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.
