Folks
getDataHandler method of org.apache.axiom.attachments.Attachments returns
NULL when it can't find the content part it is looking based on the content
id. Shouldn't it return something else? I mean, if you return null its very
obvious that you get null pointer exception from this call is originiated,
in my case, org.apache.axiom.attachments.Attachments.getSOAPPartContentType.
I am not really sure why would you want to return null. Instead, You can
handle the null case and throw an exception stating, required content based
on content id not found in message etc.
I have copied my response MIME encoded message and please let me know if its
missing any MIME parts. My response schema has NO element of type
base64Binary, howerver, the response is MIME encoded.
Checks whether the MIME part is already parsed by checking the attachments
HashMap. If it is not parsed yet then call the getNextPart() till the
required part is found.
Parameters: blobContentID (without the surrounding angle brackets and
"cid:" prefix) Returns: The DataHandler of the mime part referred by the
Content-Id or *null* if the mime part referred by the content-id does not
exist
