JNDI InitialContext Error

Question

Hello Experts,
I have a little problem with my Java programm:
Test remote = null;
*               try {*
//                  Create a new intial context, which loads from jndi.properties file.
*               Context ctx = new InitialContext();*
*               System.out.println("Context:" + ctx);*
//                  Look up the home interface using the JNDI name.
//                  This JNDI lookup returns a reference to an EJBHome instance.
*               TestHome home = (TestHome) ctx.lookup("sap.com/TestWorldEar/TestBean");*
*               System.out.println("TestHome:" + home);*
//                  Create a session object.
*               remote = home.create();*
*               System.out.println("Remote:" + remote);*
//                  Invoke the remote EJB methods, test and debug.
*               System.out.println("Result:" + remote.getWert());*
*               }  catch  (Exception e) {*
*               System.out.println("Exception: " + e.getLocalizedMessage());*
I always get the following error and I don't know how to solve the problem.
Exception: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial
I hope anybody of you can help me solving this problem.
Additional information:
The Java program is running on a XI (Netweaver 7.0).
I want to get information from a deployed EJB. The Bean still works.
Thank you for your answers in advance!!!
Greetings, Alexander

Hi,
this Exception is thrown after this result: Context:javax.naming.InitialContext@cdfc9c and before the lookup.
The complete Stack Trace is:
