Isn't it "requestScope" for accessing request attributes?
Not that this is Struts-related; if you're having problems with a third-party
tag library you should seek support through whatever mechanism they provide,
otherwise a generic JEE forum.
IMO it'd be cleaner to expose an action property and access it via JSP EL
rather than tying your action to the servlet spec.
