Hi,
to tell it from the beginning, I'm much of a newbie.

My Problem is that I have to move a running application from one Server to an other.
The source server is a win2003 with postgresql 8.2 and tomcat6 hibernet3.
The New Server is a win2012 with postgresql 9.2 and tomcat 6.

I droped and imported Database, created user, added pg_hba.conf. Then I installed Tomcat, then copied webapps files from the old server, checked hibernate.cfg.xml in /webapps/webap/ and /webapps/webap/WEB-INF/classes/ .
I replaced the old jdbc driver in \Tomcat 6.0\lib\ with the one for postgresql 9.2.

When I try running the application I recieve:
type Exception report
message Cannot open connection
description The server encountered an internal error that prevented it from fulfilling this request.
exception
