I am trying to do a simple hello world application with hibernate annotations +mySQL in netbeans.
I can successfully get hibernate to work as a stand alone application. (also the junit test works) However when the application is deployed to tomcat I get the following error:
java.lang.ExceptionInInitializerError
When it attempts to create the session factory
sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
I have spent the last 2 days searching the internet trying to find a solution and although it seems to be a common problem I've failed to find one.
Any help would be appreciated or equally if someone could point me to a step by step guide to writing a hello world web application using annotations and mysql in netbeans and deploying it to tomcat that would be equally great.
