Java mail - SMTP server question

[Daku]

Could some Java guru please help me ? I am running JRE 1.6_16 on a
Redhat EL 2.6.9_34 machine. I am using Eclipse Galileo for the actual
development. I have sendmail running on my machine.
I have in my constructor:
sysproperties = new Properties();
session = Session.getDefaultInstance(sysproperties);
transport = session.getTransport("smtp");
transport.connect("localhost.localdomain", "root", "rootpassword");

And I get an exception as:
TestMailer constructor provider exception
javax.mail.NoSuchProviderException: smtp

I have both mailapi-1.4.3.jar and javamail-1.4.3.zip in both my
compile-time and runtime CLASSPATHs.

May I know what I need to do ? Any hints, suggestions would be
immensely valuable. thanks in advance for your help.

As an alternative, the following code works:

Properties props = new Properties();
props.put("mail.smtp.host", smtpHost);
props.put("mail.from", from);

Session session = Session.getInstance(props);

Message msg = new MimeMessage(session);
// fill msg ...

Transport.send(msg);

You also need the jats containing the provides in the class path.
In this case smtp.jar - its in the 1.4.3 ZIP archive.

You also need the jats containing the provides in the class path. In
this case smtp.jar - its in the 1.4.3 ZIP archive.

Lets try that again, this time in English:

You also need to make sure that the jars containing the providers are in
the class path. In this case that means smtp.jar which is in the JavaMail
1.4.3 ZIP archive.

do you have the jar or the directory containing the jar on the
classpath. The second will not do. See
