Does MTOM keep filename?

[Boxiong Ding <bo...@yahoo.com>]

I have a service that uses MTOM to send a image file. As a client I can get the data, but the file name is lost. I have tried to set it in ByteArrayDataSource.setName() and create a DataHandler using it on server side. But still, the client always get null from DataSource.getName() and when I use tcpmon to look at the traffic, I couldn't find the file name any where.

Is this how it works? And how can I preserver the file name?

Thanks,
Boxiong

Yea, in general, the name is considered a system dependent property  
and the client should get to chose what makes sense for them .  If the  
name is important, it should be transferred in the actual data.

I suppose we COULD throw the name into a mime header on the part, but  
we'd be the only toolkit to really do that or understand that.   Thus,  
it wouldn't exactly be portable.

>From a protocol standpoint, the MTOM wire protocol does not carry a file
name. The fact that the data handler class carries a pathname is a bit of a
red herring. If you want to carry a file name, use another element.

It seems to me that there is some hypothetical possibility that the XOP/Mime
part could carry a file name, but I don't see a viable way to carry that
around. Similiarly, XOP could use a URL other than cid: to refer to some
other kind of resource, but I don't know if that would count as MTOM.

Pardon the non-answer, but for my MTOM example
(http://www.jroller.com/gmazza/date/20071102), in step #11, I let the client
set the name.  Wouldn't it seem more natural to let the client decide what
it wants the file it obtains to be called?

As an alternative, perhaps best to send a separate String element for the
filename in the SOAP response, then your client can name the file based on
that name.  Perhaps even a more portable solution.
