Hello all,
I have tried to send mail using this code...
* This program sends e-mail using a mailto: URL
public class SendMail {
public static void main(String[] args) {
try {
// If the user specified a mailhost, tell the system about it.
if (args.length >= 1)
System.getProperties().put("", args[0]);
// A Reader stream to read from the console
BufferedReader in =
new BufferedReader(new InputStreamReader(;
// Ask the user for the from, to, and subject lines
System.out.print("From: ");
String from = in.readLine();
System.out.print("To: ");
String to = in.readLine();
System.out.print("Subject: ");
String subject = in.readLine();
// Establish a network connection for sending mail
URL u = new URL("mailto:" + to); // Create a mailto: URL
URLConnection c = u.openConnection(); // Create its URLConnection
c.setDoInput(false); // Specify no input from it
c.setDoOutput(true); // Specify we'll do output
System.out.println("Connecting..."); // Tell the user
System.out.flush(); // Tell them right now
c.connect(); // Connect to mail host
PrintWriter out = // Get output stream to host
new PrintWriter(new OutputStreamWriter(c.getOutputStream()));
// Write out mail headers. Don't let users fake the From address
out.print("From: \"" + from + "\" <" +
System.getProperty("") + "@" +
InetAddress.getLocalHost().getHostName() + ">\n");
out.print("To: " + to + "\n");
out.print("Subject: " + subject + "\n");
out.print("\n"); // blank line to end the list of headers
// Now ask the user to enter the body of the message
System.out.println("Enter the message. " +
"End with a '.' on a line by itself.");
// Read message line by line and send it out.
String line;
for(; {
line = in.readLine();
if ((line == null) || line.equals(".")) break;
out.print(line + "\n");
// Close (and flush) the stream to terminate the message
// Tell the user it was successfully sent.
System.out.println("Message sent.");
catch (Exception e) { // Handle any exceptions, print error message.
System.err.println("Usage: java SendMail [<mailhost>]");
The program hangs on 'c.connect()' trying to find a connection i guess.
I submitted my mail host and my own e-mail address but it just hangs and somtimes it states that the connection is not found what am i doing wrong.

confused person.

Hi John,
At first glance, this question is not related to the webservices forum.
Maybe you should better post it elsewhere (java forum for instance)

John, J-L is correct. This post should be moved to some other forum (I already asked the moderator to do just that).
In the meanwhile, you might want to Google for "JavaMail tutorial" or something like that.
