MTOM DataHandler question

[Urmila & Sunil Bapat <su...@gmail.com>]

We have a scenario where a web service client calls a MTOM web service,
which in turn calls another MTOM web service to get the data, as shown
below.

Client ----> MTOM web service 1 ---> MTOM web service 2

Both MTOM web services return objects which contain DataHandler annotated
by @XmlMimeType("application/octet-stream").

Can the MTOM web service 1, simply return the same dataHandler object in
it's response to the client, that it got from MTOM web service 2?

Currently, MTOM web service 1 copies the contents of the data handler
returned from service 2, and creates a new data handler to return to the
client. Instead, can the same data handler object that is being returned by
service 2, be passed back to the client in service 1 response? Would there
be any problems?

Thanks
Sunil.

Hi,

I believe by default CXF use the stream way, that said, web service 1 should be able to reuse the data handler by default if you only have one attachment.

You may need elaborate your scenario a little bit, also, take a look at the related discussion here[1]
