 <  Day Day Up  >  

In this chapter, you learned

  • Controls have a well-defined life cycle, and you can hook life cycle events together by adding custom code.

  • Database and rowset controls are used to access existing database tables via DataSource s.

  • Custom database and rowset control methods are written to add, update, delete, and modify data using SQL statements coded with control methods .

  • Value objects can be both passed to and returned from database and rowset control methods. WebLogic Workshop provides sophisticated substitution mechanisms in support of value objects.

  • You can easily test database and rowset controls by using generated Web services that provide method-level interfaces to each control method.

  • Custom Java controls are easily created in WebLogic Workshop and can use other local and nonlocal controls quickly and easily.

  • Callbacks are a simple method for notifying a caller when a long-running operation has completed.

  • Callback methods are coded in both a control and a caller and are fully supported in WebLogic Workshop.
