EJBException in Servlet (EJB3 Trailblazer)
Hi I followed the EJB3 Tutorial on Authors and Articles and Deployed my application. Calling the Servlet under http://localhost:8080/authors/authors results in the following Exception.
Any idea? My guess is that I need to start the Hypersonic database and/or configure JBoss/EJB3 to work with a persistance layer but the trailblazer doesn't contain any information on that. But maybe its a completely different problem here
Greetings,
