Why cann't rmic find the class?

Question

I have write some RMI Code,and I could compile them correctly,but when I wanted to generate Stub and Skel by rmic ,it showed me that:
E:\JavaPro\CH21-05>rmic RmiTestServer
error: Class RmiTestServer not found.
1 error
I don't know why?
Here the source which helps to understand the problem:
//Code in RmiTest.java
import java.rmi.*;
public interface RmiTest extends java.rmi.Remote
     //Definate an interface from java.rmi.Remote
     public float getRmiTest(int r) throws RemoteException;
//Code in RmiTestServer.java
import java.rmi.*;
import java.rmi.server.UnicastRemoteObject;
import java.lang.Math;
public class RmiTestServer extends UnicastRemoteObject implements RmiTest
     //load the constructor of UnicastRemoteObject
     RmiTestServer()throws RemoteException
          super();
     //The client will send the parameters to here,and calculate,and get the results back
     public float getRmiTest(int r)throws RemoteException
          float circlerate=(float)(2*Math.PI*r);
          return circlerate;
     public static void main(String args[])
          try
               Naming.rebind("//127.0.0.1:1099/RmiTestObj",new RmiTestServer());
               System.out.println("RMI Connecting...");
          catch(Exception e)
               System.out.println("RMI can't connect... :"+e);
               System.exit(-1);
//Code in RmiTestClient.java
import java.awt.*;
import java.rmi.*;
public class RmiTestClient
     public static void main(String args[])
          float circlerate=(float)0.0;
          try
               //Set security manager according to security mechanism
               System.setSecurityManager(new RMISecurityManager());
               //Query remote object,and it's host address is 127.0.0.1 ,and it's port is 1099
               //RmiTestObj is a byname of RMI logging on
               RmiTest obj=(RmiTest)Naming.lookup("//127.0.0.1:1099/RmiTestObj");
               //method to load remote object
               circlerate=obj.getRmiTest(5);
               //print the result
               System.out.println("Total circlerate is : "+circlerate);
          catch(Exception e)
               System.out.println(e.getMessage());
How can I solve this problem?

Answer 1

I made it by runing the following command line:
rmic -classpath E:\JavaPro\CH21-05 RmiTestServer
and it created two files: RmiTestServer_Skel.class and RmiTestServer_Stub.class
Thank you very much!
