Problem in placing files in server

Question

Hello,
I am working on applet to servlet communication. I have developed the code but I have problem in placing the files in the tomcat server. these are my files
test.html
test.class (applet)
inter.class (bean implementing serializable interface)
testser.class (servlet)
I have placed test.html, test.class and inter.class in webapps/examples folder. I have placed testser.class in webapps/examples/web-inf/classes folder.
So that i can now see the applet and applet pass values to bean. But my servlet is not called. Can any one help what is going wrong or where should i place the files?
Thanks

Hello,
Here goes my source code files. All of them are working source files,
I am a bit confused in placing them in the Tomcat server. Can anyone try and post the results please?
i.e placing the files in the proper directories of the server.
// Register.java
import java.sql.*;
public class Register implements java.io.Serializable
    // data members
    private String firstname;
    private String lastname;
    private final String CR = "\n";     // carriage return
    // constructors
    public Register()
    public Register(String afirstName, String alastName)
        firstname = afirstName;
        lastname = alastName;
          RegistrationServlet regser = new RegistrationServlet();
     public String getFirstName()
             System.out.println("In getFirstName(): " + firstname);
          return firstname;  
    public String getLastName()
        return lastname;
