public class ServletActionRedirectResult
This result uses the ActionMapper
provided by the ActionMapperFactory
to redirect the browser to a
URL that invokes the specified action and (optional) namespace. This is better than the ServletRedirectResult
because it does not require you to encode the URL patterns processed by the ActionMapper
in to your struts.xml
configuration files. This means you can change your URL patterns at any point and your application will still work.
It is strongly recommended that if you are redirecting to another action, you use this result rather than the
standard redirect result.
