Course Description

  
This course 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.
