ok, well bel helped me out and pointed me to javamail. i can't make this work without an exception. here is my function:

public static void sendEmail(String to, String from, String subject, String body){
  try{
    Properties props = System.getProperties();

    props.put("mail.smtp.host", "mail.mycompany.com");
    props.put("mail.smtp.port", "25");
    props.put("mail.transport.protocol","smtp");

    Session session = Session.getInstance(props, null);
    Message msg = new MimeMessage(session);

    msg.setFrom(new InternetAddress(from));
    msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to, false));

    msg.setSubject(subject);
    msg.setText(body);

    msg.setSentDate(new Date());

    Transport.send(msg);
  }catch(Exception e){
    System.out.println("sendEmail()"+ e.toString());
  }
}

and here's my exception:

javax.servlet.ServletException: javax/activation/DataSource
