JNDI lookup the EJB3 beans from Action class

[Jan Kozak]

Hi, I want to integrate EJB 3 with Struts 1.3, I use Grassfish V2 and Netbeans 6 IDE.

I have this code in EJB module:

Remote interface:

@Remote 
public interface KategorieFacadeRemote 
... 

implement this interface:

@Stateless(mappedName="KategorieFacade") 
public class KategorieFacade implements KategorieFacadeRemote 
... 

in web.xml there is this:

<ejb-ref>
        <ejb-ref-name>KategorieFacade</ejb-ref-name>
        <ejb-ref-type>Session</ejb-ref-type>
        <remote>sessions.KategorieFacadeRemote</remote>
    </ejb-ref>

In Action I have this method (generatel automatic from Netbeans using "Call Enterprise Bean"):

private KategorieFacadeRemote lookupKategorieFacade() {
        try {
            Context c = new InitialContext();
            return (KategorieFacadeRemote) c.lookup("java:comp/env/KategorieFacade");
        } catch (NamingException ne) {
            java.util.logging.Logger.getLogger(getClass().getName()).log(java.util.logging.Level.SEVERE, "exception caught", ne);
            throw new RuntimeException(ne);
        }
    }

whitch I use in execute method of Action like this:

public ActionForward execute(ActionMapping mapping, ActionForm  form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception 
    {
       KategorieFacadeRemote facade = lookupKategorieFacade();

But it gives me a exception:

java.rmi.RemoteException: ; nested exception is:
javax.naming.ConfigurationException: Invalid URL: localhost [Root exception is java.net.MalformedURLException: no protocol: localhost]

The stack trace makes it look like you are showing us the wrong method for the EJB lookup.
