JavaMail set content to utf-8

[Kevin Valencia]

Hi all,
I'm using javamail to send email notification which contains chinese or japanese characters. Subject line correctly displays chinese characters, however, the email content is garbled. How will i be able to encode the characters in utf-8? I've tried using MimeBodyPart methods such as setContent and setText, but still doesn't work.

Appreciate your help on this.

Below is the code:

theContent = content.getContent();
            if ((attachments != null) || (attachments.size() != 0)) {
                Multipart     masterPart;
                MimeBodyPart  bodyPart;
                Content       crnt;
                
                masterPart = new MimeMultipart();
                bodyPart   = new MimeBodyPart();
                
                setMimePart(bodyPart, theContent);
                
                bodyPart.setContent(theContent, "UTF-8");
                masterPart.addBodyPart(bodyPart);
                
                for (Iterator it = attachments.iterator(); it.hasNext(); ) {                    
                    bodyPart = new MimeBodyPart();
                    setMimePart(bodyPart, (Content) it.next());
                    bodyPart.setDisposition(MimePart.ATTACHMENT);
                    masterPart.addBodyPart(bodyPart);
                }
                
                message.setContent(masterPart);
    

setMimePart method does this:

  private void setMimePart(MimePart part, Content content) 
    throws MalformedURLException, MessagingException {
        Properties props = content.getProperties();
        byte                data[] = content.getData();
        String     name  = content.getName();
            ByteArrayDataSource src;
            
        src = new ByteArrayDataSource(name, content.getMimeType(), data);
            part.setDataHandler(new DataHandler(src));
        
        for (Iterator it = props.entrySet().iterator(); it.hasNext(); ) {
            Map.Entry entry = (Map.Entry) it.next();
                        
            part.setHeader((String) entry.getKey(), (String) entry.getValue());
        }
        
        if (name != null) {
            part.setFileName(name);
        }
       
    }
  

Result of email content is like this:

please use this code :
you can use any character in subject and body.

MimeMessage message = new MimeMessage( session );

message.setFrom( new InternetAddress( from ) );
message.addRecipient( Message.RecipientType.TO, new InternetAddress( toStringAddress ) );
message.addRecipient( Message.RecipientType.BCC, new InternetAddress( bccStringAddress ) );

// Setting the Subject and Content Type
message.setSubject( subject, "utf-8" ); // <----

// Create a message part to represent the body text
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent( messageContent, "text/html; charset=utf-8" ); // <----

// use a MimeMultipart as we need to handle the file attachments
Multipart multipart = new MimeMultipart();

// add the message body to the mime message
multipart.addBodyPart( messageBodyPart );

// Put all message parts in the message
message.setContent( multipart );

Transport.send( message );

Seems to me that you are assuming that "theContent" (which I don't see a declaration for) isn't already garbled.

The following line did not work

message.setSubject( subject, "utf-8" );

it must be

message.setSubject(subject);

how to encode the subject of the email?

thanks a lot in advance

I faced same problem but below code resolve

MimeBodyPart bodypart = new MimeBodyPart();
if(emailType.equalsIgnoreCase("text/html")){ //$NON-NLS-1$
bodypart.setHeader("Content-Type","text/plain; charset=\"utf-8\"");
bodypart.setContent( emailBody, "text/plain; charset=utf-8" );
bodypart.setHeader("Content-Transfer-Encoding", "quoted-printable");
