我一直在网站和互联网上搜索如何将使用GUI的java程序转换为applet。我已经找到了一般教程，比如基本程序，但是我使用OpenCV（http://opencv.org/）来生成图像，然后JFrame将其转换为GUI。我已设法将所有代码放入一个类文件中，以便我可以对其进行修改，以使其像applet一样运行（例如摆脱＆＃34; main＆＃34;方法和使用public void init（）），然后有整个尝试将其放入HTML代码的过程，我只尝试直接标记，并尝试创建一个jar文件并将其与deployJava.js一起使用（java部署小程序的脚本）。我已经设法从浏览器页面中获取任何东西。我只需要加载html页面就可以运行它，最多只需点击一个按钮（但仅在必要时）。从未发现的异常到安全异常，再到InvocationTargetException。那么如何帮助我将这个程序放到网上呢？

修改

这是.jnlp
