Java Webstart "javaws -open" 标志不适用于多个参数

Java Webstart "javaws -open" flag doesn't work with multiple arguments

我正在尝试调用 Java Webstart,它使用“-open”运行 时间选项向 webstart 应用程序发送参数。我已经引用了这个问题:Passing command line arguments to javaws (Java WebStart) executable,但这种语法似乎不适用于多个参数。不过,它似乎可以找到一个参数。

当我 运行 "javaws URLtoMyJNLP" 它 运行 应用程序正常时,当我通过 "javaws -open arg URLtoMyJNLP" 发送单个参数时它似乎也有效并且 arg 得到到应用程序。当我尝试 运行 "javaws -open arg arg arg URLtoMyJNLP" 时,它说提供的参数无效。我将命令输入 ProcessBuilder.command.

InvalidArgumentException[ Invalid arguments supplied: {hello, jnlp, launch.jnlp, 123 }]

对于上面的输出,我尝试发送 "javaws -open abc 123 hello launch.jnlp"

有什么想法吗?

按要求编码。由于是 PoC,因此过于简单。

private static void launchApp(String appName, String appPath, String... args)
{
    logger.debug("Launching application: " + appName);

    Properties props = System.getProperties();
    ArrayList<String> fullCmdString = new ArrayList<String>();

    logger.debug("http://" + System.getProperty("jnlp.serverip") + ":" + System.getProperty("jnlp.serverport") + "/FB2HMI/" + appPath);

    if (args.length > 0)
    {
        fullCmdString.add("javaws");
        fullCmdString.add("-open");
    }
    for (String arg : args)
    {
        fullCmdString.add(arg);
    }

    fullCmdString.add("http://" + System.getProperty("jnlp.serverip") + ":" + System.getProperty("jnlp.serverport") + "/FB2HMI/" + appPath);
    logger.debug("Command = " + fullCmdString);
    ProcessBuilder rmLauncher = new ProcessBuilder().command(fullCmdString.stream().toArray(String[]::new));
    Process p;
    try
    {
        p = rmLauncher.start();

        processList.add(p);
        logProcessOutput(p, logger, null, appName);
    }
    catch (Exception e)
    {
        logger.fatal("Failed to launch " + appName + ": " + e);
        System.exit(1);
    }

}

这可能是一个丑陋的答案,但由于这个问题还没有任何正确的答案,我将向您展示我的解决方法。将参数作为环境变量传递到 JVM。这将需要编辑源应用程序以查找环境变量作为参数的替代方法,但这是我发现甚至可以远程工作的解决此 webstart 问题的唯一方法。

Map<String, String> saArgs = new HashMap<String, String>();
saArgs.put("jnlp.serverip", System.getProperty("jnlp.serverip"));
saArgs.put("jnlp.serverport", System.getProperty("jnlp.serverport"));
saArgs.put("port", "8887");
saArgs.put("surfaceip", "192.168.0.50");

ProcessBuilder rmLauncher = new ProcessBuilder().command(fullCmdString.stream().toArray(String[]::new));
    Process p;

    for (Map.Entry<String, String> entry : args.entrySet())
    {
        rmLauncher.environment().put(entry.getKey(), entry.getValue());
    }

    try
    {
        p = rmLauncher.start();
     }
    catch (Exception e)
    {
        logger.fatal("Failed to launch " + appName + ": " + e);
        System.exit(1);
    }

JAR 应用程序内部:

    logger.debug("jnlp.serverip = " + env.get("jnlp.serverip"));
    logger.debug("jnlp.serverport = " + env.get("jnlp.serverport"));
    logger.debug("port = " + env.get("port"));
    logger.debug("surfaceip = " + env.get("surfaceip"))
