This tip shows how to read messages from a news server.

 import sun.net.nntp.*;
import java.io.*;

public class NntpGetGroup {
  public static void main(String[] args) 
    throws IOException {
    /*
    ** pass your news server, newsgroup  as parameter 
    **     eg. java NttpPost news.server.com alt.test
    */
    NntpClient c = new NntpClient(args[0]);
    c.setGroup(args[1]);
    NewsgroupInfo ni = c.getGroup(args[1]);
    int first = ni.firstArticle;
    int last = ni.lastArticle;
    for (int i = first; i <= last; i++) {
      String aLine;
      BufferedReader br = null; 
      InputStream anArticle = null;   
      try {
        anArticle = c.getArticle(i);
        br = new BufferedReader(new InputStreamReader(anArticle));
        System.out.println("-----------------\nArticle " + i);
        while ((aLine = br.readLine()) != null) {
          System.out.println(aLine);
          }
        }
      catch (NntpProtocolException e) {
        /* 
        ** probably a cancelled article, just skip it
        */
        }
      }
    }
  }
