Hello, i dont understand why i get the cant resolve symbol error.

I want to start an RMI server here.

import java.rmi.*;
import java.rmi.server.*;

public class PatientServer
{

   public static void main(String[] args)
   {
       try
       {
           if (System.getSecurityManager() == null)
           {
               System.setSecurityManager ( new RMISecurityManager());
           }
           Patient p = new Patient();       //////// the constructor
           System.out.println("Binding...");

               Naming.bind("PatientServer", p);
           System.out.println("PatientServer is ready...");

       }
       catch (Exception e)
       {
           e.printStackTrace();
       }
   }

}

Now i have a Patient Class where the constructor exists public Patient(int
patientNummer). So i dont understand why it will not initialize the
constructor. Patient.Class exists in the same package. I get this error
always: symbol  : constructor Patient ()
location: class sapa.Patient
           sapa.Patient p = new Patient();

Can somebody help me please. Even i want to send the code, and you can take
a look, also for payment if neccesary, becouse i cant get it to work and i
want to learn it so badly,

Thanks in advance

Irlan
