答案可能取决于如何访问大型机系统。但是，请查看 JDBC界面 [ ^ ]可以为您提供解决方案。

 开发一个使用java和大型机的应用程序 

请注意，名称为大型机。我想你正在谈论你的应用程序的JFrame组件。



我会建议一个像样的 RMI连接 [ ^ ]（教程@ oracle.com）。这是有据可查的，经常使用。

The answer may depend on how the mainframe system is accessed. However, take a look at the JDBC interface[^] which may provide you with a solution.

Please be aware that the name "mainframe" is taken. I suppose you are talking about JFrame components of your application.

I would suggest a decent RMI Connection[^] (Tutorial @ oracle.com). That is well documented and often used.
