javamail - Failing to parse this multi-part mime message body in Java -

-

i'm not writing mail application, don't have access headers , such. have block @ end of question. i've tried using javamail api parse this, using like

session s = session.getdefaultinstance(new properties()); inputstream = new bytearrayinputstream(<< string parse >>); mimemessage message = new mimemessage(s, is); multipart multipart = (multipart) message.getcontent();

but, tells me message.getcontent string, not multipart or mimemultipart. plus, don't need overhead of whole javamail api, need parse text it's parts. here's example:

 multi-part message in mime format.\n\n------=_nextpart_000_005d_01cc73d5.3ba43fb0\ncontent-type: text/plain;\n\tcharset="iso-8859-1"\ncontent-transfer-encoding: quoted-printable\n\nstuff:\n\n            please read stuff @ beginning of each week.  =\nfeel free discuss throughout week.\n\n\n--=20\n\nmrs. suzy m. smith\n555-555-5555\nsuzy@suzy.com\n------=_nextpart_000_005d_01cc73d5.3ba43fb0\ncontent-type: text/html;\n\tcharset="iso-8859-1"\ncontent-transfer-encoding: quoted-printable\n\n\n\n\n\n\n\n\n\nstuff:
\n           =20\nplease read stuff @ beginning of each =\nweek.  feel=20\nfree discuss throughout week.

there few things wrong text posted.

it not valid multi-part mime. check out wikipedia reference which, while non-normative, still correct.

the mime boundary not defined. wikipedia example: content-type: multipart/mixed; boundary="frontier" shows boundary "frontier". in example, "----=_nextpart_000_005d_01cc73d5.3ba43fb0" boundary, can determined scanning text (i.e. mime malformed). need instruct goofball passing mime content need know mime boundary value, not defined in message header. if entire body of message have enough because body of message starts mime-version: 1.0 followed content-type: multipart/mixed; boundary="frontier" frontier replaced value of boundary encoded mime.

if person sending body goofball (changed monkey because monkey judgemental - bad dwb), , not (more not know how to) send full body, can derive boundary scanning text line starts , ends "--" (i.e. --boundary--). note mentioned "line". terminal boundary "--boundary--\n".

finally, stuff posted has 2 parts. first part appears define substitutions take place in second part. if true, content-type: of first part should other "text/plain". perhaps "companyname/substitution-definition" or that. allow multiple (as in future enhancements) substitution formats.

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
