请教用jbuilder开发ejb，发布时连数据源的jndi一起发布问题

[winespirit]

我用jb9＋jboss3开发ejb，在ejb module里面配置好了ejb bean和数据源（oracle）的jndi(jdbc/mydb)，测试连接通过（jb上面有按钮），然后发布运行，但是在测试运行到 ds = (DataSource)ctx.lookup("jdbc/mydb");的时候，系统报错：
javax.naming.NameNotFoundException: jdbc not bound

换过了java;/jdbc/mydb也不行，后来将jndi名称改为mydb，用java:/mydb访问也报同样错误。
请问这是为什么？是我配置数据源出了问题，还是发布出了问题，还是访问时出了错呢？

[winespirit]

如何能够让jbuilder在将整个ejb module发布的时候连数据源一起发布呢？数据源是包含在ejb模块内部的，在设计视图那儿。

问题是你在web.xml中配置数据源了么？或者在应用服务器对应的相应的配置文件中。
