Subject Problem running the portal sample [null pointer exception]
Date Mon, 22 Jul 2002 12:26:18 GMT
Hello,

I'm using:
SuSE Linux 8.0
JDK 1.4.0_01
Tomcat 4.0.4

I had a fresh checkout from the cvs head, built cocoon and tried to run 
the portal sample but I got an error immediatly.
am I missing something?
I got this error :

The org.apache.cocoon.components.treeprocessor.sitemap.PipelineNode 
notifies that java.lang.NullPointerException

with extra info :
