Hi all , i am using linux6.1 , Tomcat3.2.1 and jBoss2.1. Properties props = new Properties(); props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); props.put(Context.PROVIDER_URL, "localhost:1099"); If i have installed jboss container in my server name ="point6" and deploy ejb bean on it and without any error message. So my question is do i need to change the properties value and name ?? Do i need to changed the Context.PROVIDER_URL ?? And how to integrate tomcat and jboss. I follow the on-line documentation for "how to" , it always give me the "NoClassDefFound" error ? Anyone please explain it to me . Thanks wt. -- -------------------------------------------------------------- To subscribe: [EMAIL PROTECTED] To unsubscribe: [EMAIL PROTECTED]
