I got a Jndi lookup timed out exception when I tried to look up a WebLogic service through a very simple Java program with jboss jar and jndi properties. Can anyone please help me find out what is wrong and what is the right provider url I should use?

My code is like:
Properties jndiProps = new Properties();
jndiProps.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
jndiProps.setProperty("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
jndiProps.setProperty("java.naming.provider.url","http://njfialxdev007:9193");

InitialContext jndiContext = new InitialContext(jndiProps);
System.out.println("got intial context");
Object ref = jndiContext.lookup("Environment");

The exception I got is :
javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out]
at org.jnp.interfaces.NamingContext.discoverServer(NamingContext.java:1034)
at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1103)
at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:470)
at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:463)
at javax.naming.InitialContext.lookup(InitialContext.java:347)
at EJBClient.main(EJBClient.java:110)

I also tried to set jndi properties in JVM parameters, and used jnp://dev007:9193. But I always got the same exception on lookup call. The jboss I use is version 3.0.5.

However I am able to use a similar java program with weblogic context factory and provider.url=t3://dev007:9193 to lookup and get the home interface object.

Thanks a lot.
