Enterprise application setup

Question

So, I am setting up my first Enterprise Application project, and I have some problems with it, and I think this is some kind of configuration that I do not know about.

I have the following structure in my project:

• Application
• Application-EJB
• Application of war

The application contains two others. in my ejb I have some model classes and some persistence with some simple SQLite. In my warfare, I only have index.jsp and two classes of servlets. In these servlet classes, I'm trying to instantiate an object from EJB. When compiling, this is fine, but when I try to run, I get java.lang.ClassNotFoundException .

When I try to start 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 ] INFO: visiting unvisited references INFO: Loading application [horarioApplication#horarioApplication-war.war] at [horarioApplication-war] INFO: horarioApplication foi implantado com sucesso em 322 milissegundos.
