I'm having the same problem as the above poster. My system isn't a fresh install, I had fedora core 7 on the system (and the help system running fine), did an upgrade via yum to 8 and now I'm having this problem. I try to run help and I get: HTTP ERROR: 500 Class org.apache.jasper.servlet.JspServlet does not implement the requested interface javax.servlet.Servlet RequestURI=/help/index.jsp Powered by Jetty:// -- This is an email sent via The Fedora Community Portal https://fcp.surfsite.org https://fcp.surfsite.org/modules/newbb/viewtopic.php?post_id=218422&topic_id=47292&forum=10#forumpost218422 If you think, this is spam, please report this to webmaster@xxxxxxxxxxxxxxxx and/or blame mfterman@xxxxxxxxxx
