这是我的第二个问题，希望这次有人能回答。我正在使用 weblogic 10 和 EJB 2，但现在我要在 Spring 3 中创建一个新模块。
一切正常，但我无法在 spring 上下文 xml 中使用 JNDI 提供的现有数据源对象 ....
这是文件
Weblogic 配置.xml
<jdbc-system-resource>
<name>EOrderDataSource</name>
<target>adeccoClubServer</target>
<descriptor-file-name>jdbc/EOrderDataSource-jdbc.xml</descriptor-file-name>
</jdbc-system-resource>
<jdbc-system-resource>
EOrderDataSource-jdbc.xml

<jndi-name>EOrderDataSource</jndi-name>
<global-transactions-protocol>EmulateTwoPhaseCommit</global-transactions-protocol>
</jdbc-data-source-params>
</jdbc-data-source>
还有我的调度员 servlet

具有手动连接的 Dispatcher Servet，工作正常

即使在 Java 端，获取数据源对象也非常简单，并且工作正常：
Context ctx = new InitialContext ();
DataSource ds = (DataSource) ctx.lookup ("EOrderDataSource");
