Using James Server in Eclipse With JavaMail

Question

Would anyone be able to tell me how I can go about using James server as my server with Java in Eclipse?

I'm trying to test the two classes posted below but i get the following error: Exception in thread "main" javax.mail.AuthenticationFailedException: Authentication failed.

public class JamesConfigTest
{
public static void main(String[] args)
throws Exception
{
// CREATE CLIENT INSTANCES
MailClient redClient = new MailClient("red", "localhost");
MailClient greenClient = new MailClient("green", "localhost");
MailClient blueClient = new MailClient("blue", "localhost");

// CLEAR EVERYBODY'S INBOX
redClient.checkInbox(MailClient.CLEAR_MESSAGES);
greenClient.checkInbox(MailClient.CLEAR_MESSAGES);
blueClient.checkInbox(MailClient.CLEAR_MESSAGES);
Thread.sleep(500); // Let the server catch up

// SEND A COUPLE OF MESSAGES TO BLUE (FROM RED AND GREEN)
redClient.sendMessage(
  "blue@localhost",
  "Testing blue from red",
  "This is a test message");
greenClient.sendMessage(
  "blue@localhost",
  "Testing blue from green",
  "This is a test message");
Thread.sleep(500); // Let the server catch up

// LIST MESSAGES FOR BLUE (EXPECT MESSAGES FROM RED AND GREEN)
blueClient.checkInbox(MailClient.SHOW_AND_CLEAR);
}
}
