我正在用 JavaFX 制作一个简单的游戏，但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 脚本应用程序”。

当我构建项目时，它会在文件夹中创建四个文件dist。这些是：

  • BcJavaFX.html文件
  • BcJavaFX.jar文件
  • BcJavaFX.jnlp文件
  • BcJavaFX_browser.jnlp文件

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. 随着BcJavaFX_browser.jnlp游戏在浏览器中运行。随着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。当我将鼠标悬停在感叹号上时，会显示文本“Java 应用程序窗口”。但应用程序运行正常。

问题是该应用程序无法在其他计算机上运行。当我打开文件BcJavaFX.jnlp或BcJavaFX_browser.jnlp在其他计算机上时，会显示一个窗口，其中显示消息“无法启动应用程序”。异常详情如下：

但是当我启动一个国外下载的游戏（例如http://www.remwebdevelopment.com/javaFX-game-tutorial/Blasteroids.zip）时，游戏在所有电脑上都能正常运行。请问哪里有问题？
