote client

Question

Hi
I was trying to connect to JMX MBeanserver from a aremote client using some sample code that was posted. Ive tried even the samples that I found in the Admin Guide itself. Im not certain if any server configuration is needed. Ive tried the below with all three protocols t3, iiop, http with the same result. I had also enabled IIOP on the server through the console.
I get an error when trying to conenct using the JMXConnection Factory i.e. at the last line of the following code:
String protocol = "t3"; // can be t3, http, iiop
String hostname = "santapoco.eng";
int port = 7001;
String uri = "/jndi/"+"weblogic.management.mbeanservers.runtime";
JMXServiceURL serviceURL = new JMXServiceURL(protocol, hostname, port, uri);
Hashtable h = new Hashtable();
h.put(Context.SECURITY_PRINCIPAL, "weblogic");
h.put(Context.SECURITY_CREDENTIALS, "weblogic");
     h.put(JMXConnectorFactory.PROTOCOL_PROVIDER_PACKAGES, "weblogic.management.remote");
JMXConnector connector =JMXConnectorFactory.connect(serviceURL, h);
The error is:
"Root exception is java.rmi.ConnectIOException: error during JRMP connection establishment; nested exception is:
     java.io.EOFException]
     at weblogic.jrmp.Context.lookup(Context.java:189)"

This is what worked for me:
URI uri = new URI(args[0]);
JMXServiceURL serviceURL =
new JMXServiceURL(uri.getScheme(), uri.getHost(), uri.getPort(),
"/jndi/weblogic/management/mbeanservers/runtime");
Hashtable h = new Hashtable();
h.put(Context.SECURITY_PRINCIPAL, "system");
h.put(Context.SECURITY_CREDENTIALS, "ejb2come");
// String[] jmxCredentials = new String[]{ "system", "ejb2come" };
// h.put(JMXConnector.CREDENTIALS, jmxCredentials);
h.put(JMXConnectorFactory.PROTOCOL_PROVIDER_PACKAGES,
"weblogic.management.remote");
h.put(Context.PROVIDER_URL, args[0]);
// h.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
h.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
// InitialContext ic = new InitialContext(h);
// ic.lookup("weblogic/management");
JMXConnector connector = JMXConnectorFactory.connect(serviceURL, h);
MBeanServerConnection connection = connector.getMBeanServerConnection();
NOTE this was with weblogic 91--
