I've posted a small module that demonstrates how to utilize the Google Maps API geocoding services from within Servoy, using HTTP REST calls.
You pass in an address string, and get back a lot of useful information including longitude/latitude, postal codes, county, etc.
Google Maps conveniently will provide JSON formatted results, so it's quite easy to parse and use in Servoy.
Download the module here:

It's got a test form that demostrates usage, but you will need to signup for a Google Maps API key, which you can do here:
