> WebContext should not be an abstract class.  ServletWebContext should not be a concrete
class. 
> Different applications may want to have different base implementations of context but
still have WebContext methods. A perfect example is in Struts 1.3: WebActionContext and ServletActionContext
duplicate many of the methods in their chain equivalents without adhering to a common interface.
> I use the classes below in my application. Most Commons projects do not use the "IXxxx"
 interface naming convention but I had no choice here.
> public interface IWebContext extends Context
> {
>     public Map getApplicationScope();
>     public Map<String, String> getHeader();
>     public Map<String, String[]> getHeaderValues();
>     public Map<String, String> getInitParam();
>     public Map<String, String> getParam();
>     public Map<String, String[]> getParamValues();
>     public Map getRequestScope();
>     public Map getSessionScope();
> }
> public interface IServletWebContext extends IWebContext
> {
>     public ServletContext getContext();
>     public Map<String, Cookie> getCookies();
>     public Cookie deleteCookie( final String cookieName );
>     public HttpServletRequest getRequest();
>     public HttpServletResponse getResponse();
> }
