B.4. relationships element

The relationships element specifies any number of associations between EJBs. It is optional, but will always be presented when there are container-managed associations. It has the following basic structure:

    <ejb–jar> 

      <enterpise–beans> 
       (... EJB configuration ...) 
 5    </enterpise–beans> 

      <relationships> 
        <ejb–relation> 
            <... association 1...> 
10      </ejb–relation> 
        <ejb–relation> 
            <... association 2...> 
        </ejb–relation> 
        <ejb–relation> 
15          <... association 3...> 
        </ejb–relation> 
        (... etc ...) 
      </relationships> 

20  </ejb–jar> 

that is, it consists of a number of ejb-relation elements.

The ejb-relation element specifies the source and destination of a relationship, and the mutliplicity of each end. Here is an example.

 <ejb–jar> <relationships> ...
