[plug] Re: Java servlets with tomcat application server

[David Buddrige]

Hi all, 

I just thought I'd let u all know, the problem that I was experiencing was 
because I didn't have the line: 

<?xml version="1.0" encoding="ISO-8859-1"?>
       <!DOCTYPE web-app
           PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
           "http://java.sun.com/dtd/web-app_2_3.dtd"> 

At the beginning of my web.xml file.  I added this, and it all seems to work 
fine now. 

thanks heaps for everyone's help. 

David.
