EJB dependency injection returns null in application container client

[usydrajani]

Hi

I want to do some performance testing for my algorithm. I need to run the  the client from inside the container so that the time I get should be actually for the read and update rather than invoking a remote command to server.

I am trying this example http://glassfish.java.net/javaee5/ejb/examples/Sless.html  with JBOSS 6.0 and Eclipse Indigo SR2.

So far the ejb is being deployed on server successfully, also the Client  ENC container is starting STARTED CLIENT ENC CONTAINER: NewAppClient

When I am runing client application from eclipse it is returning null for dependency injection. 

Exception in thread "main" java.lang.NullPointerException

          at Main.main(Main.java:11)

Here is code for the client

import ejb30.Sless;
import ejb30.SlessBean;
public class Main {
          // @EJB(name="NewApp/SlessBean/remote-ejb30.Sless")
             @EJB
             public static Sless sless;
          public static void main(String[] args) {
                     System.out.println(sless.toString());
                //  System.out.println("Sless bean says : " + sless.hello());
          }
          /* (non-Java-doc)
           * @see java.lang.Object#Object()
           */
          public Main() {
                    super();
          }
}

I have gone through this wiki tut https://community.jboss.org/wiki/HowToUseAnApplicationClientInJBoss-5to too but still unable to figure it out, how will it work.

I have attached server log and the jar files too.

I am not much familiar working from command line so it will be great if some one help me getting this done through eclipse IDE.

Thanks

You have to create an InitialContext and lookup the remote proxy. You can find examples within the docs depend to the JBoss version you use.

@EJB injection is only availabe uner container control.

Would not creating initial context make it as a remote lookup in JNDI, while What I want to is to connect  as a local client from within the container. As  given in the example http://glassfish.java.net/javaee5/ejb/examples/Sless.html

under the heading of "Application Client"  and "Standalone Java Client"

If you read the documentation in case of 'Application Client' the container is responsible to resolve the @EJB.

AFAIK if you use a remote standalone application outside of the server JVM this is not supported by JBoss. You have to use the 'Standalone Java Client' approach.

Ofcourse I read the documentation and  ACC should resolve the @EJB  dependency but I am getting error that is what my question is.

What you mean by ACC?

I only see a Main class and I suppose it is a simple client starting in a different (from server) JVM. In that case the @EJB is not resolved.

Also your link 'HowToUseAnApplicationClientI....' is not valid.

I followed this  https://community.jboss.org/wiki/HowtouseanapplicationclientinJBoss-5   and this   http://www.cs.hs-rm.de/~knauf/KomponentenArchitekturen2008/stateless/index.html  and it worked. I was missing some jar files when in class pah from command line.
