Hi all,
Given an Attachments object, Is there a clean and simple way to
distinguish the SOAP part from non SOAP parts?
To better understand the question, some background:
* When the Attachments instance is built from an incoming message
using one of the constructors taking an InputStream as argument, it
will contain DataHandler objects both for the SOAP (root) part and non
SOAP parts (the attachments). In this case,
Attachments#getSOAPPartContentID can be used to identify the SOAP part.
* When the Attachments instance is built programmatically for an
outgoing message, it will contain only the non SOAP parts (see
MIMEOutputUtils.writeSOAPWithAttachmentsMessage). However there seems
to be no (clean) way to distinguish this situation from the first one
(because Attachments doesn't have a method giving access to the
noStreams attribute). Also in this case, a call to
Attachments#getSOAPPartContentID will result in a NullPointerException
(because the contentType attribute is null).
Regards,
Andreas
