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

客户端需要 JRE 才能运行 Java Web Start 应用程序，因为它在本地下载和执行，所有 Java 应用程序都需要安装 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 提供了声明 JRE(带有版本号)并在未安装时下载的选项.(但我从未使用过它，所以我不能告诉你如何设置它)在 wikipedia.

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.
