I work on my graduation project on 2 different computers, the problem is every time i copy from here to there i get endless errors and problems specifically with on submit servlets for example i have a registration form that takes registered user info through a servlet to another which connects it to another database, when i tried on one of the computers it worked fine but now as i took it home i get the The requested resource () is not available. error.
Here is the registration JSP form method and submit
<form name="myForm" action="RegisterUSER" onsubmit="return validateForm()"            method="post">
Here i have all the registration fields and drop boxes and at the ned i have this
   <input type="submit" value="Register" name="Register" />
   </br>
   </form>
And here is the servlet that it should submit to(the one netbeans cant find).
import java.io.*;
import java.net.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class RegisterUSER extends HttpServlet {
    protected static void processRequest(HttpServletRequest request, HttpServletResponse   response)
   throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        String First_Name=request.getParameter("FirstName");
        String Middle_Name=request.getParameter("MiddleName");
        String Last_Name=request.getParameter("LastName");
        String Username=request.getParameter("Username");
        String Email_Address=request.getParameter("EmailAddress");
        String Password=request.getParameter("Password");
        String Birth_date=request.getParameter("Birthdate");
       String ID=request.getParameter("ID");
    Connecttodatabase con=new Connecttodatabase();
    int x=0;
    try{
 x =con.insertusersToDatabase(First_Name, Middle_Name, Last_Name, Username, Email_Address, Password, Birth_date, ID);
    }
     catch(Exception e){
            System.err.println("Got an exception!");
            System.err.println(e.getMessage());
         }
out.println("<html>");
        out.println("<head>");
        out.println("<title>Servlet Registration</title>");
        out.println("</head>");
        out.println("<body>");
        request.getContextPath ();
       out.println("Registration Complete " +x);
       out.println(Username);
        out.println("</body>");

        out.close();
