Looks like we will have to create a Jaxb tree for struts and scan struts actions ourselves. I did find some struts facilities which will give me the info about all "struts actions", but struts provides us with that information after the webapp starts. We need this information "before" the app starts. So, for now, so that we can add atleast some support for struts actions.
