Problems running standalone java

Question

I have been writing java applets for a while in editplus then compiling them with javac in editplus and viewing them with appletviewer through editplus. I have been given a java standalone program. It compiles fine with no error messages but when i try to run it with java i get the following error message:
java.lang.NoClassDefFoundError: Server1
Exception in thread "main"
Output completed (2 sec consumed) - Normal Termination
And the program doesn't run. Can anyone see why this is?
Any help will be greatly appreciated!

Answer 1

okay how would i go about correcting this problem?
Heres the code by the way:
import java.net.*;
import java.io.*;
public class Server1 {
public static void main(String [] args) {
ServerSocket s;
Socket clientsSocket;
try {
          s = new ServerSocket(5155);
          clientsSocket = s.accept();
          System.out.println(clientsSocket.getLocalAddress());
          System.out.println(clientsSocket.getInetAddress());
          System.out.println(clientsSocket.getPort());
          System.out.println(clientsSocket.getLocalPort());
          OutputStream out = clientsSocket.getOutputStream();
          InputStream in = clientsSocket.getInputStream();
          byte sendBuffer[] = {1, 2, 3, 4, 5, 6, 7, 8};
          out.write(sendBuffer);
          byte receiveBuffer [] = new byte [50];
          int lengthReceived = in.read(receiveBuffer);
          System.out.println("Received: " + lengthReceived + " bytes.");
          for (int i=0; i<lengthReceived; i++)
          System.out.println((char)receiveBuffer[i] + "\n");
          clientsSocket.close();
     catch (java.io.IOException e) { System.out.println(e.toString()); }
