[Wicket] Vs [HTTP 404 - File not found]
Hi Guys,
What is the preferred strategy for customization of error page under HTTP
404 - File not found situations, any helpful pointer will be appreciated.
At present i have used error directive in web.xml and I wonder how should i
go about it, if i want to handle this from within wicket.
Thanks

WicketFilter does exactly the same thing, but the response encoding is
already set (by container?) so it remains wrong.
It seems like the approach Igor mentioned works only if you use
ISO-8859-1 for your pages (at least under tomcat 5.5).

You probably need to write a servlet filter that wraps the entire
request that sets the encoding:
public class CharsetFilter implements Filter {
public void init(FilterConfig config) throws ServletException {}
public void destroy() {}
public void doFilter(ServletRequest request,
ServletResponse response, FilterChain chain)
throws IOException, ServletException
{
request.setCharacterEncoding("UTF-8");
chain.doFilter(request, response);
}
}

Igor,
I tried this approach under tomcat 5.5.17 but got problems with
character encoding. When WicketFilter gets the request to the correct
page (defined in the web.xml error-page/location) the request encoding
is already set (by tomcat?) to ISO-8859-1 and wicket can't change it. So
user gets a page with wrong encoding :-( Googling for the solution
didn't help.

Oops :-) Sorry, of course I meant 512 bytes :-)

I hope I don't have to download half a meg to find out my original
request couldn't be found ;)
But yes, you need to do some special processing to make the page
bigger than N bytes (512?) before IE thinks it can do better than you.

Hi,
I don't know the best way but we just created error404.html which
forwards to the home page. Notice that several lines of dots - they make
the response bigger than 512Kb, so IE doesn't show it's friendly 404
page. Please share your expirience if you have a better way to handle it :-)
