我已经阅读了有关如何执行此操作的材料，但我一直试图弄清楚如何在浏览器模式或 webstart 模式下将参数传递给我的 JavaFX2 应用程序。
我也在这里在 OTN 论坛上问过这个问题

所以我将 ColorfulCircles 项目从 Ensemble 导入到 Netbeans。然后我修改了代码并放入了一个小片段以在 init 方法之后提取一个参数，就像这样。我只是获取参数并将其设置为舞台的标题。

                @Override public void start(Stage primaryStage) throws Exception {
                init(primaryStage);

                Parameters params = getParameters();
                String myTitle = params.getNamed().get("myTitle");
                primaryStage.setTitle(myTitle);

                primaryStage.show();
                play();
                }

然后我做了一个清理并在netbeans中构建......所有的html、jar、jnlp等都生成了。

然后我手动修改了 HTML，如下所示。但是对于任何一种模式，舞台的标题都不会更新/显示。这里缺少什么？

这已在 JavaFX 2.2 中修复，您可以在此处尝试开发人员版本：http ://www.oracle.com/technetwork/java/javafx/downloads/devpreview-1429449.html

但请确保使用新的 ant-javafx.jar 重新生成 html/jnlp 文件（或从示例中复制它们）
