[JBoss-user] getServletContext() throwing a NullPointer?

[Peter Luttrell]

I'm trying to get my webapp that works perfectly with JBoss3.2.1 (with 
Jetty) to work with JBoss3.2.3 with Jetty 4.2.14.

When i execute the following line of code in the doPost method of a 
servlet, i get a NullPointerException:

   System.out.println( "TEST: getServletContext()=" + getServletContext());

Here's the stacktrace:

Does anyone have any ideas as to what is causing this? Or how to fix it?

thanks.
