Download free the JavaTM BluePrints book "Designing Web Services with the J2EETM 1.4 Platform: JAX-RPC, SOAP, and XML Technologies" for a best practices guide to designing and integrating enterprise-level web services using the JavaTM 2 Platform, Enterprise Edition (J2EE) 1.4.

This book is meant to help readers develop robust and effective web services on the J2EE 1.4 platform or later. Authors Sean Brydon, Greg Murray, Vijay Ramachandran, Inderjeet Singh, Beth Stearns and Thierry Violleau present guidelines for using technologies to design and develop web services. Many of these guidelines have been formulated from their own web service development experience, which they illustrate with real-world examples.

With the added web services features to the J2EE platform, enterprises can benefit from:

• The ability to extend existing enterprise applications to web services in a manner that is standard, easy, portable and interoperable

• The ability to extend the reach of existing and new enterprise applications to a new set of clients beyond the already wide variety of clients supported by the earlier J2EE platforms

• The ability to use commercially proven, robust technologies, such as enterprise bean components, servlets and others, as the backbone for developing new services

• The ability to integrate existing enterprise information systems (EISs) to end users in a portable way

"Significantly, the J2EE platform adds portability to web services. By combining portability and interoperability, the J2EE platform is a compelling platform for developing distributed systems," the authors write. "This web-service evolution of the J2EE platform has been achieved with the same open process as before involving leading enterprise computing vendors. It has ensured that the J2EE platform is the platform of choice for developing and deploying portable and interoperable web services and enterprise applications."

Key topics covered include:

• Web service requirements and design issues
• Support for web services provided by the J2EE 1.4 platform
• Designing and implementing web service end points
• Writing efficient web service client applications
• Designing and developing XML-based applications
• Integrating applications and data using web services
• The J2EE platform security model as it applies to web services
• A coherent programming model for designing and developing web service endpoints and clients
