但是使用many to one 则没有问题,真是奇怪啊!

one to one时的文件如下:

weblogic-cmp-extras.xml
<weblogic-rdbms-relation>
<relation-name>orderlineitems-products</relation-name>
<weblogic-relationship-role>
<relationship-role-name>ProductsRelationshipRole</relationship-role-name>
<column-map>
<foreign-key-column>PRODUCTID</foreign-key-column>
<key-column>PRODUCTID</key-column>
</column-map>
<relationship-role-map>
<foreign-key-table>PRODUCTS</foreign-key-table>
<primary-key-table>ORDERLINEITEMS</primary-key-table>
<column-map>
<foreign-key-column>PRODUCTID</foreign-key-column>
<key-column>PRODUCTID</key-column>
</column-map>
</relationship-role-map>
</weblogic-relationship-role>
</weblogic-rdbms-relation>

weblogic-cmp-rdbms-jar.xml

<weblogic-rdbms-relation>
<relation-name>orderlineitems-products</relation-name>
<weblogic-relationship-role>
<relationship-role-name>ProductsRelationshipRole</relationship-role-name>
<relationship-role-map>
<foreign-key-table>PRODUCTS</foreign-key-table>
<primary-key-table>ORDERLINEITEMS</primary-key-table>
<column-map>
<foreign-key-column>PRODUCTID</foreign-key-column>
<key-column>PRODUCTID</key-column>
</column-map>
</relationship-role-map>
</weblogic-relationship-role>
</weblogic-rdbms-relation>

many to one 时的文件如下:

weblogic-cmp-extras.xml
<weblogic-rdbms-relation>
<relation-name>orderlineitems-products</relation-name>
<weblogic-relationship-role>
<relationship-role-name>OrderlineitemsRelationshipRole</relationship-role-name>
<column-map>
<foreign-key-column>PRODUCTID</foreign-key-column>
<key-column>PRODUCTID</key-column>
</column-map>
<relationship-role-map>
<foreign-key-table>ORDERLINEITEMS</foreign-key-table>
<primary-key-table>PRODUCTS</primary-key-table>
<column-map>
<foreign-key-column>PRODUCTID</foreign-key-column>
<key-column>PRODUCTID</key-column>
</column-map>
</relationship-role-map>
</weblogic-relationship-role>
</weblogic-rdbms-relation>

weblogic-cmp-rdbms-jar.xml
<weblogic-rdbms-relation>
<relation-name>orderlineitems-products</relation-name>
<weblogic-relationship-role>
<relationship-role-name>OrderlineitemsRelationshipRole</relationship-role-name>
<relationship-role-map>
<foreign-key-table>ORDERLINEITEMS</foreign-key-table>
<primary-key-table>PRODUCTS</primary-key-table>
<column-map>
<foreign-key-column>PRODUCTID</foreign-key-column>
<key-column>PRODUCTID</key-column>
</column-map>
</relationship-role-map>
</weblogic-relationship-role>
</weblogic-rdbms-relation>

高手救命啊
我不知道primary-key-table 和 foreign-key-table 有什么作用?
