About the Web Service Host sample

The Web Service Host sample shows you can invoke a legacy application as a web service. In this sample, the supplied legacy application is invoked by sending a WebSphere MQ message to a queue. The format of this message is mapped to a C header file.

The sample comprises two message flow paths, implemented in a single message flow. The message flow is designed so that multiple instances of the Web service can run concurrently. This is achieved by storing the HTTP context (reply identifier) in a "state" queue along with the correlation identifier of the message sent to the legacy application.
