Hi All,
I've got a problem sending email via smtp using tomcat3.2.1 and jdk1.2.2.
The code works fine with Javawebserver2.0 and iPlanet webserver. But when I migrate it to tomcat, I got the following error message.
javax.mail.NoSuchProviderException: No provider for smtp.

can anybody give a hand on how to overcome such a problem? The jsp code is as following:

<%@ page import="java.sql.*, database.*, java.io.*, java.net.*, java.util.*, javax.mail.*, javax.mail.internet.*, javax.activation.*" %>

<%
/* some irrelevant codes here ommitted */

// we're using SMTP
/* assume the message msgText, from and to address already constructed
*/

String mailhost = "smtp.convoke.com";
String mailer = "msgsend";
boolean debug = false;
Properties props = new Properties();
props.put("mail.smtp.host",mailhost);

//get an session object
javax.mail.Session ss = Session.getDefaultInstance(props, null);
ss.setDebug(debug);

Message msg = new MimeMessage(ss);
msg.setFrom(new InternetAddress(from));
msg.setSubject(subject);
msg.setSentDate(new java.util.Date());

msg.setContent(msgText,"text/html");
msg.setText(msgText);
msg.saveChanges();

//recipients
InternetAddress[] recipients={new InternetAddress("zl3@hotmail.com")};

Transport t=ss.getTransport("smtp");
t.connect();
t.sendMessage(msg, recipients);
t.close();
