Hallo all
I am running a Java servlet on a Linux box. All the servlet needs to do
is send an HTML email with an image embedded to a given address. But I
am getting the following error while sending the email:

I would like to know if anybody has any idea why this is happening. I am
using the standard java mail api and here is the code I use to send the
email.
// create some properties and get the default Session
javax.mail.Session session =
javax.mail.Session.getDefaultInstance(emailProps, null);
session.setDebug(true);
// create a message
javax.mail.Message msg = new MimeMessage(session);
// set the from and to address
msg.setFrom(new InternetAddress(msgFromAddr, msgFromName));
msg.setRecipient(javax.mail.Message.RecipientType.TO, new
InternetAddress(msgTo));
// Setting the Subject and Content Type
msg.setSubject(subject);
//msg.setContent(body, "text/html");
// Create your new message part
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(body, "text/html");
// Create a related multi-part to combine the parts
MimeMultipart multipart = new MimeMultipart("related");
multipart.addBodyPart(messageBodyPart);
// Create part for the image
messageBodyPart = new MimeBodyPart();
// Fetch the image and associate to part
DataSource fds = new
FileDataSource("/usr/share/tomcat5/image.jpg ");
messageBodyPart.setDataHandler(new DataHandler(fds));
messageBodyPart.setHeader("Content-ID","<[EMAIL PROTECTED]>");
// Add part to multi-part
multipart.addBodyPart(messageBodyPart);
// Create 2nd part for the image
messageBodyPart = new MimeBodyPart();
// Fetch the image and associate to part
DataSource fds2 = new
FileDataSource("/usr/share/tomcat5/image.jpg");
messageBodyPart.setDataHandler(new DataHandler(fds2));
messageBodyPart.setHeader("Content-ID","<youyouyou>");
// Add part to multi-part
multipart.addBodyPart(messageBodyPart);
// Associate multi-part with message
msg.setContent(multipart);
// Send message
Transport.send(msg);
Any help would be appreciated. I am all out of ideas.
Thanks
Johan
