Web Services with Apache Axis Training Summary

Web Services with Axis class teaches students how to build web services and web service clients using Java technologies and Apache Axis, the most popular JAX-RPC implementation. The class starts off with a quick introduction to XML, SOAP, and WSDL before diving into the development of web service clients, and end-points using Java/Axis APIs and tools.

Web Services with Apache Axis Training Objectives

Understand the connection between web services and Service Oriented Architecture (SOA)
Understand the difference between document-styled services and RPC
Become proficient in technologies used as the foundation of web services: XML, Namespaces, Schema, SOAP, WSDL and UDDI
Learn common design patterns and best practices for architecting highly interoperable web services
Learn how to implement web services using Apache Axis
Understand how to map WSDL/Schema elements to Java objects
Understand Web services security and reliability

Audience for Web Services with Apache Axis Training

This course is designed for software developers and architects who wish to learn how to design, build, deploy, and consume web services through Java and Apache Axis technologies.

Web Services with Apache Axis Training Prerequisites

To benefit from this course, the students need to be proficient in Java and principles of object-oriented design and development. Previous familiarity with XML, SOAP, WSDL, web services, and SOA can be beneficial, but is not required.

Additional Notes for Web Services with Apache Axis Training
