我在Windows中使用Net Beans创建了程序，它运行正常。当我将代码单独传输到HP-UX时，我遇到了以下错误。
对不起我的问题，我是java新手。
Exception in thread "main" java.lang.NoClassDefFoundError: javaapplication2/JavaApplication2
Caused by: java.lang.ClassNotFoundException: javaapplication2.JavaApplication2

Could not find the main class: javaapplication2.JavaApplication2. Program will exit.
编译代码给了我两个类：
JavaApplication2$1.class
JavaApplication2.class
MANIFEST.MF
Main-Class: javaapplication2.JavaApplication2
我还在class，manifest.mf和code所在的主目录中执行了jar命令。
/opt/java6/bin/jar -cvfm app.jar MANIFEST.MF *class
我想知道可能是遇到错误的原因。

答案 0 :(得分：0)
我只是通过删除包名来修复错误。
