Spring Converter - cyclic issue

I have a issue where, I have a converter class say called aConverter as such:

@XmlRootElement(name = "aConverter")
public class aConverter implements ConverterBase{

      private A a;
      private Set<B> bs;
      /// some constructor code here
      ...
      @XmlElement(name="B")
      public Set<B> getBs() {
                bs = a.getBs();
                return bs;
      }

      public void setBs(Set<B> bs) {
                a.setBs(bs);
      }
}

Class A and B are defined respectively in a cyclic fashion:

public class A {
       private Set <B> bs;

       //constructor code here
       ... 

       public Set<B> getBs() {
          return this.bs;
       }
       public void setBs(Set<B> bs) {
          this.bs = bs;
       }
}

>

public class B {
       private A a;

       // some constructor code here
       ...

       public A getA() {
              return this.a;
       }
       public void setA(A a) {
              this.a = a;
       }
}

Now, when I the webservice I'm seeing the following error:

[com.sun.istack.internal.SAXException2: A cycle is detected in the object graph.

I'm really out of ideas here, any feeback on this would be really nice.

Cheers!

In EclipseLink JAXB (MOXy) we introduced the @XmlInverseReference extension to solve this issue. For an example of how this can be leveraged in a JAX-RS service check out:

You can use @XmlTransient annotation. See this page for more.
