The Oracle Business Rules Editor is a declarative component that can be embedded in any ADF-based web application. The component renders the user interface for rules editing and handles all events associated with rules editing. The Rules Editor uses the Rules SDK2 API to create and edit rules.

Using the Rules Editor, you can create, delete and edit the general rules, verbal rules, and decision tables that are part of a single ruleset. You are required to specify a RuleSetModel object, which is a wrapper around the Rules SDK ruleset object, as a parameter to the Rules Editor component. If multiple rulesets are required to be modified, multiple Rules Editor components must be instantiated, one for each ruleset.

The Rules Editor component performs the following functions:

• Creates, updates, and deletes:

  • Rules in a ruleset, as shown in Figure 26-1.

  • Simple tests or conditions in a rule, as shown in the IF area.

  • Actions in a rule, as shown in the THEN area.
