Before you start

IBM® WebSphere® Message Broker V8 (hereafter called Message Broker) provides the capability to integrate with existing Microsoft® .NET® Framework (hereafter called .NET) applications. You can do this integration by wiring the new Message Broker .NETCompute node into a message flow, or by calling a .NET application from an ESQL Compute node.

About this tutorial series

This series of four tutorials shows you how to use the new Message Broker .NETCompute node integration capability. Each tutorial shows you how to create C# code in Microsoft Visual Studio 2010 using an embedded template, which is provided by an installation of the WebSphere Message Broker Toolkit. The four tutorials explore the following topics:

1. Using the .NETCompute node sample
2. Using the .NETCompute node to integrate with Microsoft Word
3. Using the .NETCompute node to integrate with Microsoft Excel
4. Using the .NETCompute node for exception handling

About this tutorial

This .NETCompute Node sample filters, modifies, and transforms messages using code written in C#. You can use the .NETCompute node on Microsoft Windows® brokers to construct output messages and interact with the Microsoft .NET framework (.NET) or Component Object Model (COM) applications.

WebSphere Message Broker enables you to host and run .NET code inside an execution group. The new .NETCompute node routes or transforms messages by using any Common Language Runtime (CLR) compliant .NET programming language, such as C#, Visual Basic (VB), F#, or C++/Common Language Infrastructure (CLI). This tutorial describes the new .NET API provided by WebSphere Message Broker, which enables .NET developers to interact with Message Broker's logical tree.

Prerequisites and system requirements

This tutorial is written for WebSphere Message Broker programmers who want to learn about the new .NETCompute node, and for .NET programmers who want to learn about using WebSphere Message Broker. If you have a general familiarity with C# or with Message Broker, then you should find the tutorial relatively easy to complete.

To build and execute the example in this tutorial, you will need:

• A Windows installation that includes Microsoft .NET Framework V4
• WebSphere Message Broker (Toolkit and Runtime) V8
• Microsoft Visual Studio 2010 (Express Edition or Professional Edition) to write and build the required C# code

Sample files

You can import the message flow and test data for this tutorial from the Message Broker Samples Gallery, which is available as part of your Message Broker installation. No further downloads are required in order to complete this tutorial.
