Subject Re: Need to Know how web services client /server will get the info to develop the payload to send to the opposite side.

Thanks josef.
Answering your questions.  Actually we are working on linux environment.
we have a linux server written in C,and we need somehow the linux server
should contact the webservice already running in the other network.
So we need some webservice and client to do the job of the linux server. so
we thought we will develop the service and client in the axis2C to the
contact the webservice in the other network.
Here i come to know Axis2c will be run as a module in the Apache HTTP
server.

So currently what we need to know is how the linux server will contact the
Axis2C module running in the Apache HTTP server for giving the inputs for
sending the payload.
