Is there some particular approach to ensure that an EJB module gets deployed to a web app correctly in Netbeans?
I'm coming at the EJB cookbook example, to invoke the Session Bean from the servlet. I cleared the glassfish output in Netbeans, did a clean-compile and run:
INFO: visiting unvisited references
INFO: visiting unvisited references
SEVERE: Class [ Lpakt/Salutation; ] not found. Error while loading [ class pakt.SalutationServlet ]
INFO: visiting unvisited references
INFO: Loading application [SalutationApplication-war] at [/SalutationApplication-war]
INFO: SalutationApplication-war was successfully deployed in 382 milliseconds.
INFO: processRequest..
WARNING: StandardWrapperValve[SalutationServlet]: Servlet.service() for servlet SalutationServlet threw exception
java.lang.NoClassDefFoundError: pakt/Salutation
at pakt.SalutationServlet.processRequest(SalutationServlet.java:30)
at pakt.SalutationServlet.doGet(SalutationServlet.java:45)
Why isn't the servlet loading pakt.Salutation?
the clean structure (uncompiled):

this is how the application builds.
