Binary data is sent by value, not by reference in AXIS2-1.1.1

[donald yang <do...@googlemail.com>]

Hi,

I wrote one test web service (see[1] [2]) to return binary attachment.
However I found the binary data is returned by value, not by reference(see
[3]). I have enabled both MTOM and SwA in the server side by chaning the
values of enableMTOM and enableSwA to true the axis2.xml. Do I miss
something? Many thanks inadvance.

best regards
donald
