netbeans - 64位Win 7平台上的JavaFx应用程序

Question

我在桌面上编写了一个JavaFx应用程序(基于JavaFx Windows的表单)运行

1. Win 7 32 位
2. Netbeans 7.3 测试版
3. jdk-7u9-windows-i586

并且运行成功。

我最近运行了一台笔记本电脑

1. Win 7 64 位
2. Netbeans 7.3 测试版
3. jdk-7u9-windows-x64

我刚刚复制了代码并切换了 Java 平台...目前其设置为默认的“默认 JavaFx 平台”。

如果我运行该应用程序，我会收到以下错误对话框

JavaFx 启动器错误 - 运行应用程序时出现异常

任何人都知道我需要在这里更改什么...

Answer 1

根据java.lang.ClassNotFoundException: co.za.chrispie.LoginController判断，您在复制时错过了一些代码或依赖库。

找到负责类co.za.chrispie.LoginController的java或jar文件并确保:

• 它存在于您的笔记本电脑上
• 它位于正确的包位置
• 它包含在您的新项目(源文件夹)中
