Java Web Services: Developing RESTful Services Training

Posted on by

This 3 day class shows experienced Java programmers how to build RESTful web services using the Java API for RESTful Web Services, or JAX-RS. We begin with an overview of web services development in the Java EE platform, including SOAP, WSDL, REST; JAX-WS, JAXB, and JAX-RS. Then students learn to work with JAXB to bind Java object models to XML Schema. The bulk of the course is devoted to study of JAX-RS: students work with the Jersey implementation of JAX-RS to create RESTful services from simple single-value interactions to more sophisticated services that manage CRUD (create/retrieve/update/delete) operations on more complex data types, using JAXB to marshal and unmarshal data over the wire.

Goals

  • Understand the advantages of the REST architecture for web services.
  • Use JAX-RS to develop simple RESTful services.
  • Control dispatching to service methods based on URL patterns and HTTP methods.
  • Bind request values to method parameters when expressed as HTTP query parameters, form values, headers, cookies, and more.
  • Manage XML content using XML Schema and JAXB.
  • Incorporate XML entities into service input and output.
  • Take advantage of lifecycle and context services available to JAX-RS services as Java EE components.
