> ---------------------------
> Hi all
> I sincerely apologise for the delay, I have had other priorities and had to
> put this aside till now, after futher debugging I have come across the cause
> of the java.io.IOException: Bad file descriptor error.
> In the file /org/mime4j/message/Header.java the following code is found
> public void writeTo(OutputStream out) throws IOException {
> String charString = ((ContentTypeField)
> getField(Field.CONTENT_TYPE)).getCharset();
> BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(out,
> CharsetUtil.getCharset(charString)),8192);
> writer.write(toString()+ "\r\n");
> writer.flush();
> writer.close();
> }
> as you can see the output stream is closed here.
> This is cause of the IOException as the stream is used later again for
> writing.
> I tried commenting the writer.close(); call and it worked fine, however I
> dont know what the implications of this may be.
> The case I am facing is a multipart message which calls the writeTo method
> below
> public void writeTo(OutputStream out) throws IOException {
> getHeader().writeTo(out);
> Body body = getBody();
> if (body instanceof Multipart) {
> Multipart mp = (Multipart) body;
> mp.writeTo(out);
> } else {
> body.writeTo(out);
> }
> }
> when getHeader().writeTo(out); is called the stream is closed and when
> mp.writeTo(out); is called the exception is throw as the stream is
> closed.Regards
