/** Console Application to test the dynamic SOAP server dlls in a simple commandline environment.
  * @file ConsoleMain.cpp
    It tests the same SOAP server shared libraries that can be later deployed in the Apache server.
    to test it do the following: Start this program, open a commandline prompt window,
    change to the build output directory and enter.
