Specified by:

displayPage in class SwitchedAction

Parameters:

info - The request info passed to SwitchedAction.act(CheckedAction.ActionInfo)

Returns:

The forward to go to

performAction

public org.apache.struts.action.ActionForward performAction(CheckedAction.ActionInfo info)

Description copied from class: SwitchedAction

This function is called when a request was submitted by an HTTP POST request. This function should actually perform whatever action the user wanted. You should probably strive to make it so that the URL that calls this action can only be POSTed to from the page displayed by SwitchedAction.displayPage(CheckedAction.ActionInfo) so that you know that the user is coming from that page.

Specified by:

performAction in class SwitchedAction

Parameters:

info - The request info passed to SwitchedAction.act(CheckedAction.ActionInfo)

Returns:

The forward to go to
