我试图让一个名为 JTA 的插件在 JInternalFrame 中运行。我试过运行小程序版本并调用 Main.class 没有成功。
我被告知我不能使用 jInternalFrame.add(Object) 调用对象。当我尝试 de.mud.jta.Main main = new de.mud.jta.Main(); 时，我得到 NO SUITABLE METHOD FOR ADD 编译，错误指向 jDesktopPane1.add(main);
这是我所知道的：
Main.class 创建一个新的 JFrame。如果有某种方法可以让它填充我的 jInternalFrame 来代替制作一个新的就可以了。我也会对在我的应用程序的 DesktopFrame 中打开新的 JFrame 感到满意。在这一点上，我什至会接受一个全新的框架打开（某种弹出窗口）。
这是 Main.class 源代码：

* This software is written entirely in Java<SUP>tm</SUP>.<P>
* This is the main program for the command line telnet. It initializes the

我怎样才能让这个类运行，并让它创建的东西在我的应用程序的框架中运行？
