iwcallback not working after upgrade 5.5.2

fuzzy

we were using tst 4.5.1 and opendeploy 4.5.1 on unix 7
we have upgraded our servers to tst 5.5 product suite (tst 5.5.2 and OD
5.5.1 and all patch and sp available)

we have a few workflows that when invoked on the tst server they start a
process on a different server (OD server) and when the process is finished
on the OD server a call is made to iwcallback -s tstserverIP ...
so that the workflow would transition to the next stage of the workflow.
the iwcallback is a copy of the iwcallback from the teamsite server
/app/iw-home/bin directory
having updated the scripts and the iwcallback from the tst5.5.2 version on
the OD server I get the following error message:
/iwcallback -s 170.20.1.29 1278 0 "finish waiting"
ERROR: TeamSite's install directory (/usr/iw-home) does not exist, please
make sure TeamSite is installed correctly
TeamSite I18N initialization failure.
To run TeamSite I18N version, please make sure $iwhome/lib/locale/*.nls
exist.
Make sure the locale you are running under is supported by TeamSite.
with teamsite 4.5.1 I did not have this problem
I also use the iwsettaskcomments and iwjobvariable on the remote server
and get a similar message
question:

why am I not able to use the iwcallback funtionaliyt from a different
server (a none teamsite server) was able in tst 4.5.1? since iwcallback
has a parameter for the teamsite server

is there a way arround this problem (by copying more files from the
teamsite server to the remote server)?

fuzzy

it seams like this functionality has been taken out or is a bug that they have to fix. To get arround the problem I have written a java client server program that would run the teamsite command locally on the teamsite server and would send back the output to the calling client. Therefore the calling client will initiate the call and then would get the information back. My clients are my opendeploy servers
so if on the client side I need to get a workflow variable or ask the workflow to go to the next task or change the workflow description or even get a list of editions available or anything that could be run with from the command line could be run from this client server program.
if anyone needs more information let me know.
This client server program give a lot of power to teamsite processing since from anyserver (client) any teamsite information could be retrieved.
