Step 4 - A Sample Server Application

In this section of the tutorial, you will use Chameleon to build a simple, but operational, server application that accepts incoming messages from a network, extracts data from the messages, and processes that data.

The generated classes discussed in the previous section will be used in this application, but you will require several additional components. Minimally, you will need:

• A means of capturing incoming messages from a network;
• A way of acknowledging to the sender that you received the message (a courtesy required by the HL7 standard); and
• Specific logic for processing the message.

Rather than writing the server application from scratch, you can use Chameleon to generate most of the code that you need.
