Since its introduction, web service has become a standard mechanism for integration between applications. However, there are many applications written in languages that do not provide a strong support for web service - for example Visual C++ V6.0 or Visual Basic V6.0. One approach to enable these applications is to have an adaptor that can convert a request into a web service call. This tutorial describes how to develop this adaptor implemented as a DCOM server using C#. It basically receives a COM request and forward the request to a web service endpoint. It also provides steps on how to make a COM request in C++ and shows steps on how to implement a Java web service. In short, it demonstrates how web service interoperability on the .NET and JEE platform can be achieved. C# code is developed using Microsoft Visual Studio, while the web services is developed using Rational Application Developer V7.5 and deployed on the WebSphere Application Server V7.0 test environment.
