Hello Eddie,

Once again thanks for replying.
I tried removing the collection reader.. this thing now works the same 
way it worked in my CASE 2* .

The main thing I am concern with that in this case I need to send a 
loads of data over the net.. can't there be a way by which I could have 
rested my data on machine hosting the remote service.. and would have 
called my client without a collection reader.. or either providing only 
reference or some thing so that my network traffic could be lesser n 
processing be bit faster?? as i would practically never want to download 
the data first to client from my database and then  sending it to remote 
machine..

Secondly, when I define the the collection reader with the remote 
service and it even have data in the local system... what makes the 
processing go extremely slow?? indeed I was expecting it to be more 
faster... am I wrong somewhere??

Regards,
Lokesh
