RESTful Web Services Development with Java

Course:  RESTJ
Duration:  3 Days
Level:  II
Course Summary

This course teaches experienced Java programmers how to build RESTful web services using Java. The course starts with an overview of web services development on the Java EE platform, including SOAP, WSDL, REST, JAX-WS, JAXB, and JAX-RS. Students learn to work with JAXB to bind Java object models to XML Schema. The Jersey implementation is used 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 network.
