Hi,
i'm new to jguru. What a nice site!
First i hope my bad english won't be a big problem...



I'm trying to download jpg pictures from newsgroups with javamail.

I use the Knife provider. All is ok when the pictures are attachments and the message type is "multipart/*". But when the picture is encoded in a "text/plain" message i have some problems saving it in a file.


I've read a lot of articles on javamail and a lot of questions in this forum but i didn't find what i'm looking for!
My problem is to know how to decode the rigth part of the message ( the image part). I've try with MimeUtility.decode(in ,"base64" ) and with MimeUtility.decode(in ,"uuencode" ). The resulting file using "uuencode" decoding is a 0 K file. The resulting file with "base64" decoding has a realistic size but is not seen as a image file...


Any help will be really appreciated!

Thanks a lot...



Here's my code:


--------------------------

			

			for (int i = 0, n = message.length; i
			< n ; i++) {
			

			if (message[i].isMimeType("text/plain")) {
			

			

			int pos1 = -1 ,pos2 = -1 ,posFin = -1 ;
			

			String sautLigne = "
			

			" ;
			

			String contenuString = (String) message[i].getContent() ;
			

			

			if((pos1 = contenuString.indexOf(sautLigne + "begin ")) == -1)
			

			continue ;
			

			

			pos2 = contenuString.indexOf(sautLigne,pos1 + 1) ;
			

			

			if(contenuString.substring(pos1,pos2).indexOf(".jpg") == -1)
			

			continue ;
			

			

			if((posFin = contenuString.indexOf("`" + sautLigne + "end",pos2)) == -1)
			

			continue ;
			

			

			contenuString = contenuString.substring(pos2 + 1,posFin) ;
			

			

			ByteArrayInputStream in= new ByteArrayInputStream( contenuString.getBytes() ) ;
			

			

			InputStream StringDecoded = MimeUtility.decode(in ,"base64" ) ; //"uuencode");
			

			

			File fichier = new File("D:\web\test" + i + ".jpg");
			

			fichier.createNewFile();
			

			

			FileOutputStream fichierOut = new FileOutputStream(fichier) ;
			

			

			int size= StringDecoded.available() ;
			

			byte[] buff = new byte[size] ;
			

			

			while(StringDecoded.read(buff) != -1)
			

			fichierOut.write(buff);
			

			

			fichierOut.flush() ;
			

			fichierOut.close() ;
			

			}
			

			}
