运行 Java Chrome 可以吗？ JNLP？

Question

我正在制作一个网站，我需要在上面安装一个 VNC 查看器。我已经在使用 Tight VNC，他们有一个 Java 查看器。此代码能够运行作为小程序，但 Chrome 和 Firefox 等现代浏览器不允许小程序。运行 Java 在 Chrome 上编码还有其他方法吗？

我听说有些浏览器支持 Java Web Start，但我认为 Chrome 不支持。如果 Chrome 谁能帮我把这个小程序转换成 JNLP 文件？

如果无法从 Chrome 到运行 Java，我有没有办法制作一个 link 来让用户打开该页面在 Internet Explorer 中？

Answer 1

Chrome 和 Firefox 都不支持 Java 小程序。您必须切换到 HTML5 或 flash.

Answer 2

Chrome 并且 Firefox 不久前放弃了 Java 支持。 Edge 一开始并不支持它。您可以从每个浏览器打开 .jnlp 文件（参见示例 here），但这就像打开您从 Internet 某处下载的任何可执行文件一样。查看上面的示例，看看它在每个浏览器中的行为。

If there is no way to run Java from Chrome, is there a way for me to make a link that will open the user to that page in Internet Explorer?

不，您不能切换浏览器。那将是一个很大的安全风险，你会在 macOS 或 linux 上做什么？

关于迁移到 webstart *racle 提供了一些支持here and here。
