Requirements for a Working Application

The generated classes discussed in this section are to be used in the context of an application. They do not, however, constitute a working application. To create a working application, you need at least the following:

• 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.

In the next section of the tutorial, you will use Chameleon to generate code that satisfies these requirements.
