java - How to convert byte[] to message with javax.mail library -


right have emails stored in database, , need able retrieve them , download attachments if have them. currently, stumped on way convert byte[] have stored email mailmessage or mimemessage. believe have gotten byte[] mimebody part not sure how parse through , pull out attachment.

final byte[] mailmessagestring = resultset.getbytes(mailmessageindex); file file = new file("c:\\users\\khurt\\downloads\\op.txt"); list<file> attachments = new arraylist<file>(); @suppresswarnings("deprecation") string mimetype = file.tourl().openconnection().getcontenttype(); mimebodypart att = new mimebodypart();  bytearraydatasource efe = new bytearraydatasource(mailmessagestring, mimetype);  datahandler dh = new datahandler(efe); att.setdatahandler(dh); att.setfilename(bds.getname()); multipart multipart = (multipart) att.getcontent(); multipart.addbodypart(att); (int = 0; < multipart.getcount(); i++)  {     bodypart bodypart = multipart.getbodypart(i);     if(!part.attachment.equalsignorecase(bodypart.getdisposition())         && !stringutils.isnotblank(bodypart.getfilename()))      {         inputstream = bodypart.getinputstream();         file f = new file("c:\\users\\khurt\\downloads\\"             + bodypart.getfilename());         fileoutputstream fos = new fileoutputstream(f);         byte[] buf = new byte[4096];         int bytesread;         while ((bytesread = is.read(buf)) != -1)          {             fos.write(buf, 0, bytesread);         }         fos.close();         attachments.add(f);     }     else     {         system.out.println("there nata");     } }

there no actual errors when gets - loop have not yet parsed email of files. possible parse through mimebodypart?

for reference emails have data email attachment starts empty line , then: (the email inst java, stack overflow wouldn't let me post without formatting it, though. emails don't have header info attachment).

use mimemessage constructor takes inputstream. access attachments in message in normal fashion. see msgshow.java sample program example code.
