EJB-annotation does not work, why is that?

Hello,

My @EJB-annotation does not work, why is that?

I need help to understand why my bean is null at the breakpoint below.

I have tried some different usage of the @EJB but none seems to get the bean injected/initiated.

To get it initiated I need to do a manually "InitialContext.doLookup".

(My environmen is Java 8 and Weblogic 14)

I got a interface like this:

[/code]
    package com.mycompany.cruds.interfaces;

    import java.io.Serializable;
    import java.sql.SQLException;
    import java.util.List;

    import javax.naming.NamingException;

    import com.mycompany.cruds.domain.Domain;
    import com.mycompany.cruds.domain.DomainSearchCriteria;

    public interface CRUDS {
       
        public Serializable create(Domain domain) throws NamingException, SQLException;
       
    }
[/code]

...and an other interface like this:

[code]
    package com.mycompany.cruds.interfaces;

    import javax.ejb.Local;

    @Local
    public interface CrudSessionLocal extends CRUDS {
       
        public static final String JNDI_NAME = "java:global.cruds-app.server.CrudsSessionBean!com.mycompany.cruds.interfaces.CrudSessionLocal";

    }
[/code]

...these are packed in a interfaces.jar

I got a stateless bean like this:

[code]
    package com.mycompany.cruds.server;

    import java.io.Serializable;
    import java.sql.SQLException;
    import java.util.List;

    import javax.ejb.Stateless;
    import javax.naming.NamingException;

    import com.mycompany.cruds.domain.Domain;
    import com.mycompany.cruds.domain.DomainSearchCriteria;
    import com.mycompany.cruds.interfaces.CrudSessionLocal;
    import com.mycompany.cruds.server.dao.DomainDaoBean;

    @Stateless
    public class CrudsSessionBean implements CrudSessionLocal {

        private DomainDaoBean domainDaoBean = new DomainDaoBean();
       
        public CrudsSessionBean() {
            super();
        }
       
        @Override
        public Serializable create(Domain domain) throws NamingException, SQLException {
           
            Serializable serializable = domainDaoBean.create(domain);
            return serializable;
        }

    }
[/code]

...that is packed in a server.jar

I got a servlet like this:

[code]
    package com.mycompany.cruds.web_client;

    import java.io.IOException;
    import java.sql.SQLException;

    import javax.ejb.EJB;
    import javax.naming.InitialContext;
    import javax.naming.NamingException;
    import javax.servlet.ServletException;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;

    import com.mycompany.cruds.domain.LogItem;
    import com.mycompany.cruds.domain.LogItem.Level;
    import com.mycompany.cruds.interfaces.CrudSessionLocal;

    public class CreateServlet extends HttpServlet {

        private static final long serialVersionUID = 1L;

        //@EJB   
        //@EJB(beanName = "CrudsSessionBean")
        @EJB(lookup = "java:global.cruds-app.server.CrudsSessionBean!com.mycompany.cruds.interfaces.CrudSessionLocal")
        private CrudSessionLocal crudSessionLocal;
       
        public CreateServlet() {
            super();
        }

        protected void doPost(HttpServletRequest request, HttpServletResponse response)
                throws ServletException, IOException {


        //BREAKPOINT
            if (crudSessionLocal == null) {
                try {

                    crudSessionLocal = (CrudSessionLocal) InitialContext.doLookup(CrudSessionLocal.JNDI_NAME);

                } catch (NamingException e) {

                }
            }

            ...
[/code]
...that is packed in a web-client.war

All three artifacts are packed in a ear with a application.xml:
[code]
      <display-name>app</display-name>
      <module>
        <ejb>server.jar</ejb>
      </module>
      <module>
        <web>
          <web-uri>web-client.war</web-uri>
          <context-root>/web-client</context-root>
        </web>
      </module>
      <library-directory>lib</library-directory>
    </application>
[/code]

...inside lib/ is the interfaces.jar of course.
Do you guys see why the @EJB-annotation does not work?
