Subject Null Pointer Exception in initial How to setup
Date Mon, 16 Sep 2002 14:23:53 GMT
 I've tried a couple times to work the example on
 http://jakarta.apache.org/cactus/howto_tomcat.html 
I am using following versions
   tomcat 4.0.4 
   Cactus 3.8.1
   JDK     1.4.0_02

Can someone help me...

 Here is a sample of my stack trace:
