Re: [AXIS2] : Help required : getting a zip file using AXIS2 + AXIOM

[Thilina Gunarathne <cs...@gmail.com>]

Hi,
AFAIKS the problem lies in the code where you are trying to create the
byte[]. Also make sure that the zip file is created correctly in he
file system of your server.

I would recommend you to use the FileDataSource directly rather than
using a ByteArrayDataSource. With that you'll be able to create the
data source straight out from the file without creating byte[].

Also if you are planning to transfer large data, make sure to enable
MTOM in the server side.
