HttpServletResponse.sendError(): need redirect to error page

I have the following code in doFilter() method, where I get application scoped bean.



I mapped 503 code to specific error page in web.xml. And I really get content of error page in browser, if error occurs. But the address in address bar doesn't change for error page address: an address of requested servlet leaves there. Is it right behaviour?
I'd like to inform explicitly about redirection to error page. Is it only possible with sendRedirect() and sendError() is not useful here?

Why would it be important that the URL of the error page be displayed? It's not. That's not the page that was requested. The behavior you are seeing is correct.

Thanks. I just thought that it is better approach to display error page address.

Why? That's not the page that was requested. What advantage would there to be to displaying the URL of an error page?
 
It is sorta covered in the JavaRanch Style Guide.
