Hey guys,
so I'm trying to do a JNDI lookup on a simple EJB. I'm following these
instructions: http://www.netbeans.org/kb/50/jboss-getting-started.html
Inside my listNews servlet I do the following:
private NewsEntityFacadeLocal lookupNewsEntityFacade()
{
try
{
Context c = new InitialContext();
return (NewsEntityFacadeLocal)
c.lookup("NewsApp/NewsEntityFacade/local");
}
catch(NamingException ne) {
Logger.getLogger(getClass().getName()).log(Level.SEVERE,"exception
caught" ,ne);
throw new RuntimeException(ne);
}
}
protected void processRequest(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try
{
Context c = new InitialContext();
//NewsEntityFacade ref =
(NewsEntityFacade)c.lookup("NewsApp/NewsEntityFacade/local");
NewsEntityFacade ref = (NewsEntityFacade)lookupNewsEntityFacade();
out.print("<h1>WE'RE GOOD!!!!!</h1>");
}
catch(Exception e)
{
e.printStackTrace();
}
Here is my NewsEntityFacade:
@Stateless
public class NewsEntityFacade implements NewsEntityFacadeLocal {
@PersistenceContext
private EntityManager em;
/** Creates a new instance of NewsEntityFacade */
public NewsEntityFacade() {
}
public void create(NewsEntity newsEntity) {
em.persist(newsEntity);
}
public void edit(NewsEntity newsEntity) {
em.merge(newsEntity);
}
public void destroy(NewsEntity newsEntity) {
em.merge(newsEntity);
em.remove(newsEntity);
}
public NewsEntity find(Object pk) {
return (NewsEntity) em.find(NewsEntity.class, pk);
}
public List findAll() {
return em.createQuery("select object(o) from NewsEntity as
o").getResultList();
}
}
and here is my NewsEntityFacadeLocal interface:
@Local
public interface NewsEntityFacadeLocal {
void create(NewsEntity newsEntity);
void edit(NewsEntity newsEntity);
void destroy(NewsEntity newsEntity);
NewsEntity find(Object pk);
List findAll();
}
When I run the code I get:

Any clues?
