Hi All,
I'm experiencing an issue running our Seam application; the issue deals with entityManager.createQuery wherein no results are returned.
Example:
result = (User)entityManager .createQuery( "select poc.user from PointOfContact poc " + "where poc.organization.id=:oid and poc.primary=true") .setParameter("oid", organization.getId()) .getSingleResult();
Under JBoss AS and Hibernate/JPA, this query would return no results but this would be handled gracefully.
Now, under WebLogic (but ignore this fact, really, because it could happen under GlassFish or other JEE AS), I get a NullPointerException, such as:
]] Root cause of ServletException. javax.ejb.EJBException: EJB Exception: : java.lang.NullPointerException at com.bah.englink.ejb.pm.SkillExperienceManager.lookupExperienceLevels(SkillExperienceManager.java:244)
If I catch the NPE, the application resumes normally. But why the difference? Since the returned value of this query is displayed using JSF EL, could that be the culprit?
Thanks.
