Subject c2b2 install problem / c2b1 running fine ...
Date Tue, 18 Sep 2001 23:07:13 GMT
DearCocooners!

Can someone please help me? I get an internal server error after building Cocoon2 beta 2 and
placing it in tomcathome/webapps and so on. Cocoon 2 beta 1 is running fine.

Servlet engine is tomcat 3.2.1 on Windows98. At the bottom of this mail I included excerpts
from browser-windoe and cocoon.log.

Please show me the right way, much thanks in advance, Arno
