Subject Problem cocoon2 installation
Date Mon, 26 Mar 2001 08:36:02 GMT
Hi all,
now that I can use Cocoon 8.1.2 well, I have decided to pass to Cocoon 2 to find out the big
advantages I read every day in the Mail List.
I have tried to install Cocoon with these instructions:

* got C2 from CVS
* build C2 cocoon.war
* installed Tomcat 4.0-b1
* copied cocoon.war to Tomcat's webapps dir
* started tomcat

The problem is that when I try to conect to:
http://mylocalhost:8090/cocoon/
I receive this error:

A Servlet Exception Has Occurred
