All Implemented Interfaces:
Serializable

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 associate an Url to a definition
      To use Struts <html:link> tag on a definition
  • 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.
