I was doing some experiments with Hibernate and JBoss in Eclipse (no Maven at this stage), and I easily managed to realize a working standalone java project that reads/writes a mysql DB.
I wanted to set up a EAR archive including the same exact simple java project. This is what I have in mind:
-
EJBHibProjectEAR: the ear project;
-
EJBHibProjectEJB: the ejb project, it has just one EJB MySessionBean with an hello() method that should invoke the DB access logic;
-
EJBHibProjectHIB: the simple java project with entities and db access logic;
-
EJBHibProjectWEB: the web project. It has a servlet that calls a stateless EJB that should eventually use the
[...]HIB project methods to store an object.
The hibernate project alone is working. The ear project alone is working too: the servlet is able to invoke the ejb and show a test string (returned by the bean) to the browser.
But I'm not being able to make it work all together: when I add the HIB project to the EAR
and try to run the project, I get this error

Googling for a solution, the problem should be on how libraries are organized in the HIB project. This is the workspace:
My doubts are:
1 - Is this a correct/clean way to organize the project? Using a java project with DB access logic and including it as lib in an EAR and invoking it via EJB?
2 - Why do I get those errors? If it's a libraries problem, how should I reorganize them?
3 - In general, is it correct that Eclipse adds server runtime libraries to a simple Java project that "joins" the EAR project? Do I need those libraries in my case?
