To extend operations, do one of the following:

In general, you should first create a small set of generic operations that implement any of the interfaces or extend any of the basic operation classes. Each generic operation addresses a generic operation flow. You then extend the generic operations to create specific operations that have specific behavior. Create a set of reusable operation steps and, whenever possible, use these steps to implement the operation's flow.

For applications that use the Java Channel or require a separation of client and server operations, create subclasses implementing the ClientOperation or ServerOperation interfaces or extending BTTClientOperation or BTTServerOperation to create operations for execution in each environment. A generic operation should address the generic behavior for all the operations and you should only need a few of them. These must contain almost all the code needed for all the operations and they must also include the corresponding exits that extending operations are to execute.
