Java 从Flex调用jar文件命令

我正在尝试从AIR应用程序调用.jar文件。我们可以通过

NativeProcess

来实现这一点。我的代码是下一个

请在这方面帮助我。

通常我们不能直接运行JAR文件，所以在这里我们通过命令提示符运行。然后找到cmd.exe路径，然后只需按照下面的代码执行即可。只有在运行MacOS然后执行shell脚本（.sh）时，它才适用于windows

确保您需要在应用程序描述符XML文件中添加

extendedDesktop

还要确保在环境变量中指定java类路径

jaganath，谢谢你的回复。它很有效，但就我所知，我想知道你为什么使用processArgs.push（“/c”）作为参数？
