Howdy,

Sorry 2 different Contexts, and my brain was all messed up.  When I'm
refering to my Context
Constructor it's actually the main servlet constructor (which in our

PolarisContext).  Which
extends HttpServlet.

OK, that makes a bit more sense.  Although a similar argument applies.
Even though a servlet is a normal class, and you can create a
constructor for it and do stuff in the constructor, you probably
shouldn't.  Instead, stick with overriding Servlet methods, in this case
init.  The container is required to make the servlet context parameters
available to your servlet's init() method.  It's not required to make
them available to your servlet's constructor.  So for portability and a
little bit less of a headache, you're better off not writing a servlet
constructor and moving the constructor code to the servlet's init()
method.

Ok that worked great. I don't get the exceptions anymore but for some reason it's not pulling the params from the web.xml. Any Ideas?

code:
try {
username = this.getInitParameter("oracleUser");
password = this.getInitParameter("oraclePass");
System.out.println("user: "+username+"\npass: "+password);
} catch(Exception e) { e.printStackTrace(); }

web.xml:
<?xml version="1.0" encoding="ISO-8859-1"?>
