Why can't you access the HttpServletRequest object using
ServletActionContext.getRequest() and then just use the getParameter()
method to get the request parameters?
If you're getting a ClassCastException it's because you're casting
something that isn't a String to a String. Find out what the type of
that object is and go from there. It's simple debugging really.
