OK, I managed to create a trimmed down version of my application. There's still plenty of JAR's (the war is 11MB), but only 3 classes and just a few config files. http://rapidshare.com/files/62738527/myproject-1.0-SNAPSHOT.war.html Once you have deployed the war, you should be able to go to http://localhost:8080/myproject-1.0-SNAPSHOT/mainMenu.html or http://localhost:8080/mainMenu.html (depending on whether you are using tomcat or jboss) and see a list of users from app_user database table. app_user should have two fields, "id" and "username". This war assumes you have MySQL running on localhost, and have user "root" with password "erofog". Or you may change the username and password in jdbc.properties in WEB-INF/classes/ You should be able to see whether you get deploy-time classloading errors or not, even if you don't have a MySQL server at all. So mysql is not really necessary. If you don't have mysql you will still get some deployment time errors, but deployment should be successfull and you can access the page and get something like: javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: Cannot open connection I have tested on 1. tomcat 6.0.14 - works fine 2.
