Sounds like the encoding isn't set correctly somewhere along the way. How are you handling that?

[Badari Kandepi]

I wrote like this

message.setSubject(msg.getSubject());

// Setting Attachment & Body content
Multipart multipart = new MimeMultipart();
BodyPart part1 = new MimeBodyPart();
part1.setContent(new String(msg.getBody().toByteArray()), "text/html" );
multipart.addBodyPart(part1);
List<Attachment> attachments=msg.getAttachments();
for(Attachment attachObj:attachments)
{
BodyPart part = new MimeBodyPart();
DataSource dc = new ByteArrayDataSource(attachObj.getBody().toByteArray(), attachObj.getContentType());
part.setDataHandler(new DataHandler(dc));
part.setFileName(MimeUtility.encodeText(attachObj.getFileName()));
multipart.addBodyPart(part);
}
message.setContent(multipart);
Thread.currentThread().setContextClassLoader( MailClient.class.getClassLoader());
Transport.send(message);
result = "Sent message successfully....";

Using "new String()" without specifying the encoding is always suspect.

how can we do in this case?

You need to specify the charset. I believe the following will work:

part1.setContent(msg.getBody(), "text/html; charset=UTF-8");

Notice how I don't convert the body into a byte[] as that shouldn't be necessary. If it is however, you need to create a String with a specified encoding as well. In Java 7:

new String(msg.getBody().toByteArray(), StandardCharsets.UTF_8)

In Java 6 or before you need to use a String for the charset name and catch / rethrow the UnsupportedEncodingException, or create a Charset:

new String(msg.getBody().toByteArray(), Charset.forName("UTF-8")

it is not working for me . here msg.getBody() returns ByteArrayOutputStrem.please suggest me accordingly

Then use one of the other two code snippets I provided.
