Cyclically dependent Stateless beans in ejb archive jar not getting deployed on JBoss 5.1.0

Question

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");}
}

Answer 1

@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");}
}
