高手！！！！过来解决Applet运行环境的安装问题！！！

[rocsoar]

如何让Java Runtime Environment自动运行？？？？
如果以前安装的是低版本的Java Runtime Environment，而当前Applet所需的运行环境高，如何让Java Runtime Environment自动升级？？？

[littlecpu]

行吗？不如你在Applet里检查(system.getproperty())一下，不够高的话出个链接让客户下吧。
这个东东又不是flash

[rocsoar]

有没有什么解决方案呢？
客户浏览该Applet时，如果不安装JRE，那就看不了该Applet，看不了该Applet，那我做的Applet岂不是白费？
唉，Java不至于如此让我们程序员这般为难吧？

楼上的对!

[gaoxin900]

必须安装 JRE

[司码君]

这个的关键应该在html文件里面吧
如果你做好了html那就不用担心jre的问题了看看这个对你有没有用
