[bhaniel]

import java.util.Properties;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMessage.RecipientType;


public

class SendMail
{

	private static String HOST = "smtp.gmail.com";
	private static String USER = "java.web.programming";//"yourmail.com";
	private static String PASSWORD = "javaprogramming";
	private static String PORT = "587";
	private static String FROM = "mail.com";
	private static String TO;
	private static String STARTTLS = "true";
	private static String AUTH = "true";
	private static String DEBUG = "true";
	private static String SOCKET_FACTORY = "javax.net.ssl.SSLSocketFactory";
	private static String SUBJECT = "Testing JavaMail API";
	private static String TEXT = "This is a test message from my java application. Just ignore it";
	
	public synchronized void send(String to)
	{
	
		TO = to;
		//Use Properties object to set environment properties
		Properties props = new Properties();
		props.put("mail.smtp.host", HOST);
		props.put("mail.smtp.port", PORT);
		props.put("mail.smtp.user", USER);
		props.put("mail.smtp.auth", AUTH);
		props.put("mail.smtp.starttls.enable", STARTTLS);
		props.put("mail.smtp.debug", DEBUG);
		props.put("mail.smtp.socketFactory.port", PORT);
		props.put("mail.smtp.socketFactory.class", SOCKET_FACTORY);
		props.put("mail.smtp.socketFactory.fallback", "false");
		
		try
		{
		
			//Obtain the default mail session
			Session session = Session.getDefaultInstance(props, null);
			session.setDebug(true);
			//Construct the mail message
			MimeMessage message = new MimeMessage(session);
			message.setText(TEXT);
			message.setSubject(SUBJECT);
			message.setFrom(new InternetAddress(FROM));
			message.addRecipient(RecipientType.TO, new InternetAddress(TO));
			message.saveChanges();
			
			//Use Transport to deliver the message
			Transport transport = session.getTransport("smtp");
			transport.connect(HOST, USER, PASSWORD);
			transport.sendMessage(message, message.getAllRecipients());
			
			transport.close();
			
		} catch (Exception e){
		
			e.printStackTrace();
		
		}

	}
	
	public static void main(String[] args){
		(new SendMail()).send("litvak.marina@gmail.com");
	}

Could not connect to SMTP host: smtp.gmail.com, port: 587;

Why do you think the server is listening on that port? And that it is willing to connect with your code?

[bhaniel]

because it's the gmail confrmation for the host and the port.
this code is working fine in my friend laptop but in a diffrent nwetwork i dont know why.
maybe there is somthing that i need to install?

and by the way i dont have any firewall.

this code is working fine in my friend laptop but in a diffrent nwetwork i dont know why.

Your ISP may be blocking SMTP traffic.
Can you send mails through that server using a desktop email client, like
Outlook, Thunderbird etc?
