I have a stand alone Java Application running on WSAD 5.1. How do i get the initialcontext???

I am using the code

Hashtable props = new Hashtable ();
props.put (Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
props.put(Context.PROVIDER_URL,"iiop://localhost:2809");
Context ctx = new InitialContext(props);



It gives the following error.

javax.naming.NoInitialContextException: Cannot instantiate class: com.ibm.websphere.naming.WsnInitialContextFactory. Root exception is java.lang.ClassNotFoundException: com.ibm.websphere.naming.WsnInitialContextFactory

Please help.

Where is this java application file located? Try placing the file in EJB project and J2EE project. If the file is in Java client project - it wouldn't find the EJB context.

There could be some other ways to create the EJBContext - if you want to test it real quick, the above ways should work

Well thats a pretty obvious exception, you don't have the naming.jar in your classpath, you probably will need other dependencies as well from the websphere app\lib directory.

Vishi / Andre,

Thanks!
It works fine the way you suggested. How come? Also I need to run it as a standalone application, JUnit, what do i need to do. Add naming.jar, and what else.
