I didn't explain it in my book because I was trying not to write a
Weblogic-specific book. There were a few areas where I couldn't avoid it,
of course, but I put a lot of effort into writing code that would work in
_any_ server (even ones that have yet to be written).
I'm guessing that the trouble you're having is because the InitialContext
needs to be fiddled with in order to work against a remote machine. Here's
a method from one of the Weblogic sample classes that should do the trick.
static public Context getInitialContext() throws Exception {
Hashtable h = new Hashtable(); h.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory"); h.put(Context.PROVIDER_URL,
url); if (user != null) { System.out.println ("user: " + user);
h.put(Context.SECURITY_PRINCIPAL, user); if (password == null)
password = ""; h.put(Context.SECURITY_CREDENTIALS, password); }
return new InitialContext(h); }
You'll probably also be missing some stub classes. The easiest way to make
sure you've got everything you need is to use automated tools.
Here's a document on how to prepare a client-side .zip file for
distribution with applications.

and here's one for applets
