麻烦看下到底是什么问题

Question

为什么我用JBulid9生成一个exe文件没有出错
而在dos下用javac 命令编译那些文件 出现 cannot find symbol：symbol class：xxx（文件名）
用JBulid运行一点问题都没啊麻烦帮我看下吧 谢谢了

Answer 1

答：根据我的经验，很可能是程序中用到了JBuilder中带有的类库。你将用到的JB的类库文件如：***.jar加到classpath中，应该就行了。以上仅供你参考

5 errors这个是编译时的错误

Answer 4

先谢了 我好像没用到JBuilder中的类库 麻烦你看下了

Answer 5

答：你的程序中这两个类都没有定义啊：FanChat、UserInfo。定义过了就行了。

Answer 6

定义了都 所以才奇怪 因为在JBulid中运行没问题的

Answer 7

你可能用到了JBuilder的类库了
