Creating REST Services

The following tools and frameworks are used in the SDK for creating a REST Web service:

• RESTEasy Framework (a framework for creating REST Web services)
• JBoss AS version 4.2.3.GA (used for deployment)
• Hornet-Q REST interface (used for notifications)
• Eclipse Indigo (the Java IDE)

The following options cover how to create REST services:

• Understanding Collections (Primary and Secondary) and HATEOAS.
• Creating RESTful WebService with Custom Media Types along with media type Versioning.
• Using and applying REST frameworks:
  
  
  • Handling Exceptions —This section describes a mechanism by which exceptions identifying common error conditions can be thrown in the EJB code, and mapped to Standard HTTP Status Codes.
    
  • Sorting, Paging, Filtering, and Field Selection on Collections—This section describes the usage and application of server side sorting, paging, filtering, and field selection. The usage includes how to leverage the provided functionality, whereas the application of this feature enables you to enable a REST API to support it.
  • Authentication and Authorization—This section describes how to secure a REST API (RBAC-based security) so that only an authenticated and authorized user can access it.
  • Notification—Notification framework is used to push notifications from server to client. This section describes the usage and application of this framework.
  • Tagging—The grouping or ungrouping of objects is termed tagging or untagging, respectively. This section describes the usage and application of this framework to tag and untag the relevant objects.
  • Discovery—It is important that each RESTful Web service publishes its metadata to be consumed by automated applications or by users. This section describes the usage and application of this framework to enable or disable the discovery of a RESTful Web service.
• Consuming a REST API from another RESTful WebService or an EJB seamlessly using JSServiceClient or JerseyClient.
