无法启动应用程序

Question

我在JavaFX中制作了一个简单的游戏，我在运行应用程序时遇到了问题。我使用NetBeans 6.9.1。应用程序类型是“JavaFX Script Application”。

当我构建项目时，它会在文件夹dist中创建四个文件。这些是：

• BcJavaFX.html档案
• BcJavaFX.jar档案
• BcJavaFX.jnlp档案
• BcJavaFX_browser.jnlp档案

在我正在开发此游戏的计算机上，游戏在打开BcJavaFX.jnlp或BcJavaFX_browser.jnlp后运行。使用BcJavaFX_browser.jnlp游戏在浏览器中运行。使用BcJavaFX.jnlp游戏在经典窗口中运行。窗口右上角旁边是一个小感叹号。当我用鼠标悬停在感叹号上时，文本“Java Application Window”被显示。但应用程序运行正常。

问题是应用程序无法在其他计算机上运行。当我在其他计算机上打开文件BcJavaFX.jnlp或BcJavaFX_browser.jnlp时，会显示一个窗口，其中显示消息“无法启动应用程序”。例外情况包括：

但是当我开始一个外国下载的游戏（例如http://www.remwebdevelopment.com/javaFX-game-tutorial/Blasteroids.zip）时，游戏在所有计算机上都能正常运行。请问哪里有问题？
