The first 3 context parameters identify uniquely the version number of INTGeoServer. They are displayed in the serverinfo web service.

The IvaapServlet class is the generic class that does a lookup for all request handlers defined in the lookup. To add your own web service, you do not need to modify the web.xml file. Just implement the com.interactive.ivaapapi.server.requesthandlers.AbstractServiceRequestHandler class and register it in the lookup. For example, the request handler for the About web service is registered as follow with the @SelfRegistration annotation.
