public class DefinitionDispatcherAction extends Action
An Action that dispatches to a Tiles Definition
that is named by the request parameter whose name is specified
by the parameter
property of the corresponding
ActionMapping.
This action is useful in following situations:
To configure the use of this action in your
struts-config.xml
file, create an entry like this:
<action path="/saveSubscription"
type="org.apache.struts.tiles.actions.DefinitionDispatcherAction"
parameter="def"/>
<forward name="success" path="anything" //>
<forward name="error" path="path.to.error.page" //>
which will use the value of the request parameter named "def" to pick the appropriate definition name.
The value for success doesn't matter. The forward will forward to appropriate definition.
The value for error should denote a valid jsp path or definition name.
