    Stateless Beans in ejb jar  working in Jboss 7.1  but not in Jboss  5.1

    jcmeena

      I have created an EJB project which has the following java files .

      It does not deploy on the JBoss 5.1.0 and spits out deployment error  which is appended after java code below . But the same jar gets deployed on JBoss AS 7.1.

      Why the jar is not getting deployed on JBoss 5.1 ?

      Please note that , The bean implementation BeanA has-a  BeanB's local interface .And bean implementation of BeanB has-a BeanA's local interface so it is  a cycle.

       

       

      BeanALocalInterface.java

       

      package com.xyz;
      import javax.ejb.Local;
      @Local
      public interface BeanALocalInterface {
        public void executeLocal();
      }
      
      

       

      BeanA.java

       

      package com.xyz;
      import javax.ejb.EJB;
      import javax.ejb.Stateless;
      @Stateless
      public class BeanA implements  BeanALocalInterface {
        @EJB private BeanBLocalInterface beanBLocalInterface;
        public BeanA() {}
        public void executeLocal() {System.out.println("executing in  BeanA"); beanBLocalInterface.executeLocal();}
        public void executeRemote() {System.out.println("executing in  BeanA"); }
      }
      
      

       

      BeanBLocalInterface.java

       

      package com.xyz;
      import javax.ejb.Local;
      @Local
      public interface BeanBLocalInterface {
        public void executeLocal();
      }
      
      

       

      BeanB.java

       

      package com.xyz;
      import javax.ejb.EJB;
      import javax.ejb.Stateless;
      @Stateless
      public class BeanB  implements BeanBLocalInterface  {
        @EJB private BeanALocalInterface localInterface;
          public BeanB() {  }
          public void executeLocal() { localInterface.executeLocal(); }
        public void executeRemote() { System.out.println("executing in  BeanB");}
      }

        • 1. Re: Stateless Beans in ejb jar  working in Jboss 7.1  but not in Jboss  5.1
          jcmeena

          @IgnoreDependency annotation on injected Beans will resolve this issue. Please Modify BeanA.java and BeanB.java as follows:

           

          BeanA.java

           

          package com.xyz;
          import javax.ejb.EJB;
          import javax.ejb.Stateless;
          import org.jboss.ejb3.annotation.IgnoreDependency;
          @Stateless
          public class BeanA implements  BeanALocalInterface {
              @IgnoreDependency
              @EJB(name="ejb/BeanBLocalInterface")    private BeanBLocalInterface beanBLocalInterface;
              public BeanA() {}
              public void executeLocal() {System.out.println("executing in  BeanA"); beanBLocalInterface.executeLocal();}
              public void executeRemote() {System.out.println("executing in  BeanA"); }
          }
          

           

          BeanB.java

          package com.xyz;
          import javax.ejb.EJB;
          import javax.ejb.Stateless;
          import org.jboss.ejb3.annotation.IgnoreDependency;
          @Stateless
          public class BeanB  implements BeanBLocalInterface  {
              @IgnoreDependency
              @EJB(name="ejb/BeanALocalInterface ") private BeanALocalInterface localInterface;
              public BeanB() {  }
              public void executeLocal() { localInterface.executeLocal(); }
              public void executeRemote() { System.out.println("executing in  BeanB");}
          }
          

           

          I derived my solution from the following question answer link . https://developer.jboss.org/thread/110283?tstart=0
