请教jboss 4.0 编写CMP entitybean 中的数据库关系映射问题

[riceconjee_chy]

各位大侠，经典的Order-Shipment关系是一个one-to-one问题，我是如此配置ejb-jar.xml：
<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar id="ejb-jar_ID" version="2.1"
xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

请问如何配置jbosscmp-jdbc.xml文件？我的配置肯定不对，需要在哪些地方改进？
