Benq:你好！

　　我这个EJB是容器管理持久性！对应Student表(id Number,name varchar2(12),sex varchar2(2)),jbuilder9自动生成的weblogic-cmp-rdbms-jar.xml文件如下:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE weblogic-rdbms-jar PUBLIC '-//BEA Systems, Inc.//DTD WebLogic 7.0.0 EJB RDBMS Persistence//EN' 'http://www.bea.com/servers/wls700/dtd/weblogic-rdbms20-persistence-700.dtd'>
<weblogic-rdbms-jar>
    <weblogic-rdbms-bean>
        <ejb-name>Student</ejb-name>
        <data-source-name>DataSource</data-source-name>
        <table-map>
            <table-name>STUDENT</table-name>
            <field-map>
                <cmp-field>id</cmp-field>
                <dbms-column>ID</dbms-column>
            </field-map>
            <field-map>
                <cmp-field>name</cmp-field>
                <dbms-column>NAME</dbms-column>
            </field-map>
            <field-map>
                <cmp-field>sex</cmp-field>
                <dbms-column>SEX</dbms-column>
            </field-map>
        </table-map>
    </weblogic-rdbms-bean>
</weblogic-rdbms-jar>


2.weblogic-ejb-jar.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE weblogic-ejb-jar PUBLIC '-//BEA Systems, Inc.//DTD WebLogic 7.0.0 EJB//EN' 'http://www.bea.com/servers/wls700/dtd/weblogic-ejb-jar.dtd'>

                <persistence-use>
                    <type-identifier>WebLogic_CMP_RDBMS</type-identifier>
                    <type-version>6.0</type-version>
                    <type-storage>META-INF/weblogic-cmp-rdbms-jar.xml</type-storage>
                </persistence-use>
            </persistence>
        </entity-descriptor>
        <local-jndi-name>Student</local-jndi-name>
    </weblogic-enterprise-bean>
</weblogic-ejb-jar>

3：　　ejb-jar.xml如下:

            <cmp-version>2.x</cmp-version>
            <abstract-schema-name>Student</abstract-schema-name>
            <cmp-field>

            </cmp-field>
            <cmp-field>
                <field-name>name</field-name>
            </cmp-field>
            <cmp-field>
                <field-name>sex</field-name>
            </cmp-field>
            <primkey-field>id</primkey-field>
        </entity>
    </enterprise-beans>
    <assembly-descriptor>
        <container-transaction>
            <method>
                <ejb-name>Student</ejb-name>
                <method-name>*</method-name>
            </method>
            <trans-attribute>Required</trans-attribute>
        </container-transaction>
    </assembly-descriptor>
</ejb-jar>

以下三个文件都是由jbuilder9自动生成！不知有什么错误?谢谢！
