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:

• Specific logic for filling the message's tables with data prior to generation;
• A means of sending outgoing messages over a network; and
• A means of receiving, from the message recipient, an acknowledgement that the message was safely delivered (a courtesy required by the HL7 standard).

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