如何启动 java-web-start 应用程序并等待它退出? [英] How to start a java-web-start application and wait until it exits?

问题描述

我刚刚发现 javaws -wait 不能执行在 Windows 上应该执行的操作.它将在申请完成之前返回.

I just found out that javaws -wait doesn't do what is supposed to do on Windows. It will return before the aplication finishes.

这个错误已经超过 5 年了，因为无法修复而关闭6281477，所以我们需要一个解决方法.

This bug is more than 5 years old and closed as won't fix 6281477, so we need a workaround.

我正在寻找一个干净的解决方案:

I looking for a clean solution that will:

• 无人值守运行(无需用户干预):
  • 目前如果 JNLP 文件不可访问，Java 将显示一个错误窗口.

  最好为此 Java 或 Python 提供跨平台解决方案，但即使是 Windows 批处理解决方案也是可以接受的.

  It would be preferable to have a cross platform solution for this Java or Python but it would be acceptable even a Windows batch solution.

  推荐答案

  我知道这个问题很老了，但这里有一个 javaws -wait 的替代方案:javaws将启动一个 javaw 进程，以 com.sun.javaws.Main 作为主类.

  I know this question is pretty old, but here is an alternative to javaws -wait: javaws will start a javaw process with com.sun.javaws.Main as main class.

  jcmd 可以派上用场:

  while jcmd com.sun.javaws.Main PerfCounter.print > /dev/null 2> /dev/null  ; do
    echo "still running !"
    sleep 2
  done
  

  这样做的一个缺点是确定实际的 java cmd:如果运行了多个 webstart 应用程序，那么只有当所有应用程序都关闭时，该命令才会退出.

  One down side of this is to determine the actual java cmd: if multiple webstart application are ran, then the command will exit only if all application are down.
