Re: [Webwork-devel] Servlet 2.2 support

[Scott F. <sc...@at...>]

Todd,

HttpServletResponseWrapper is not dependant on anything else in 2.3 
AFAIK, so you could probably include it in your webwork.jar file.

Else you could just rewrite IncludeTag.ServletResponseWrapperInclude to 
implement HttpServletResponse.  You will be up and going with the 2.2 
spec in no time.

Cheers,
Scott
