Second question: Is there a feature in Java web start to check for an installed JRE and automatically setup the environment?

推荐答案

在客户端上需要JRE来运行Java Web Start应用程序，因为它是在本地下载和执行的，并且所有Java应用程序都需要已安装的JRE.

a JRE is required on the client to run your java Web Start application as it is downloaded and executed localy and all Java applications need an installed JRE.

Java Web Start提供了一个选项，用于声明JRE(具有版本号)并下载(如果未安装). (但我从未使用过它，所以我无法告诉您如何设置)，位于维基百科.

Java Web Start provides the option to declare a JRE (with version number) and download it if it is not installed. (But I never used it so I can't tell you how to set this up) found on wikipedia.
