webwork.action.factory.DefaultActionFactory

Direct Known Subclasses:

SpringActionFactory

public class DefaultActionFactory
extends ActionFactory

Default implementation of an action factory facade that creates the default set of action factory proxies. This class delegates to the proxies as implementation, thus acting as a facade to them.

The order in which factory proxies are executed is as follows:

1. ChainingActionFactoryProxy - Copies properties from one action to the next in a chain.
2. ParametersActionFactoryProxy - Sets parameters on the action.
3. PrepareActionFactoryProxy - Prepares or initializes the action.
4. ContextActionFactoryProxy - Establishes the action's context by executing methods for all implemented Aware* interfaces.
5. CommandActionFactoryProxy - Executes a specified "command" method if the action implements the CommandDriven interface.
6. AliasingActionFactoryProxy - Locates an action from the configuration substituting the alias with the associated action string.
7. CommandActionFactoryProxy - Executes a specified "command" method again in the event the original action name was originally an alias.
8. JspActionFactoryProxy - Returns the JSP action if its suffix is ".jsp".
9. PrefixActionFactoryProxy - Returns an action using a configured list of packages to prefix its name.
10. XMLActionFactoryProxy - Returns the XML action if its suffix is ".xml".
11. ScriptActionFactoryProxy - Returns the Script action if its suffix matches that of a supported scripting language.
12. JavaActionFactory - Returns an action object from a fully qualified classname.
