With the widespread use of component technology, it has become increasingly important to employ components in distributed computing environments. Currently, a handful of distributed component platforms exists, including the Distributed Component Object Model (DCOM), Common Object Request Broker Architecture (CORBA), and Remote Method Invocation (RMI). A new addition to this list is Web services, a framework that has recently received considerable attention. "It's safe to say that every one of the software platform vendors out there will have to either support, or provide tools for, Web services at some point," said Simon Yates, an analyst with the industry research firm Forrester Research. Although the Web services market is still in its infancy, analysts say it will ha... (more)

Web Services and Distributed Component Platforms (Part 2)

As we can see from the tables, Web services measure up quite nicely with other distributed systems environments. The main differentiating characteristics are: Web services, unlike other distributed systems, support only remote communications, they don't support colocated services. Web services are implemented over HTTP, which is a connectionless protocol. Therefore, some important featur... (more)

Web Services Invocation Framework, part 2

The Web Services Invocation Framework (WSIF) is an architecture and programming model that - unlike today's most popular Web services APIs, JAX-RPC and JAXM - supports RPC and messaging invocation of Web services in a single programming model. In Part 1 of this series I introduced WSIF and described its architecture and programming model. In this article I will discuss more advanced topic... (more)

Web Services Invocation Framework

Today's most popular Web services APIs - JAX-RPC and JAXM - support two very different programming models for invocation of Web services, one synchronous, one asynchronous. If users need both models in a single application, they are forced to use two sets of very different APIs. This article, the first of a two-part series, describes an architecture and programming model - the Web Servic... (more)

Implementing J2EE/.NET Interoperability Using WebSphere MQ Part 2 - Putting theory into practice

In Part 1 of this series, we discussed how the use of messaging software can alleviate some of the problems with integration of J2EE and .NET environments using Web services. In this article we will discuss implementation of the proposed architecture on both J2EE and .NET platforms, along with possible enhancements of the proposed solution. All of the code referenced in this article is av... (more)
