部署实体bean到weblogic8的时候出错：Null keys not supported.Nested Exception: java.lang.IllegalArgumentException: Null keys not s

Question

应该是：<prim-key-class></prim-key-class>有问题；
给你一个参考：
<entity>
            <display-name>AccountBean</display-name>
            <ejb-name>AccountBean</ejb-name>
            <home>ejbdemo.AccountHome</home>
            <remote>ejbdemo.Account</remote>
            <local-home>ejbdemo.AccountLocalHome</local-home>
            <local>ejbdemo.AccountLocal</local>
            <ejb-class>ejbdemo.AccountBean</ejb-class>
            <persistence-type>Bean</persistence-type>
            <prim-key-class>ejbdemo.AccountPK</prim-key-class>
            <reentrant>False</reentrant>
</entity>

Answer 1

ejb-jar.xml文件是jbuilder自动生成的，我没有作任何更改。
我是在datasources上右击import schema from database, 在出现的student表上create cmp 2.0，然后没有做任何事情，直接make和deploy就报错！
