Problems with JavaMail

[Mark Whitby]

Dear all,

I'm currently getting the following error when trying to test the JavaMail set 
up: javax.mail.MessagingException: Could not connect to SMTP host: localhost, 
port: 25; nested exception is: java.net.ConnectException: Connection refused: 
connect 

I'm using Tomcat 5.5 and have installed the jar files correctly as stated here: 
http://tomcat.apache.org/tomcat-5.5-doc/jndi-resources-howto.html

I'm guessing that there's a problem with my SMTP settings.  However, (apologise 
if I sound dense here) but the only mail client I have on my PC is Outlook 
Express.  Am I right in saying then that as well as JavaMail that I need an 
smtp server?  If so where can I get one?  If not where am I going wrong?

I have the following setups in my files:

context.xml:

<Context>

 <ResourceLink name="jdbc/TestDB"
  type="javax.sql.DataSource"  
     global="jdbc/TestDB"/>

<ResourceLink name="mail/Session" auth="Container"
            type="javax.mail.Session"
            mail.smtp.host="localhost"/>

</Context>

web.xml:

<resource-ref>
  <description>JavaMail Connection</description>
  <res-ref-name>mail/Session</res-ref-name>
  <res-type>javax.mail.Session</res-type>
  <res-auth>Container</res-auth>
</resource-ref>

Finally this is the code i'm testing:

Context initCtx = new InitialContext();
            Context envCtx = (Context) initCtx.lookup("java:comp/env");
            Session session = (Session) envCtx.lookup("mail/Session");
            
            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress("[EMAIL PROTECTED]"));
            InternetAddress to[] = new InternetAddress[1];
            to[0] = new InternetAddress("[EMAIL PROTECTED]");
            message.setRecipients(Message.RecipientType.TO, to);
            message.setSubject("Test email");
            message.setContent("Test email", "text/plain");
            Transport.send(message);

Can anyone tell me where I'm going wrong?

Many thanks
