Thanks to Sameer on his excellent presentation covering webservices. He discussed the current state in development with webservices including best practices, document oriented webservices, and what people are doing today. Sameer also delved into WS-I which is clarifying the ambigious portions of the existing specifications and providing profiles to verify interoperability. WS-I is composed of over 150 companies. Both Apache Axis and the Java Web Services Developer Pack are WS-I compliant. The Java Web Services Developer Pack is free implementation of the JAX-RPC spec and is a core piece of the Java Application Platform Suite. For an additional fee, a version can be purchased that has additional load-balancing/fault tolerance features. With the Web Services Developer Pack Sun is also providing early access to new technologies including WS-Security. Since both Apache Axis and the Java Web Services Developer Pack are JAX-RPC implementations, it should be possible to easily switch between implementations. Sameer covered the difference between Document Literal and Document Encoded services and their impact upon interoperability.

Abstract

The Java 2 Platform, Enterprise Edition (J2EE) version 1.4 has evolved to integrate web service and web services are now one of the many service delivery channels of the J2EE platform. Architects and developers are rapidly adopting the use of XML as the data format and a J2EE based technology stack to develop web services that either expose core business functionality to business partners or as a mechanism to integrate applications within the enterprise and eliminate vertical application silos.

This session will expose the audience to some of the different enabling API and specifications supporting web services in J2EE 1.4. There will also be a discussion of different architectural choices and the associated trade offs, various alternatives and best practices that architects and developers should keep in mind when building document driven web services on the J2EE platform.
