Overview of Java Web Services


Overview of Java Web Services – 1 Day

Course Description

This Overview of Java Web Services training course provides an overview of web services development in the Java EE platform, starting with a look at interoperable standards and then delving into Java technology to implement them. We look at both the SOAP-oriented and RESTful schools of service architecture. Then we look at examples of services developed using the APIs that are standard to the Java EE 6 platform: JAX-WS, SAAJ, and JAX-RS in particular.

Though it includes plenty of code and message-content details, and some short labs at the end of the day, this course is intended to be useful both to Java developers and to non-developers who wish to gain familiarity with the key concepts of web services and Java WS technology.

What You Will Learn

  • Be able to describe the interoperable web services architecture, including the roles of SOAP and WSDL.
  • Understand the importance of the WS-I Basic Profile for interoperable web services.
  • Build simple web SOAP services using JAX-WS.
  • Build simple web RESTful services using JAX-RS.


Java programming experience is assumed, and is necessary for the lab exercises. But those without Java skills can still profit from taking the course, so this is not a hard prerequisite.

Server Support: GlassFish

  • This version of the course works with the GlassFish server. Our Java EE courses are available in variants that support various server products, including Tomcat, GlassFish, JBoss, and WebLogic. For more details, and to find a desired server-specific version of a course, see our server-support matrix.

IDE Support: Eclipse Helios

  • In addition to the primary lab files, an optional overlay is available that adds support for Eclipse Helios. Students can code, build, deploy, and test all exercises from within the IDE, and take advantage of built-in editors, integrated debugging, etc.
