Java EE Applications tutorial help desired

Rate this Message:
Hello, I'm trying to complete the Getting Started with Java EE Applications tutorial located here http://www.netbeans.org/kb/60/javaee/ejb30.html I'm using Netbeans 6.1 with everything default during setup Everything goes fine until I try to run it, and the glassfish server gives me this error about the ListNews servlet Class [ Lejb/NewsEntityFacadeLocal; ] not found. Error while loading [ class web.ListNews ] Error in annotation processing: java.lang.NoClassDefFoundError: Lejb/NewsEntityFacadeLocal; deployed with moduleid = NewsApp StandardWrapperValve[ListNews]: PWC1406: Servlet.service() for servlet ListNews threw exception java.lang.NoClassDefFoundError: ejb/NewsEntityFacadeLocal And this error with the PostMessage servlet StandardWrapperValve[PostMessage]: PWC1406: Servlet.service() for servlet PostMessage threw exception java.lang.NullPointerException I have been unable to determine on my own, or with google's help, what the problem is. It appears that the EJB binding isn't happening, but I'm clueless how to debug or fix. So I try this tutorial on a fresh install on a different computer, and I can't even get the servlet to call the bean This part of the instructions: When you click Finish, the class ListNews.java opens in the Source Editor. In the Source Editor, do the following: 1. Right-click in the source code and select Enterprise Resources > Call Enterprise Bean. 2. In the Call Enterprise Bean dialog box, select NewsEntityFacade and click OK. When you click OK, the entity bean resource is injected in the servlet using the @EJB annotation. When I select NewsEntityFacade, the UI says "Selected bean is not in the same module or enterprise application" This is another problem I'm confused about, both the war and ejb are in my enterprise application, so what could be the problem? Other problems: When clicking finish on the Create New Enterprise Application, it frequently stalls at 11% and "Creating new project" Cancelling and redoing the dialog is a work around Thanks for your help - Russ ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!

Hi Russ,
Your problem is a typo some where in your NewsEntityFacadeLocal. Refer to error "Lejb/NewsEntityFacadeLocal" versus expected "ejb/NewsEntityFacadeLocal". Note the "L" infornt of the ejb.

Regarding the issue with the class not found, make sure that you are
using the facade class in your bean, and not annotating directly to local. The tutorial creates a NewsEntityFacade that should implement the NewsEntityFacadeLocal, and the former is what you should have annotated. Regarding nb stalling. Did your Netbeans crash recently? I had a similar issue with NB some months ago after a crash. Check if there are any hanging processes that were not stopped when you restarted if that's the case. Also, check the NB logs for more info, and delete any unneeded .Netbeans cache files. ..\W Russ ² wrote: > Hello, I'm trying to complete the Getting Started with Java EE Applications tutorial located here http://www.netbeans.org/kb/60/javaee/ejb30.html > I'm using Netbeans 6.1 with everything default during setup > > Everything goes fine until I try to run it, and the glassfish server gives me this error about the ListNews servlet > > Class [ Lejb/NewsEntityFacadeLocal; ] not found.

Thank you for your help. I tried changing the import and @EJB from the NewsEntityFacadeLocal to NewsEntityFacade and it gives me the same error with a new class name. However it does now have a new line in the output regarding a binding name. I thought this was strange because its regarding the PostMessage servlet, in the middle of all these messages for my ListNews servlet. Class [ Lejb/NewsEntityFacade; ] not found. Error while loading [ class web.ListNews ] Error in annotation processing: java.lang.NoClassDefFoundError: Lejb/NewsEntityFacade; deployed with moduleid = NewsApp Binding name:`java:comp/env/web.PostMessage/queue` StandardWrapperValve[ListNews]: PWC1406: Servlet.service() for servlet ListNews threw exception java.lang.NoClassDefFoundError: ejb/NewsEntityFacade --- On Wed, 5/7/08, Wendy Bossons <wbossons@...> wrote: > From: Wendy Bossons <wbossons@...> > Subject: Re: [nbj2ee] Java EE Applications tutorial help desired > To: nbj2ee@... > Date: Wednesday, May 7, 2008, 1:11 PM > Regarding the issue with the class not found, make sure that > you are > using the facade class in your bean, and not annotating > directly to > local.
