Documentation and code snippets can be found here: http://struts.apache.org/2.1.6/docs/bootstrap.html Basically, map your action in struts.xml, add the appropriate getter/setter in your action, and it should automagically be set from the url to your action. If that doesn't work, then there's something wrong with your setup.
