Method Detail

goForward

public org.apache.struts.action.ActionForward goForward(org.apache.struts.action.ActionMapping actionMapping,
                                                        String forwardName,
                                                        String[] urlParams)

Helps you forwarding from one one action to another action and carrying over the parameters. If not carried over, they disappear from the request scope during forward.

A common use case is to have the SaveAction invoke the DislayListAction. To do this in a fashion that changes the URL in the users browser, you set the redirect="true" in the action in struts-config.xml and by uisng this helper method. It will take whatever you info you provide and encode the url to redict to.

Parameters:

actionMapping - Your Struts object

forwardName - Name of the action in the struts-config.xml

urlParams - An array of strings where you already have set all the values as strings, e.g. strings such as "id=1", name="Mr. Anderson"

Returns:

A struts forwarderder object

Throws:

IllegalStateException - if redirect="true" is not set in the struts config or if forward path is invalid.
