Have a look at injecting the FacesContext and the request parameter related methods on the externalContext:

@In FacesContext facesContext;

private void hello() {
 Map<String, String> parameters = facesContext.getExternalContext().getRequestParameterMap();
 //or get the request itself
 HttpServletRequest request = (HttpServletRequest)facesContext.getExternalContext().getRequest();
}

Why not @RequestParameter?

Meant to include that.

Mind you the problem I've had with @RequestParameter is that you can't use the same Bean without providing it - ie. if it's not set then you get an error. How have you overcome this?

@RequestParameter(required=false)

@RequestParameter doesn't have a 'required' attribute.

You should open a feature request for @RequestParameter(required=false)
