JMS1.1 Domain Unification sample using OC4J 10g

Question

I am trying to run the JMS1.1 Domain Unification sample using OC4J 10g
I am not sure why I get the Invalid provider URL exception at run time when trying to run AsyncClient using listenTopic in Ant. The code prints out the provider URL accurately from my ConnectionParam.java file but exception happens after that. I am running the J2EE container using OC4J and can access http://localhost:8888/adminoc4j as an admin user.

C:\JMS1.1>c:\apache-ant-1.6.1\bin\ant listenTopic
Buildfile: build.xml
listenTopic:
[java] local url...
[java] http://localhost:8888/adminoc4j
[java] env Hashtable populated...
[java] javax.naming.NamingException: Invalid provider URL
[java] at com.evermind.server.rmi.RMILocation.parseURL(RMILocation.java
:83)

This is the initialize method from AsyncClient.java.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++=
public void initialize() throws Exception{
Hashtable env = new Hashtable();
// set the environment properties
env.put(Context.INITIAL_CONTEXT_FACTORY,
     "com.evermind.server.rmi.RMIInitialContextFactory");
System.out.println("local url...");
System.out.println(ConnectionParams.PROVIDER_URL);
env.put(Context.PROVIDER_URL, ConnectionParams.PROVIDER_URL);
env.put(Context.SECURITY_PRINCIPAL, ConnectionParams.USERNAME);
env.put(Context.SECURITY_CREDENTIALS, ConnectionParams.PASSWORD);
     System.out.println("env Hashtable populated...");
// get the initial context
InitialContext ctx = new InitialContext(env);
     System.out.println("got context...");
// lookup the queue and topic objects
Destination topic = (Destination) ctx.lookup("jms/sampleTopic");
     System.out.println("looked up topic...");
// lookup a connection factory
ConnectionFactory factory = (ConnectionFactory) ctx.lookup("jms/sampleConnectionFactory");
// create a connection
Connection connection = factory.createConnection();

Sorted out the answer myself.

The URL in ConnectionParams should use ormi protocol as given in the sample example.
Good example and it all works! Thanks.

public class ConnectionParams{
// variable for OC4J Provider URL
public static String PROVIDER_URL="ormi://localhost:23791";
