I get a 404 error when trying to access http://servername/zenworks or https://servername/zenworks. The other webapps work: https://servername/zenworks-systemupdate/, etc. The zcc.log file only contains lines like this:

[DEBUG] [06/05/2014 10:59:51.594] [24845] [ZENServer] [11] [zenworks] [ZCC] [] [
ZENworks Initialized on (/opt/novell/zenworks/share/tomcat/webapps/zenworks/)] [
] [] [] [ZENServer]

The loader-messages.log seems to be mostly successful inventory and other messages.

Where else can I look for clues to what's wrong?
