How I can compile a ejb3 class to a idl file by the weblogic.rmic command.

Question

Now, I want create a idl file from a ejb3 class by the weblogic.rmic command.
I had written a sample case. but when I compile, I get a [Class not found] error, why?
Who can guide me or provide me with a sample?
There is a my sample code, below.

Thanks for your replay.
Before I set the classpath, I had met the ClassNotFound problem.
My command : java -cp %WEBLOGIC_SERVER%\lib\weblogic.jar weblogic.rmic -idl ejbModule.hello.Hello
I was afraid to lost the class that the weblogic.rmic is required, I set the classpath(java library path/class ,weblogic library path/class).
I think the class what is not found is like my class(hello), not the class of the weblogic or java.
Now I don't know what is requred by weblogic.rmic. Is it a class or source of "Hello", and the package name of "Hello" is requred?
After the idl option is cut, when I execute the Command[java weblogic.rmic *---idl--* ejbModule.hello.Hello], I got the other error, below.
(*the Hello class is in ejbModule.jar)
C:\CORBA\test>java weblogic.rmic ejbModule.hello.Hello

ejbModule.hello.Hello must be a remote interface implementation and should exist in the classpath
