Answer 1

Hi,
if you are using this code for obtaining JNDI from a client (not on the server), you should indeed initialize JNDI environment like this:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "...");
Context context = new InitialContext(env);
See how to do it and more details here: http://download.oracle.com/docs/cd/A97688_16/generic.903/a97690/jndi.htm
Hope that helps,
