The Complete Java™ Web Services class teaches students how to build Web Services and Web Service clients using Java™ Technologies. The class includes a high-speed introduction to XML syntax, namespaces, XML Schema, SOAP, and WSDL before exploring Web service client or server-side development in Java APIs and tools. The course focuses on implementation using Apache Axis, the most popular Java™ JAX-RPC implementation.
Learning Objectives:
Understand how Web services relate to Service Oriented Architecture
Become familiar with the pillar Web service specifications for XML, XML Schema, SOAP, WSDL and UDDI
Pick up design patterns and best practices for Web service interface documents
Experience the development of Java Web services using Axis
See how WSDL and Schema elements map to Java objects
Recognize and understand the difference between RPC and Document styled services
Learn how to make and test Web services that are highly interoperable.
