Re: Sending mail with JavaMail

[David Tonhofer, m-plify S.A.]

Did you add the Java Activation Famework jar to your WEB-INF/lib?

Check this out:

Hi. I need to send an email using a servlet (Tomcat 4.1 / Debian 3.1), but when 
I send the form from the jsp page that call the servlet, i get this exception:

javax.servlet.ServletException: Servlet execution threw an exception

*root cause*

AltaCliente.doPost(AltaCliente.java:63) at 
javax.servlet.http.HttpServlet.service(HttpServlet.java:760) at 
javax.servlet.http.HttpServlet.service(HttpServlet.java:853)

This is the code of the servlet (which compiles with no problem):

---------------------------------
import java.io.*;
...
...

try {
                        Properties props = new Properties();
                        props.put("mail.smtp.host", "mail.***.***");
                        Session s = Session.getInstance(props);
                        MimeMessage message = new MimeMessage(s);

                        InternetAddress from = new InternetAddress("[EMAIL 
PROTECTED]");
                        message.setFrom(from);
                        InternetAddress to = new InternetAddress("[EMAIL 
PROTECTED]");
                        message.addRecipient(Message.RecipientType.TO, to);

                        message.setSubject("Prueba de JavaMail.");
                        message.setText("Hola desde JavaMail ( y Tomcat ). ");

                        Store store = s.getStore("pop3");
                        store.connect("mail.****.***", "[EMAIL PROTECTED]", 
"areyes");

                        Transport.send(message);
                        store.close();
 } catch ( MessagingException e ) {
                        out.println("<h1>MessagingException: " + e.getMessage() + 
"</h1>");
...
...
---------------------------------

The content of the /WEB-INF/web.xml is ok (only describe the servlet and others 
that I use), and the xml configuration for the context is:
---------------------------------
<Context path="/*****" docBase="/usr/share/tomcat4/server/webapps/******"
        debug="0" privileged="false">
 <Resource name="mail/Session" scope="Shareable" type="javax.mail.Session"/>
          <ResourceParams name="mail/Session">
            <parameter>
              <name>mail.smtp.host</name>
              <value>mail.****.****</value>
            </parameter>
          </ResourceParams>

</Context>
---------------------------------

Thanks in advance.
