Coordinated Request Reply sample

The Coordinated Request Reply sample is a message flow sample application based on the scenario of two applications with different message formats that communicate with each other. One application has a message format of self-defining XML and the other uses Custom Wire Format (CWF) messages. The two applications communicate through the use of WebSphere MQ and JMS messages in a request/reply processing pattern. For the applications to communicate successfully, the message formats must be transformed on both the request and reply messages. An additional two applications demonstrate how to use the global cache to share data between two flows running in different integration servers

The Coordinated Request Reply sample has four applications and one library. The library has a reference to a message set and an Integration project, which are common to both applications. Applications and libraries introduce a way of creating and managing resources when you are developing and deploying applications, and during operational management.

The Coordinated Request Reply sample demonstrates how to store information for use by the Request and Reply flows by using a global cache or a store queue.

For more information about applications and libraries, see Applications and libraries in the IBM Integration Bus documentation.

For more information about using a global cache, see Global Cache overview in the IBM Integration Bus documentation.

The Coordinated Request Reply sample demonstrates the use of the following resources:

Using the Coordinated Request Reply WebSphere MQ sample
Using the Coordinated Request Reply JMS sample
Using the Coordinated Request Reply Global Cache sample
Using applications and libraries

NOTE: In WebSphere Message Broker Version 8.0, IBM Integration Bus 9.0 and later, message model schema files contained in libraries are the preferred way to model messages for most data formats, including the new DFDL domain. Message sets continue to be supported, and are required if you use the MRM or IDOC domains. You can continue to import and deploy message sets for use in message flows. However, if you need to create one or more message sets, message definitions, or message categories when using this sample, you must first enable message set development in the IBM Integration Toolkit. For more information, see Enabling message set development in the IBM Integration Bus documentation.

Setup instructions

You can set up the sample in one of the following ways:

Import and deploy the sample
This option imports the sample files into your workspace and deploys the sample to the integration node. This option also sets up additional resources for the sample, for example, WebSphere MQ queues. By default, the Coordinated Request Reply MQ application, Coordinated Request Reply Global Cache application and Coordinated Request Reply Backend application are deployed. The Coordinated Request Reply JMS application is not deployed because additional manual steps are required to configure the Coordinated Request Reply JMS application for testing.
Import the sample
This option imports the sample files into your workspace. You must define the queues that are required for the sample and set up the default configuration, activities that are beyond the scope of this sample and are not described in its documentation. Additional manual steps might be required to configure the sample for testing.

You can import or import and deploy a sample only when you use the information center that is integrated with the IBM Integration Toolkit.

Extend the sample

When you have finished with the sample, you can remove it in one of the following ways:
