Accessing Environment entries in WebSphere 3.5 Adv.

[Horaci Macias]

Does anybody know how to access Environment entries of an EJB in WebSphere ? I've tried the following:

Properties props = new Properties();
props.put(javax.naming.Context.PROVIDER_URL, "iiop:///");
props.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY, "com.ibm.ejs.ns.jndi.CNInitialContextFactory");
javax.naming.InitialContext ctx = new javax.naming.InitialContext(props);
javax.naming.Context env = (javax.naming.Context) ctx.lookup("testing");

the Environment entry I want to read is called "testing", and I've tried lookup("java:comp/env/testing"), lookup("java:comp"), and many other combinations with no luck. If anyone could paste a sample code....
Thank you in advance,
