Subject Restart problem
Date Tue, 19 Oct 2010 19:43:54 GMT
Hello Tomcat users,

I have a big problem with Tomcat after restart. I try to solve this problem
some days and can not find any solution for it:

When I start Tomcat and copy the *.war file of my application to the webapps
folder everything is fine. Tomcat deploys the application as normal.
Everything runs.
But if I stop Tomcat and start it again Tomcat hangs and nothing works
anymore.

It is a GWT application. I also use hibernate and postgresql as database.
I have really no idea where the problem is. None of my servlets starts, no
exceptions, nothing...
The only solution I have by now is to stop Tomcat and delete the application
folder and the *.war from the webapps folder. Start Tomcat and then copy the
*.war
again to the webapps folder. But it is not a solution for a production
system.
I hope someone can help me with my problem. Log file entry is below.

Tomcat version: Apache Tomcat/6.0.29 with default configuration
Windows 7 Professional 64bit
hibernate 3.5.2
postgresql 8.3

kind regards
Artur Osmanov
