Hi,
I have installed Tomcat 4.1.18 on windows 2000 sp3 and  Jdk1.4
after I download Cocoon 2.0.4 src and I follow instruction in Install file I have used the manual installation: 
  •  .\build.bat -Dinclude.webapp.libs=yes -Dinstall.war=%TOMCAT_HOME%\webapps webapp
  • copy .\build\cocoon\cocoon.war %TOMCAT_HOME%\webapps\cocoon.war

  •  Copy xerces-XXX.jar, xalan-XXX.jar, and the xml-apis.jar from the .\lib\core\ to the %TOMCAT_HOME%\common\endorsed directory

  • Restart the servlet engine
Cocoon seem work fine when I open http://localhost:8080/cocoon/ with internet esplorer, but when I go on Cocoon Portal login page( http://localhost:8080/cocoon/sunspotdemoportal ) and I try enter with  User: cocoon Password: cocoon  or User: guest Password: guest
I have  this answer:
