Business logic
Name-value pair command framework
The name-value pair framework is the only command framework that existed in releases of WebSphere Commerce Version 6, prior to Feature Pack 3.0.1. This command framework uses name-value pairs as input to the business logic layer, and returns the responses as name-value pairs.
Command error handling
WebSphere Commerce uses a well-defined command error handling framework that is simple to use in customized code. By design, the framework handles errors in a manner that supports multicultural stores. The following sections describe the types of exceptions that a command can throw, how the exceptions are handled, how message text is stored and used, how the exceptions are logged, and how to use the provided framework in your own commands.
