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
