We have an application with backend JBoss, Hibernate and Front End Flex.

I am trying to define my first junit test for the backend.
I get a nullPointerException when calling the PersistenceContext.

The test is found and run by maven test.

The hibernate.cfg.xml is under Disposer\disposer-backend\disposer-ejb\src\main\resources

Error:-------------------------------------------------------------------------------
Test set: de.camsystems.disposer.testServices.ProjectServiceTest

at de.camsystems.disposer.dao.beans.ProjectDAOBean.getAll(ProjectDAOBean.java:62)
at de.camsystems.disposer.testServices.ProjectServiceTest.testFindAll(ProjectServiceTest.java:32)


Test Code:
public class ProjectServiceTest extends TestCase {


private ProjectDAO projectDAO = new ProjectDAOBean();

/**
* Tests
*/
public void testFindAll () throws Exception {
HashSet aHashSet = new HashSet();
List<Project> projects = this.projectDAO.getAll(aHashSet);
assertNotNull(projects);
assertTrue("There should be 122 projects, found: " + projects.size(),
projects.size() == 122);
}

}

ProjectDAOBean:
/**
* Session Bean for handling Projects
*
* @author Nebojsa Milic
*
*/
@Stateless
public class ProjectDAOBean implements ProjectDAO {

private static final long serialVersionUID = 3826891945688056002L;


@PersistenceContext(unitName="Disposer")
private EntityManager entityManager;

/**
* @return list of Project objects
*
* @ejb.interface-method
*/
@SuppressWarnings("unchecked")
public List<Project> getAll (Set<SearchObject> queryArray) {

List<Project> result = null;
Session session = (Session) entityManager.getDelegate();
Criteria criteria = session.createCriteria(Project.class);
criteria = SearchEngine.generateCriteria(queryArray, criteria);
criteria.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);
result = (List<Project>) criteria.addOrder(Order.asc("id")).list();
return result;
}
