Course description

Java is a very important part of Internet usage or services, thus being able to deal with web services in Java is also very important. This course will cover many of the necessary aspects of dealing with the Java API for XML (JAX) Web Services. The course will start with basic introductions to the Eclipse programming platform and Web Services and then move on to Basic XML Schemas and Schema Content Management. From there, Java API for XML Binding (JAXB) will be covered and JAX-WS will be introduced. Once the basic foundation is covered the course moves into the start of web services with Declarative Service Configuration, Web Service Description Language (WSDL) and Configuration Management, as well as introducing JAX-WS 2.0.

Prerequisites

This course is intended for Java programmers with beginner level knowledge of Java EE and XML.
