Setting up Enterprise Application

Question

So, I'm setting up my first Enterprise Application project and I got some issues with it, which I think is some kind of configuration that I don't know.

I have the following structure on my project:

• Application
• Application-ejb
• Application-war

The Application contains within the other two. in my ejb I have some model classes and a couple of persistence with some simple SQLite. In my war I have just index.jsp and two servlet classes. In these servlet classes I try to instantiate a object from the EJB. On compile it's fine, but when I try to run I get java.lang.ClassNotFoundException.

When I try to run the application the Glassfish server reports the following:

INFO:   visiting unvisited references
INFO:   visiting unvisited references
SEVERE:   Class [ Lbr/edu/horario/persistence/DisciplinaManager; ] not found. Error while loading [ class br.edu.horario.servlets.disciplinaServlet ]
