It is very likely *not* field 43 that is the problem, but the
preceeding field leading to the data that the Packager *thinks* is
field 43.

What are you using on the server side?
The Channel and the Packager must match precisly at both ends.

Add a Logger to your Packager and Channel;- at both server and client
and check the output for what data is going into which fields.
There was a very recent discussion on this very list, I will let you
look for it.
There will be a difference between each ends output (on the response
flow) and where the difference starts will be where your Packager (or
Channel) is different.

I would first check the Channel and Packager are the same, but also
that you are not intrducing any headers to the messages?

Anil, please refrain from sending emails to me off list.
I won't respond to them unless I have initiated the discussion or there
is a large payment attached to the envelope!
