As I said my application is distributed in two tiers web tier and app tier,
I configured jms in app tier. Now my servlet in web tier has to send message to queue in app tier.
In case of accessing an ejb I create Properties Object
          Properties objProperties = new Properties();
          objProperties.put(Context.INITIAL_CONTEXT_FACTORY,"com.evermind.server.rmi.RMIInitialContextFactory");
          objProperties.put(Context.PROVIDER_URL,"ormi://localhost:9127");               
          objProperties.put(Context.SECURITY_PRINCIPAL, "admin");
          objProperties.put(Context.SECURITY_CREDENTIALS, "admin");                    
          InitialContext ic = new InitialContext(objProperties);
where I specify all the parameters mentioned above and use the lookup method to create a home interface and then create remote interface.
In case of sending a message to jms queue what properties should I pass to InitialContext object?
