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:
Exception StackTrace: java.lang.NullPointerException

When i execute the same code in 3.2.1, i get the following result:
10:49:25,484 [PoolThread-8] INFO [STDOUT] TEST: getServletContext()[EMAIL PROTECTED]
I've seen others on the web complaining about this problem. In all cases it seams to
be caused by overriding the init( ServletConfig config ) method in the servlet, but
not calling super.init(context). In my case i do override it, but DO call
super.init()...the config sent into the init method is NULL.
Does anyone have any ideas as to what is causing this? Or how to fix it?
thanks.
