Based on 238 examples
public class MimeBodyPart extends BodyPart implements MimePart
This class represents a MIME body part. It implements the
BodyPart
abstract class and the MimePart
interface. MimeBodyParts are contained in MimeMultipart
objects.
MimeBodyPart uses the InternetHeaders
class to parse
and store the headers of that body part.
RFC 822 header fields must contain only
US-ASCII characters. MIME allows non ASCII characters to be present
in certain portions of certain headers, by encoding those characters.
RFC 2047 specifies the rules for doing this. The MimeUtility
class provided in this package can be used to to achieve this.
Callers of the setHeader
, addHeader
, and
addHeaderLine
methods are responsible for enforcing
the MIME requirements for the specified headers. In addition, these
header fields must be folded (wrapped) before being sent if they
exceed the line length limitation for the transport (1000 bytes for
SMTP). Received headers may have been folded. The application is
responsible for folding and unfolding headers as appropriate.

public MimeBodyPart(InputStream is) throws MessagingException
Note that the "boundary" string that delimits body parts must not be included in the input stream. The intention is that the MimeMultipart parser will extract each body part's bytes from a multipart stream and feed them into this constructor, without the delimiter strings.

public Object getContent() throws IOException, MessagingException
This implementation obtains the content from the DataHandler. That is, it invokes getDataHandler().getContent(); If the content is a Multipart or Message object and was created by parsing a stream, the object is cached and returned in subsequent calls so that modifications to the content will not be lost.

If the Content-Description field is encoded as per RFC 2047, it is decoded and converted into Unicode. If the decoding or conversion fails, the raw data is returned as is.
This implementation uses getHeader(name)
to obtain the requisite header field.

If the Content-Disposition field is unavailable, null is returned.
This implementation uses getHeader(name)
to obtain the requisite header field.

or its value is absent.
This implementation uses getHeader(name)
to obtain the requisite header field.
MessagingException
public String getFileName() throws MessagingException
Returns the value of the "filename" parameter from the
"Content-Disposition" header field of this body part. If its
not available, returns the value of the "name" parameter from
the "Content-Type" header field of this body part.
Returns null
if both are absent.
If the mail.mime.encodefilename
System property
is set to true, the {@link MimeUtility#decodeText
MimeUtility.decodeText} method will be used to decode the
filename. While such encoding is not supported by the MIME
spec, many mailers use this technique to support non-ASCII
characters in filenames. The default value of this property
is false.

,
a DataContentHandler for "application/x-foobar" should be installed.
