SUMMARY:   Apache Axis2 is an implementation of the Simple Object Access Protocol (SOAP). Axis2 has a modular and flexible message handling pipeline. This course focuses on the details of message handling and providing clear hooks for implementations of associated Web Services standards and protocols. AUDIENCE:   Developers with some understanding of web services technologies and Service Oriented Architecture concepts. PREREQUISITES:   To benefit from this Axis2 training, students should have a proficiency in Java and XML, as well as a basic knowledge of: SOAP, WSDL, Web Services, Service Oriented Architecture. General understanding of Web servers and some knowledge of TomCat and Spring. DURATION:   5 days. OBJECTIVES:   At the end of this course, students will be able to: Understand SOAP, WSDL, and WS-Addressing. Understand Service Oriented Architecture and how to build one using Axis2 and Java. Better understand Web Services security and reliability. Install and configure Apache Axis2. Create and consume Web Services. Generate Services and Clients using command line and IDE tools. Make interactions secure and reliable. Understand Axis2 architecture. Understand all components/features of Axis2: AXIOM, Handlers, Phases, Policy, contexts. Use Axis2 Ant tasks and IDE plug-ins. Do Test Driven Development of Axis2 applications.
