Hi there,
I have a problem with initialising a google web toolkit (gwt) application using hibernate under tomcat.
When using the same application from eclipse, everything works fine.
The setup looks as follows:
I placed all needed jars under WEB-INF/lib.
The gwt server files are placed under WEB-INF/classes. The db persistency with hibernate is used in an external project that I pack in a separate jar file, also placed in WEB-INF/lib. The hibernate configuration file is placed under WEB-INF/classes, as described in various sources.
When doing a server call that uses the hibernate functionality I get the following error:
03.10.2010 17:07:20 org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Allocate exception for servlet login

at java.lang.Thread.run(Thread.java:636)
The exception happens on line
Code:
Configuration configuration = new Configuration().configure();
in:
Quote:
public class MyHibernateUtil {
private static SessionFactory sessionFactory;
public static SessionFactory getSessionFactory() {
if (sessionFactory == null) {
try {
Configuration configuration = new Configuration().configure();
sessionFactory = configuration.buildSessionFactory();
} catch (Throwable ex) {
ex.printStackTrace();
throw new ExceptionInInitializerError(ex);
}
}
return sessionFactory;
}
}
Every help is appreciated.
Thanks,
Pascal
