I made a message and encoded the attachment as base64...
(I think.) The beginning of the attachment comes out like this
when I send the message output to a file:

------=_Part_0_4872882.991375222570
Content-Type: application/octet-stream;
name=TestrptPublicActualProfiles20010417192350ActPrfl04112001.csv
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
filename=TestrptPublicActualProfiles20010417192350ActPrfl04112001.csv

MDguODQsMTA4LjQzLDEwOC4xNCwxMDcuOTgsMTA3Ljg4LDEwNy43NywxMDcuNzMsMTA3Ljc1LDEw

But when I try to get it decoded, using this code:

if (message.isMimeType("multipart/*")) {
Multipart multi = (Multipart)message.getContent();
BodyPart firstPart = multi.getBodyPart(0);
BodyPart secondPart = multi.getBodyPart(1);
InputStream fisDecoded = secondPart.getInputStream();
String[] sEncoding = secondPart.getHeader("Content-Transfer-Encoding");
if (sEncoding != null && sEncoding.length > 0) {
fisDecoded = MimeUtility.decode(fisDecoded, sEncoding[0]);
}
String disposition = secondPart.getDisposition();
System.out.println("Am I an attachment??? - disposition is: "+disposition);
printDecoded(fisDecoded);
}

I get nasty looking result (beginning of it):
Am I an attachment??? - disposition is: attachment
????m4????O??? ???????_? D?

Since it should look like this (after the out.print line):
9/25/2001 3:20:05 AM,9/25/2001,4

I am tearing my hair out. Any help would be TOTALLY
appreciated. Thank you.
