How to generate SOAP message with WCF?

Write a C program to develop message-oriented middleware?

• Create three message queues. Allow various processes to become subscriber of any of these queues. Few processes may become subscriber for multiple message queues. Define three independent processes as message producer. Each message producer is responsible for writing messages to a specific message queue assigned to it. Allow numbers of messages to be written to these three message queues. Generate few (5-10) individual and independent processes. Each message consumer should read appropriate message from the message queue to which it defined as a subscriber. Define proper action for each message consumer after receiving messages.

• Answer:

  You would make one message queue server that listens to two TCP socket for connections. There would be two TCP listening ports, one for writers, and another for readers. A producer connects to the message queue server writer port and sends a message. The message queue server go through the list of connected readers (consumers), and forward the message to all of them. To have three queues, you run three instances of your message queue server, and give each instance different listening port numbers using command line parameters.
