EJB问题高分请教！！急！CMR的外键可不可以再加入到CMP中？我用的是Websphere！

我在JBOSS里配置过,如下
在ejb-jar.xml里添加如下培植是表Customer:id(PK)
Addr:customerid(FK)
之间的映射
  <ejb-relation>
      <ejb-relation-name>Customer-Addr</ejb-relation-name>
   
      <ejb-relationship-role> 
         <ejb-relationship-role-name>
            customer-addresses
         </ejb-relationship-role-name>
   
         <multiplicity>One</multiplicity> 
   
         <relationship-role-source>
            <ejb-name>Customer</ejb-name> 
         </relationship-role-source> 
               
         <cmr-field>
         <cmr-field-name>addr</cmr-field-name> 
            <cmr-field-type>java.util.Collection</cmr-field-type> 
         </cmr-field>   <key-fields>
            <key-field>
               <!-- 在这里培植映射关系 -->
               <field-name>id</field-name>
               <column-name>customerid</column-name>
            </key-field>
         </key-fields>
      </ejb-relationship-role> 
   
      <ejb-relationship-role> 
         <ejb-relationship-role-name>
             addresses-customer
         </ejb-relationship-role-name>
               
         <multiplicity>Many</multiplicity> 
         <cascade-delete/>
               
         <relationship-role-source>   
            <ejb-name>Addr</ejb-name> 
         </relationship-role-source> 
      </ejb-relationship-role> 
   </ejb-relation>如上,在Websphere里行不行就不敢打包票了,呵呵
