URL Mapping

The mapping of the URI path space is presented in the following table:

URI path	Resource class	HTTP methods	Allowed values
/api/contact	ContactCardResource	GET, POST, DELETE
/api/contact/{id}	ContactCardResource	GET, DELETE	id - positive number
/api/contact/search/{searchType}?q={searchValue}	SearchResource	GET	searchType - (name

Application is configured by using web.xml, which registers javax.ws.rs.core.Application descendant to get classes and singletons from it (see class MyApplication). Bean Validation annotations are present on resource classes (see ContactCardResource, SearchResource) as well as on the domain class (see ContactCard).
