Re: Restart problem
Hi Charles, thank you for your tip. I solved now my problem. My application waited for a service wich was not initialized before the application. A classical deadlock which of course do not appear when I start Tomcat first (with the needed service) and then deploy my application ;-) kind regards Artur Osmanov 2010/10/20 Caldarale, Charles R chuck.caldar...@unisys.com From: Artur Osmanov [mailto:a.osma...@52north.org] Subject: Restart problem But if I stop Tomcat and start it again Tomcat hangs and nothing works anymore.

Restart problem
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.
