Forgotten password code

Question

I want to enable users the facility of having their password mailed to them based on user name. Fairly standard stuff.
Here's how I see it.
Link from 'Forgotten password' opens jsp/html page, user enters user name in text field then clicks on submit.
The submit button then runs a java bean which interrogates a mysql database, extracts the password and mail address based on user name then mails the user.
If success, an alert box pops up saying 'password mailed' otherwise alert box pops up with failure.
I can set everything up as far as extracting the relevant information, the bit I'm stuck on is how to send a mail from within a java bean
Any help appreciated
Thanks

Answer 1

well, there are a lot of examples you can find on the net.
i can't find right now the code i use for this stuff. but i found a base for the method i have, you have to check it and fix it, this is an early "check_how_it_works" version, the method signature has too many variables you don't actually need and you can change it as you want.
import javax.mail.*;
import javax.mail.internet.*;
public void sendEmail(int to_number,String [] emailto, String emailfrom, String smtphost, String emailmultipart, String msgSubject, String msgText)
     boolean debug = false; // change to get more information
     String msgText2 = "multipart message";
     boolean sendmultipart = Boolean.valueOf(emailmultipart).booleanValue();
     // set the host
     Properties props = new Properties();
     props.put("mail.smtp.host", smtphost);
     // create some properties and get the default Session
     Session session = Session.getDefaultInstance(props, null);
     session.setDebug(debug);
     try
     // create a message
     Message msg = new MimeMessage(session);
     // set the from
     InternetAddress from = new InternetAddress(emailfrom);
     msg.setFrom(from);
     InternetAddress[] address = new InternetAddress[to_number];
     for(int i=0;i<to_number;i++)
          address=new InternetAddress(emailto[i]);
     msg.setRecipients(Message.RecipientType.TO, address);
     msg.setSubject(msgSubject);
     if(!sendmultipart)
     // send a plain text message
     msg.setContent(msgText, "text/plain");
     else
     // send a multipart message// create and fill the first message part
     MimeBodyPart mbp1 = new MimeBodyPart();
     mbp1.setContent(msgText, "text/html");
     // create and fill the second message part
     //MimeBodyPart mbp2 = new MimeBodyPart();
     //mbp2.setContent(msgText2, "text/html");
     // create the Multipart and its parts to it
     Multipart mp = new MimeMultipart();
     mp.addBodyPart(mbp1);
     //mp.addBodyPart(mbp2);
     // add the Multipart to the message
     msg.setContent(mp);
     Transport.send(msg);
     catch(MessagingException mex)
     mex.printStackTrace();
