Tomcat 6 Admin Webapp Headache
Hi there,
I've just installed Tomcat 6 and am now trying to install the Admin webapp. Firstly, I couldn't find it anywhere on the tomcat website and I eventually (after loads of searching around on google) found the following:
http://www.apache.org/dist/tomcat/tomcat-5/v5.5.23/bin/apache-tomcat-5.5.23-admin.zip
Obviously this is the admin app for version 5, but I can't find anything for version 6.
I then unzipped it, and copied the webapps/admin directory to the Tomcat webapps directory. The webapp appears in the manager as started, but going to http://localhost/admin produced a blank page with the following error in the log:
WARNING: Unexpected error forwarding to login page

HtmlTag definitely exists in webapps/admin/WEB-INF/lib/struts.jar
Has anyone got any idea what's going on, and/or does anyone know how to get this working?
Thanks,
Chris.
