Method Detail

changeForwardPath

public static org.apache.struts.action.ActionForward changeForwardPath(org.apache.struts.action.ActionForward forward,
                                                                       Map params)
                                                                throws Exception

Return a new ActionForward based on the given one but with the specified parameter name and value added to the new forward's path. NOTE: this method would be unnecessary if Struts allowed us to "unfreeze" the ForwardConfig that is the superclass of the forward.

Parameters:

forward - the ActionForward on which the new forward is based

param - the name of the path parameter to add

value - the value of the parameter to add

Throws:

javax.servlet.ServletException - if encoding the path parameter fails

Exception

                        throws Exception

Change a url by appending all of the params to it.

Parameters:

                             throws Exception

Return a URL path that will return control to the current action. This path is generated by adding the specified parameters to the path of the forward specified as the "input" forward for the given mapping.

Parameters:

mapping - the ActionMapping describing the current action's forwards

params - a map containing the path parameters to add

Throws:

javax.servlet.ServletException - if encoding the path parameter fails or input has not been set

Exception
