Hi Ikai,
I tried your example code, but I cannot attach an image on the email
that I send.
There is no conversion error either.
Here is snippets of the code, please help..
//Retrieving image:
URL url = new URL("http://stockcharts.com/c-sc/sc?s="; + ticker +
"&p=DAILY&b=5&g=0&i=0&r=3528");
//Sending mail
SendMail sendmail = new SendMail(customerEmail, url.openStream());
// send mail function
public SendMail(String recipient, InputStream imagestream) {
msg.setFrom( new InternetAddress("[email protected]", "dons
service"));
msg.addRecipient(Message.RecipientType.TO, new
InternetAddress
(recipient));
msg.setSubject("dons service daily charts");
Multipart multipart = new MimeMultipart();
MimeBodyPart htmlPart = new MimeBodyPart();
htmlPart.setContent(" url2: " , "text/html");
multipart.addBodyPart(htmlPart);
// append png image?
ByteArrayDataSource mimePartDataSource = new
ByteArrayDataSource
(imagestream, "image/png");
MimeBodyPart attachment = new MimeBodyPart();
attachment.setDataHandler(new
DataHandler(mimePartDataSource));
attachment.setFileName("ticker.png");
multipart.addBodyPart(attachment);
msg.setContent(multipart);
Transport.send(msg);
}
