Map Service definition files live in the “services” folder. MapRequest loads all .properties files in this folder when it starts up. (Note that any files that do not specify a valid driver class are ignored.)
Each file defines a mapping service that can be used to request maps. The most important parameter is the one defining the driver class.
Note that any .properties files that do not define a driver are silently ignored.
Service definition files use standard Java .properties files syntax. Note that this means that they should use only ASCII characters. Non-ASCII characters are specified using Unicode escape sequences in \uxxxx notation.
MapRequest has drivers for ArcIMS and WMS based map sites.
