Overview of the data-handler development process

To develop a custom data handler, you code the data handler source file and complete other tasks, such as developing a meta-object for the data handler. The task of creating a custom data handler includes the following general steps:

  1. Design the data handler, based on the format of the serialized data and structure of the business objects it converts.
  2. Create a class that extends the class:
    com.crossworlds.DataHandlers.DataHandler
    
  3. Implement the abstract methods that convert data between specific data format and business objects.
  4. Compile the class and add it to the CustDataHandler.jar file.
  5. Create the data-handler meta-objects.
  6. Develop business object definitions that conform to the requirements of the data handler as well as to the requirements of the caller.

Figure 35 provides a visual overview of the data-handler development process and provides a quick reference to chapters where you can find information on specific topics. Note that if a team of people is available for data-handler development, the major tasks of developing a data handler can be done in parallel by different members of the development team.
