[jboss-user] [JNDI/Naming/Network] - javax.naming.CommunicationException

[adoorsarath]

sir, 

I got the javax.naming.CommunicationException when I 

started writing my first JMS program. 

The code snippet is given below 

Properties properties = new Properties(); 
properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); 
properties.put(Context.PROVIDER_URL, "jnp://192.168.17.101:1099"); 
InitialContext jndiContext = new InitialContext(properties); 
TopicConnectionFactory conFactory = 
(TopicConnectionFactory)jndiContext.lookup("TopicConnectionFactory"); 

Error is there in JNDI lookup operation . If the client is there on the same machine it works fine.But if the client is Remote,it is showing the following error message


Error Message
