Sending attachment from servlet or jsp

Question

Dear Friends,
I downloaded javamail api and I have seen the sendfile.java, which is used to send attachments. it is working fine. I can able to run that program from command prompt like this :=
c:>java sendfile [email protected] [email protected] mail.smtp.net c:/hello.java true
It is working fine from console (command prompt)
How can i execute that file on browser (i have to run as a servlet file or from jsp file).
please help me how can i pass the emailids, file etc., if i want to use this program as servlet file or as jsp program.
If anyone having idea, please share ur ideas.
your kind cooperation would be greatly appreciated.
Thanks in advance.
Looking forward to hearing from you.
Yours
Rajesh

* sendfile will create a multipart message with the second
* block of the message being the given file.<p>
* This demonstrates how to use the FileDataSource to send
* a file via mail.<p>
* usage: <code>java sendfile <i>to from smtp file true|false</i></code>
* where <i>to</i> and <i>from</i> are the destination and
* origin email addresses, respectively, and <i>smtp</i>
* is the hostname of the machine that has smtp server
* running. <i>file</i> is the file to send. The next parameter
* either turns on or turns off debugging during sending.

Hi,
your sendmail.jsp would look like that:
<%@ page import="java.util.*,java.io.*,javax.mail.*,javax.mail.internet.*,javax.activation.*" %>
<%
String to = request.getParameterValues("to")[0];
String from = request.getParameterValues("from")[0];
String host = request.getParameterValues("host")[0];
String filename = request.getParameterValues("filename")[0];
String msgText1 = "Sending a file.\n";
String subject = "Sending a file";
// create some properties and get the default Session
Properties props = System.getProperties();
props.put("mail.smtp.host", host);
Session session = Session.getDefaultInstance(props, null);
session.setDebug(debug);
try {
// create a message
MimeMessage msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(from));
InternetAddress[] address = {new InternetAddress(to)};
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject(subject);
// create and fill the first message part
MimeBodyPart mbp1 = new MimeBodyPart();
mbp1.setText(msgText1);
// create the second message part
MimeBodyPart mbp2 = new MimeBodyPart();
// attach the file to the message
FileDataSource fds = new FileDataSource(filename);
mbp2.setDataHandler(new DataHandler(fds));
mbp2.setFileName(fds.getName());
// 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);
// set the Date: header
msg.setSentDate(new Date());
// send the message
Transport.send(msg);
} catch (MessagingException mex) {
mex.printStackTrace();
Exception ex = null;
if ((ex = mex.getNextException()) != null) {
ex.printStackTrace();
%>
which you can call as: sendmail.jsp?to=...&from=...&host=...&filename=...
so you may need to create a HTML file containing the necessary form.
