Neither I. We are using Windows server solution. But that should be same in NW.
If you go in NWA to Troubleshooting >> Logs and Traces >> Log Viewer.
or in the file system could be around here:
\usr\sap\AM0\J00\j2ee\cluster\server0\log\defaulttrace.trc or any other *.trc files. But better to work with NWA in browser, it's much more well-arranged. There have to be some error point You to the root cause.
Are you able to reach the page from the server where it is running? from localhost?
http://<localhost>:<port>/XMII/Menu.jsp
if yes, try to comment(by #) all lines in icm_filter_rules.txt and restart NW- Do not know the path from my head.
Sorry, can't help more. Just blind suggestions.
