Customize JAX-RPC Web services and clients with advanced tools
This tutorial takes you beyond the basics of the JAX-RPC and shows how to customize your JAX-RPC Web services and clients with the help of Apache Axis. On the client side, you can autogenerate much of the code required to connect with new JAX-RPC Web services, focusing your time on the interactions themselves rather than on routine Web service calls. On the server side, you can add additional options, limit the methods you expose, and restrict parameters you'll accept. All of this is possible with a little customization and a deeper understanding of the Apache Axis toolset. |

video with your 500 closest friends is driven by a Web 2.0 application. With
more environments relying on Web 2.0, IBM has released WebSphere sMash, an
application framework designed around core concepts such as agile development,
simplicity, and REST-ful interfaces. While most WebSphere sMash examples have
user interfaces expressed using Ajax and either plain HTML or the Dojo Toolkit,
this article shows how a simple sample application can be enhanced to support a Web 2.0 user interface written in Adobe Flex. Server implementations are provided in both Groovy and PHP. This article is for intermediate developers who have experience using REST and developing with the Adobe Flex Development Kit. (IBM WebSphere Developer Technical Journal) |
Web Services for Point of Service applications, Part 1: Retail store peripherals and Web services with POS open standards
This article, Part 1 of a series, demonstrates how an emerging standard, Web Services for
Point of Service (WS-POS) peripherals, allows interoperability between retail
peripheral devices (printers, scanners) and point-of-service (POS)
applications, irrespective of the platform (Java or Microsoft .NET) to which
they are physically connected. All the major Web services players support the
Web services stack that's used to build the WS-POS open standard. This means
that peripherals aren't required to adhere to a single platform, but can
instead behave as true services. |
SCA asynchronous invocation patterns in depth
Service Component Architecture (SCA), a next-generation programming
model, provides three kinds of asynchronous invocation patterns. You
can use those patterns to asynchronously invoke target SCA services without
knowing how the request and response messages are "magically" processed. This
article explains what happens when you issue an asynchronous
request and how the SCA run time handles the asynchronous messages in the
messaging systems. Learn how to develop a
mediation handler to monitor the SCA asynchronous messages and how to use the mediation handler to analyze asynchronous
invocations. |
Develop XML-driven Ajax applications fast with Data Studio
Web services are a popular way to communicate data over the Internet in XML format; databases have long since been an integral part of any Web application. With Data Studio, developers can integrate the two by defining SQL and SQL/XML queries that you can automatically build and deploy as a Web service. In this tutorial, you'll develop a data-driven Web service using Data Studio and craft an Ajax application for the gaming industry where users can browse games they want to play, search for them by title, and even add, edit, and delete games. The Ajax application running on the client communicates with the gaming Web service in XML format, both of which are served on WebSphere Application Server. |

Describe REST Web services with WSDL 2.0
At their core, Web services define a mechanism for machine-to-machine
interaction using a network and XML. A key component of a Web service is a formal
description with Web Services Description Language (WSDL). Until recently there was
no formal language to describe REpresentational State Transfer (REST) Web services -- now there's WSDL 2.0. This
article introduces you to REST
and WSDL 2.0, and walks you through creating a WSDL 2.0 description of a REST Web
service. |
Increase business agility through BRM systems and SOA
The widespread acceptance of Service-Oriented Architecture (SOA) proves that
enterprises have realized the promise of this technology. That promise of increased
agility comes from a basic software design principle: loose coupling. SOA allows for
business functions to be exposed as independent services. Web services, which is one
way to implement SOA, makes any business functionality available over the Internet.
Another technology that promises to extend that agility to business users is
business rules management (BRM) systems. A BRM system gives business users direct
control over the business logic, allowing them to change it without much
intervention from IT. This article explores how these two technologies--SOA and
BRM--promise to help businesses respond more quickly and cost effectively to
changing market conditions. |
