Type: Classroom course
Level: Intermediate
27 July 2005
About this course
This three-day instructor-led course is intended for developers who will build J2EE Web services based on the JAX-RPC and Web Services for J2EE specifications. Students learn how to develop Web services using the tools provided by IBM Rational Application Developer for WebSphere Software V6. This includes developing Web services using the Web services wizards, debugging and monitoring Web services using the TCP/IP Monitor, configuring handlers and security in Web service deployment descriptors, and using the WS-I tools to develop interoperable Web services. Students also learn how to package and deploy J2EE Web services to the IBM WebSphere Application Server runtime environment. Hands-on exercises which complement the lectures will be provided throughout the course.

Audience
This course is intended for developers who are seeking to expand their
expertise in securing, configuring and developing interoperable Web service
applications. The course assumes that students already understand the Java
programming language, and have some experience in developing Web services.
Objectives
After completing this course, students should be able to:
Develop and deploy J2EE Web services using JAX-RPC service endpoint and
stateless session EJB.
Build a stateless session EJB Web service that employs SOAP over JMS for
messaging and transport.
Debug and monitor Web services using the TCP/IP Monitor.
Configure SOAP message handlers and WS-Security support for Web services
using the Web service deployment descriptors.
Create J2EE Web services that comply with the WS-I Basic Profile
Prerequisites
Students are expected to have experience with J2EE Web services development
using SOAP and WSDL. To obtain the necessary prerequisite knowledge of
Web services technology, students can attend the following course:
