David,
config.properties is used only by the client.jpr. Not by the Web.jpr
config.properties file has been provided for looking up resources[EJB, Datasources] from JNDI tree of OC4J.
Since servlet and other resources are in the same container[Single JVM] there is no need to specify the username, password, Provdier_URL at the time of lookup.
Look at the init method of EJBHotelServlet.java :
Context ctx = new InitialContext();
// Acquire the home interface handle and call the create
//method on it
homeInterface = (HotelSystemHome)ctx.lookup("OneEJBHotel");
Here servlet looks up EJB without any authentication information, as servlet and EJB are in the same container.
Whereas Stand alone client is running outside the OC4J.
So the stand alone client need to authentcate itself for looking up the resources from JNDI tree.
Look at the getHotelSystemBean method of EJBHotelSample.java :
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, prop.getProperty("Initial_Context_Factory"));
env.put(Context.SECURITY_PRINCIPAL, prop.getProperty("Principal"));
env.put(Context.SECURITY_CREDENTIALS, prop.getProperty("Credential"));
env.put(Context.PROVIDER_URL, prop.getProperty("Provider_Url") );
// Associate the properties with the context
Context ctx = new InitialContext(env);
// Acquire the home interface handle and call the create
//method on it
homeInterface = (HotelSystemHome)ctx.lookup("OneEJBHotel");
Here stand alone client looks up EJB by specifying the authentication information, as stand alone client and EJB are running in different JVM's.
Hope this helps...
Cheers
