Hvis det hjælper forsøger vi således mellem File og Info Entity Beans, hvor der er en mange til mange forhold :

    File:
    /**
    * @ejb.interface-method
    *    view-type="local"
    *
    * @ejb.relation
    *    name="File-Info"
    *    role-name="File-has-Info"
    *    target-ejb="Info"
    *    target-role-name="Info-has-File"
    *
    *
    * @jboss.relation
    *    fk-column="infoid"
    *    related-pk-field="id"
    *
    * @jboss.relation-table
    *    table-name="fileinfo"
    *    create-table="true"
    *    remove-table="true"
    *
    */
    public abstract java.util.Collection getInfo(); 


    Info:
    /**
    * @ejb.interface-method
    *    view-type="local"
    *
    * @ejb.relation
    *    name="Info-File"
    *    role-name="Info-has-File"
    *    target-ejb="File"
    *    target-role-name="File-has-Info"
    *
    *
    * @jboss.relation
    *    fk-column="fileid"
    *    related-pk-field="id"
    *
    * @jboss.relation-table
    *    table-name="fileinfo"
    *    create-table="true"
    *    remove-table="true"
    */
    public abstract java.util.Collection getFiles();


Men vi får denne fejl:

Du har givet din relation to forskellige navne, både "File-Info" og "Info-File". Role name er muligheden for at navngive de to forskellige veje i relationen forskelligt.
