Just Need Some quick help with code

Ok,

Here goes im pretty new to java, but need to compile and run the following code. It's basicially a RMI Client Server which generates prime numbers


Here is the source Code

CLIENT

Code :

---

import java.rmi.Naming;
import java.rmi.RemoteException;
import java.net.MalformedURLException;
import java.rmi.NotBoundException;
import java.io.*;
public class PrimesClient
{
public static void main(String[] args)
{
try
{
if (args.length != 3)
{
System.out.println("Error usage: java PrimesClient host "
+" min max");
System.exit(0);
}
//look up the service in the registry
Primes c = (Primes) Naming.lookup("rmi://" + args[0] +
"/PrimesServd");
int ct;
int lct = 0;
int min = Integer.parseInt(args[1]);
int max = Integer.parseInt(args[2]);
int[] p = c.findPrimes(min, max);
ct = p[0];
for (int i = 1; i < ct; i++)
{
lct++;
if (lct == 12)
{
lct = 0;
System.out.println();
}
System.out.print(" " + p[i]);
}
System.out.println();
}
catch (Exception e)
{
System.out.println("Exception" + e);
System.out.println(e);
}
}
}

This is the error I receive in JCreator for Client Part
C:\Users\Tevez aka Ratman\Desktop\PrimesClient.java:19: cannot find symbol
symbol : class Primes
location: class PrimesClient
Primes c = (Primes) Naming.lookup("rmi://" + args[0] +
^

Primes c = (Primes) Naming.lookup("rmi://" + args[0] +

2 errors

Process completed.


SERVER

Code :

---

import java.rmi.Naming;
import java.rmi.RemoteException;
import java.rmi.RMISecurityManager;
import java.rmi.server.UnicastRemoteObject;
import java.rmi.registry.LocateRegistry;
public class PrimesServd extends UnicastRemoteObject implements
Primes
{
int[] p;
public PrimesServd() throws RemoteException
{
super();
p = new int[1000];
}
public int[] findPrimes(int min, int max) throws
java.rmi.RemoteException
{
int ct = 1;
for (int i = min; i < max; i++)
{
if (isPrime(i))
{
p[ct] = i;
ct++;
}
}
p[0] = ct;
return p;
}
private static boolean isPrime(int n)
{
int i;
for (i = 2; i * i <= n; i++)
{
if ((n % i) == 0)
{
return false;
}
}
return true;
}
public static void main(String args[])
{
if (args.length != 1)
{
System.out.println("Error! correct usage java
PrimesServd server-host");
}
else
{
try
{
// Create and install a security manager
//if (System.getSecurityManager() == null) {
//System.setSecurityManager(new
RMISecurityManager());
// }
PrimesServd sc = new PrimesServd();
Naming.rebind("rmi://" + args[0] + "/PrimesServd",
sc);
System.out.println("PrimesServd bound in registry");
}
catch (Exception e)
{
System.out.println(" Server err: " +
e.getMessage());
}
}
}
}

This is error I receive for client part

C:\Users\Tevez aka Ratman\Desktop\PrimesServd.java:46: unclosed string literal
System.out.println("Error! correct usage java
^
C:\Users\Tevez aka Ratman\Desktop\PrimesServd.java:46: ';' expected
System.out.println("Error! correct usage java

RMISecurityManager());
^
5 errors

Please could someone please tell me why its not functioning

Those compiler errors tell you exactly what line they are on and are simple java syntax errors. For example

Code :

---

System.out.println("Error! correct usage java
PrimesServd server-host");

---

should be

Code :

---

System.out.println("Error! correct usage java " + 
"PrimesServd server-host");

---
