//=========================================================================

//=============================================================================
public class gameScreen extends GameCanvas implements Runnable,CommandListener

WTK2.2 Build编译通过，运行时候提示ClassNotFoundException错误 提示说找不到gameScreen/class 但是我在src目录下找的到gameScreenClass啊 奇怪

启动类写错了
不要写.class后缀
启动类的地方,直接写类名
另外,你的启动类不止多写了后缀,似乎连名字都写错了
启动类必须是MIDlet的子类

我也有这份代码 启动类错了

新手写的吧
