rmi找不到stub。

[benny_2001_80]

我刚开始学rmi，按照书上编了一个例子，这个例子刚开始运行好好的，在两台机子上都测试通过（没有采用动态类加载，直接把相关文件拷到客户机）。我也不知道改了什么地方，有一次运行突然就不行了，启动server时报错：Remote Error -----java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
java.lang.ClassNotFoundException: RMILightBulbImp1_Stub

请高手指点！！

忘了一点，为了省事，我把所有的源文件和编译的.class文件放在一个目录下面，应该没问题吧。rmic后的stub和skelton也是在这个目录。关键是以前怎么测试没问题，突然就不行了？出问题是在本地机上运行cmd，用java LightBulbServer命令就报了上面所说的错误

我也遇到这个问题了，郁闷中

你要把它设知道类的路径里,如果cmd也在包所在的目录运行,classpath中至少要有一个.;
