  The Web User Interface Has Experienced an Error


The webUI has encountered an exception condition that it does not know 
how to handle.

Possible causes could be that the database is not responding, the 
OpenNMS application has stopped or is not running, or there is an issue 
with Tomcat.

You can try going to the main page and hitting "refresh" in your 
browser, but there is a good chance that will have no effect. Please 
bring this to the attention of the person responsible for maintaining 
OpenNMS for your organization, and have them insure that OpenNMS, Tomcat 
and the database are all running without errors.
