SOAP & WSDL Exchange Rate Conversion service

## Exchange Rate Conversion Example

- This example is an exchange calculator in two versions: based on VSP and soap_call() and another AJAX version based on WebService Behaviour. A virtual directory is configured to respond to SOAP service requests, which are handled in the context of the assigned SQL user.

- The example defines the following service descriptions and links:

  - A SOAP directory of 'exchange' for describing exch's procedures. The WSDL file will be located at http://hostname:[port]/exchange/services.wsdl

  - The server-based webservices file is exchange_rates.vsp, while the AJAX one is exchange_rates_ajax.html. Click on the 'Run' links to experience the demo.

- Note: loading the exchange.sql file will take some time, as it accesses a foreign host.
