如何检测安装在客户端上从ASP .NET网站上的Java运行时? [英] How can I detect the Java runtime installed on a client from an ASP .NET website?
问题描述
我有一个ASP .NET网站承载的Java小程序。 Java小程序需要Java运行时的1.6版更新11。
I have an ASP .NET website that hosts a Java applet. The Java applet requires version 1.6 Update 11 of the Java runtime.
我怎样才能检测到客户端有相应的运行时安装的,这样,如果他们不这样做,我可以显示一条提示消息?
How can I detect that a client has the appropriate runtime installed so that I can display an informative message if they do not?
谢谢,
卡尔。
编辑:解决方案必须是独立的平台。
The solution must be platform independant.
