Java Question

javax.mail unable to send attachment without setting content

i have a class which uses javax.mail.* to send multipart emails. when i try to send file with setting

content
is throws a
FileNotFoundException
. how ever, when is use
attachmentBodyPart.setContent(...)
it sends the email but replaces content of the file(kind of corrupts file other then text files). i also tried
attachmentBodyPart.attachFile(...)
i also throws same exception as before even after giving absolute path of the file. below is my class -

//all import statements
import javax.activation.DataHandler;
import javax.activation.DataSource;
import javax.activation.FileDataSource;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;

@Component
@Service
public class Notifier {

private static final Logger LOG = LoggerFactory.getLogger(Notifier.class);

@Override
public ResponseEntity<Object> sendEmail(InternetAddress[] to,
InternetAddress from,
InternetAddress[] cc,
String subject,
String body,
File attachment) {

Properties properties = System.getProperties();
//setting all the required properties
LOG.info("SMTP properties set!");

try
{
Session session = Session.getDefaultInstance(properties);
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(mail_from));
message.addRecipients(Message.RecipientType.TO, to);
message.addRecipients(Message.RecipientType.CC, cc);

if(subject.isEmpty() || subject.equalsIgnoreCase("")){
subject="No Subject";
}
message.setSubject(subject);

message.setHeader("X-Priority", "1");


Multipart multipart = new MimeMultipart();
//set attachment
if(attachment != null){
MimeBodyPart attachmentBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(attachment);
attachmentBodyPart.setDataHandler(new DataHandler(source));

attachmentBodyPart.setFileName(attachment.getName());
attachmentBodyPart.setContent(body, "text/plain;charset=utf-8");
//attachmentBodyPart.attachFile(attachment);
//create a mime body part for containing body
MimeBodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(body, "text/html;charset=utf-8");

multipart.addBodyPart(messageBodyPart);
multipart.addBodyPart(attachmentBodyPart);


LOG.info("Attachment and Body added to mail");
message.setContent(multipart);
}
Transport.send(message);
return new ResponseEntity<Object>(HttpStatus.ACCEPTED);
} catch (Exception e){e.printStackTrace();return null}

Answer

From your exception: it seems like the file you are sending to notifier is not available. Check with the calling method.
