Folks, this may be an off topic question, but I am curious to understand why.
We know that Http protocol has features such as Headers. Both response and request
have HTTP headers. It is easy to get the headers in J2EE from a HttpServletRequest
objects using getHeader() and/or getHeaders()
() or
getHeaders() methods because the developer is setting
them. The HttpServletResponse interface has
addHeader() and addXXXHeader() methods to add headers
to the response. There is also the containsHeader()
method which returns a boolean.

If you want to find out which will be next page to go, you can create an ActionForward
object and customize the parameter.

Subject: Re: declaring action
HI,
I have a request to catch a Java Exception in the servlet and display an error page.
The functionality requires that we display different error message for different
exception.
A way to do this is to put try and catch logic in servlet, and if an Exception is
caught, I do
that to an Action, which could then
forward it to a custom page, or rethrow so a Struts exception handler could
grab it.

Subject: configure default error
I am using struts 1.1b3. When the validation fails, the error can be shown on the page
using html:errors. Now I have an action form page(say book.jsp, on this page there
is a required field-- book title), I want an error.jsp, when the validation (example,
title field is null) fails, the error
() 0 rather than != null.
