Wildfly 8.2.1에서 EJB 2.1에 액세스할 때 ClassCastException이 발생하는 이유는 무엇입니까? (Why I am getting ClassCastException when accessing EJB 2.1 in Wildfly 8.2.1?)

P001_EJB에서 XDoclet 상태 비저장 세션 빈(EJB 2.1).

이것은 원격 인터페이스입니다:

package com.p001.ejb;

/**
 * Remote interface for Test1SLB.
 * @generated 
 * @wtp generated
 */
public interface Test1SLB extends javax.ejb.EJBObject
{
   /**
    * <!‑‑ begin‑xdoclet‑definition ‑‑>
    * @generated //TODO: Must provide implementation for bean method stub    */
   public java.lang.String foo( java.lang.String param )
      throws java.rmi.RemoteException;    
}

이것은 홈 인터페이스입니다:

package com.p001.ejb;

/**
 * Home interface for Test1SLB.
 * @generated 
 * @wtp generated
 */
public interface Test1SLBHome extends javax.ejb.EJBHome
{
   public static final String COMP_NAME="java:comp/env/ejb/Test1SLB";
   public static final String JNDI_NAME="Test1SLB";

   public com.p001.ejb.Test1SLB create()
      throws javax.ejb.CreateException,java.rmi.RemoteException;
}

P001_WAR P001Listener라는 Listener 클래스를 만들었습니다. contextInitialized 메소드에서 Test1SLB EJB의 foo 메소드를 호출하려고 합니다. 코드는 다음과 같습니다.

public class P001Listener implements ServletContextListener {

    public P001Listener() {
    }

    public void contextInitialized(ServletContextEvent sce)  { 
         System.out.println("P001Listener.java: contextInitialized(ServletContextEvent sce): inside");
         String test1SLBJNDIName = null;
         Class test1SLBHomeClass = null;
         InitialContext initialContext = null;
         Object namedObject = null;
         Object ejbHomeObject = null;
         Test1SLBHome test1SLBHome = null;
         Test1SLB test1SLB = null;
         String rtnValue = null;


         try {

            test1SLBJNDIName = "java:global/P001_EAR/P001_EJB/Test1SLB!com.p001.ejb.Test1SLB";
            System.out.println("P001Listener.java: contextInitialized(ServletContextEvent sce): test1SLBJNDIName=" + test1SLBJNDIName);

            test1SLBHomeClass = Test1SLBHome.class;
            System.out.println("P001Listener.java: contextInitialized(ServletContextEvent sce): test1SLBHomeClass=" + test1SLBHomeClass);

            initialContext = new InitialContext();
            System.out.println("P001Listener.java: contextInitialized(ServletContextEvent sce): initialContext=" + initialContext);

            namedObject = initialContext.lookup(test1SLBJNDIName);
            System.out.println("P001Listener.java: contextInitialized(ServletContextEvent sce): namedObject=" + namedObject);

            ejbHomeObject = PortableRemoteObject.narrow(namedObject, test1SLBHomeClass);
            System.out.println("P001Listener.java: contextInitialized(ServletContextEvent sce): ejbHomeObject=" + ejbHomeObject);

            test1SLBHome = (Test1SLBHome) ejbHomeObject;
            System.out.println("P001Listener.java: contextInitialized(ServletContextEvent sce): test1SLBHome=" + test1SLBHome);

            test1SLB = test1SLBHome.create();
            System.out.println("P001Listener.java: contextInitialized(ServletContextEvent sce): test1SLB=" + test1SLB);

            rtnValue = test1SLB.foo("pagal");
            System.out.println("P001Listener.java: contextInitialized(ServletContextEvent sce): rtnValue=" + rtnValue);

        } catch (NamingException ne) {
            ne.printStackTrace();

        } catch (ClassCastException cce) {
            cce.printStackTrace();

        } catch (RemoteException re) {
            re.printStackTrace();

        } catch (CreateException ce) {
            ce.printStackTrace();

        }
    }

    public void contextDestroyed(ServletContextEvent sce)  { 
        System.out.println("P001Listener.java: contextDestroyed(ServletContextEvent sce): inside");
    }

}
