你可以在Chrome上运行Java吗？ JNLP？

Question

我正在制作一个网站，我需要有一个VNC浏览器。我已经使用了Tight VNC，他们有一个Java查看器。此代码可以作为applet运行，但现代浏览器（如Chrome和Firefox）不允许小程序。有没有另一种方式在Chrome上运行Java代码？

我读过一些浏览器支持Java Web Start，但我不认为Chrome会。如果Chrome能够帮助我将这个小程序转换为JNLP文件吗？

如果你想.jar文件是在http://www.tightvnc.com/download.php

下载如果没有办法从Chrome中运行Java，有没有为我做一个链接，将打开用户的方式Internet Explorer中的那个页面？

Answer 1

前段时间Chrome和Firefox都放弃了对Java的支持。 Edge并不支持它开始。您可以从每个浏览器中打开.jnlp文件（请参阅示例here），但它好像打开从互联网上下载的任何可执行文件。看看上面的例子，看看它们在每个浏览器中的行为。

如果没有办法从Chrome运行Java，有没有办法让我建立一个链接，将用户打开到Internet Explorer中的那个页面？

不，您不能切换浏览器。这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和here。

Answer 2

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