Hi
 
I want to get the message from POP3 server.

The program which I used is


//It retrives the messages from POP3 server


import javax.mail.*;
import javax.mail.internet.*;

public class GetMessageFromPOP3 {
  public static void main (String args[])
      throws Exception {
    String host = args[0];
    String username = args[1];
    String password = args[2];

    // Get session
    Session session = Session.getInstance(
      System.getProperties(), null);

    // Get the store
    Store store = session.getStore("pop3");
    store.connect(host,110, username, password);

    // With out port no

    //store.connect(host,username, password);

    // Get folder
    Folder folder = store.getFolder("INBOX");
    folder.open(Folder.READ_ONLY);

    // Get directory
    Message message[] = folder.getMessages();
    for (int i=0, n=message.length; i<n; i++) {
       System.out.println(i + ": "
         + message[i].getFrom()[0]
         + "\t" + message[i].getSubject());
    }

    // Close connection
    folder.close(false);
    store.close();
  }
}

But it Gives Error:
C:\javamailcollections>java GetMessageFromPOP3 mail.bigthings.com irapy xyz
Exception in thread "main" javax.mail.NoSuchProviderException: No provider for p
op3
        at javax.mail.Session.getProvider(Session.java:249)
        at javax.mail.Session.getStore(Session.java:323)
        at javax.mail.Session.getStore(Session.java:303)
        at GetMessageFromPOP3.main(GetMessageFromPOP3.java, Compiled Code)

So what should i give in the place of host.
please give me more details about the POP3 Servers.

Download POP3.jar from Sun site and put it in your JRE\LIB\EXT folder.
