Subject Mysterious Exception while server startup
Date Wed, 07 Jul 2004 13:33:00 GMT
Hello,
I run here a tomcat 5.0.27 server on windows 2000 with jsdk1.4.2-04.
The following happens rarely and it seems only to happen when I start Tomcat
in Eclipse 3 
(Sysdeo 3.0.0 alpha1 plugin).
After processing all contextes on startup I get sometimes the following 
Exception:

WARNUNG: Error registering contexts

INFO: Server startup in 30844 ms

When it happens all Contextes are not available and when I stop and restart
Tomcat with the plugin 
in Eclipse after this it ALWAYS happens until I restart Eclipse!.

Did somebody else encounter this problem?

Greetings,
Martin Gr√ľneberg
