    This IBM® Redpaper™ publication introduces the concept of a service-oriented architecture (SOA). The intended audience is web developers interested in SOA. It explains how to realize this type of an architecture using the following Java Enterprise Edition (Java EE 6) web services specifications:

    • Java Specification Request (JSR) 224: Java API for XML-Based Web Services
    • (JAX-WS) 2.2

    • JSR 311: Java API for RESTful Web Services 1.1 (JAX-RS)
      • It explores the features that are provided by IBM Rational Application Developer for web services development and security. It also demonstrates how Rational Application Developer can help with testing web services and developing web services client applications.

        The paper is organized into the following sections:

        • Introduction to web services
        • New function in Java EE 6 for web services
