Sending Email (Java Program)
I am creating my own program that will send email out. I have a GUI that calls the frame emailFrame(); which has the Email code in it.
My problem is that I think my code is correct, but I have no mail server to connect to. Every SMTP server I try to connect to requires authentication. I don't know how to authenticate using my program. Is there anything I can add or alter in my code to get this to work, or possibly a free smtp server that doesn't require the AUTH command?
Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.net.*;
import java.io.*;
import javax.mail.*;
import javax.mail.internet.*;
public class emailFrame extends JFrame implements ActionListener
{
// Keep a reference to the applet parent.
JPanel n,s,outer;
JLabel lblEaddress, lblCC, lblSubject, lblFrom;
JTextField txtEaddress, txtCC, txtSubject, txtFrom;
JTextArea txtBody;
JButton btnEsend;
String Eaddress, CC, Subject, Body, From,smtpServer;
public emailFrame()
{
Container c = getContentPane();
setTitle("Compose Email");
lblFrom = new JLabel("From?");
txtFrom = new JTextField(20);
lblEaddress = new JLabel("Address:");
txtEaddress = new JTextField(20);
lblCC = new JLabel("CC:");
txtCC = new JTextField(20);
lblSubject = new JLabel("Subject:");
txtSubject = new JTextField(20);
txtBody = new JTextArea("",5,50);
btnEsend = new JButton("Send");
btnEsend.addActionListener(this);
n = new JPanel();
n.setLayout(new GridLayout(4,2));
n.add(lblEaddress);
n.add(txtEaddress);
n.add(lblCC);
n.add(txtCC);
n.add(lblSubject);
n.add(txtSubject);
s = new JPanel();
s.setLayout(new GridLayout(2,1));
s.add(txtBody);
s.add(btnEsend);
outer = new JPanel(new BorderLayout());
outer.add(n, BorderLayout.NORTH);
outer.add(s, BorderLayout.CENTER);
c.add(outer);
}
public void actionPerformed(ActionEvent evt)
{
if(evt.getSource()==btnEsend)
{
From = (txtEaddress.getText());
Eaddress = (txtEaddress.getText());
CC = (txtCC.getText());
Subject = (txtSubject.getText());
Body = (txtBody.getText());
sendMail(From, Eaddress, CC, Subject, Body);
}
}
public void sendMail(String From, String Eaddress, String CC, String Subject, String Body)
{
try {
Socket s = new Socket("smtp.server.com", 25);
BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream()));
BufferedWriter out = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
//Send username to mail server
sendln(in, out, "HELO [email protected]");
sendln(in, out, "MAIL FROM: <[email protected]>");
sendln(in, out, "RCPT TO: <" + Eaddress + ">");
sendln(in, out, "RCPT TO: <" + CC + ">");
sendln(in, out, "DATA");
sendln(out, Body);
sendln(in, out, ".");
sendln(in, out, "QUIT");
s.close();
}
catch(Exception e)
{
e.printStackTrace();
}
}
public void sendln(BufferedReader in, BufferedWriter out, String s) {
try {
out.write(s + "\r\n");
out.flush();
// System.out.println(s);
s = in.readLine();
// System.out.println(s);
}
catch(Exception e)
{
e.printStackTrace();
}
}
public void sendln(BufferedWriter out, String s) {
try {
out.write(s + "\r\n");
out.flush();
System.out.println(s);
}
catch (Exception e) {
e.printStackTrace();
}
}
Let me know if you need to see my main frame where emailFrame() gets called.
