---------------------------------
Hi Freeman Yue Fang,
It's not exactly the scenario you describe because I am not directly packaging
the attachment stream into a message passed to the AMQ queue.
Indeed, I get the attachments map in cxf server side (The issue occurs here),
next I turn it into a serializable map (to respect the JMS TextMessage format),
next I package the serialized map in a JMS message.
I can understand that you don't want to cache the inpustream of the request,
but, in my opinion, the methods provided by your API should work.
* AttachmentUtils.populateFormMap
* AttachmentUtils.getMultipartBody
* (MultipartBody)mc.get(MultipartBody.INBOUND_MESSAGE_ATTACHMENTS
However, I found a workaround by following your advise and with the help of
this page :
https://stackoverflow.com/Questions/10210645/http-servlet-request-lose-params-from-post-body-after-read-it-once
I created a filter and a request wrapper in order to read the inputsream
multiple times.
Next I created a ContainerRequestFilter to store the attachments map into the
message in order to get this map later in my code.
It works but It was a little bit tricky to parse the body and transform it into
attachments map :p (And I still have encoding issues)
Therefore, I will appreciate that this functionality is provided by CXF

> Priority: Blocker
>
> I need to get the attachments map, but the first attachment is still empty.
> I think the issue comes from the method
> org.apache.cxf.jaxrs.ext.MessageContextImpl.createAttachments line 292
> The first attachment is loaded with the following method
> "inMessage.getContent(InputStream.class)"
> but the InputStream is not buffered and so I think when i want to read this
> value later in my code, the stream is closed and I get an empty string.
