Hi.Peter,
As one example.
When you use
----------------------------------------------------------------------------
InputStream inputStream = message.getInputStream(); //
ByteArrayDataSource inboundDataSource = new
ByteArrayDataSource(inputStream, message.getContentType());
Multipart inboundMultipart = new MimeMultipart(inboundDataSource);
----------------------------------------------------------------------------
Please switch the processing of each type by using
MimeMessage#isMimeType.
(In the offered source it is variable [message]. )
MimeMessage#isMimeType("multipart/*") == true
Convert into MimeMultipart.
MimeMessage#isMimeType("text/plain") == true
MimeMessage#isMimeType("text/html") == true
Need not convert into MimeMultipart.
Of course,
Jeremy Blythe have provided us information that [contentType.indexOf
( "multipart")] also Behave the same.
Thanks Jeremy Blythe.
Ikai.
Thank you variously for useful information as for processing
concerning the attached file to datastore ,etc.
Though it noticed now.
MimeMessage#isMimeType("multipart/*") == true
The return value of MimeMessage#getContent() seems to have changed
into Multipart. (SDK-1.2.8)
(The real thing environment has been updated recently. )
http://code.google.com/p/googleappengine/wiki/SdkForJavaReleaseNotes
When you use [message.getContent() ]
Such a method might be able to be used.
Object content = message.getContent();
if ( content instanceof Multipart){
MimeMultipart mmp = (MimeMultipart)content;
}
else{
//plain text/html part .etc
}
Though there might be an insufficient condition.
Please try.
thanks.
