Re: How to specify an Error Page in a servlet

Hi,

Any of the following ways would help you to handle your errors/exceptions:

1. Using <error-page> element in your web.xml, you can specify
which JSP/Servlet should handle what exception(s)/error code(s).

Web Container would pass the following (among 5 request attributes) to your
handler :
        i) javax.servlet.error.status_code
        ii)javax.servlet.error.exception

Note 1: You should not catch those exceptions mentioned in
<error-page></error-page>
          Those exceptions are supposed to be handled and redirected by the
container
          to the error page resource(jsp/servlet) defined in the deployment
descriptor

Note 2:

2. RequestDispatcher.forward(...)
        - You can pass the exception/error code as request attribute to the
handler(servlet/jsp)

3. HttpResponse.sendRedirect(...)

Subject: How to specify an Error Page in a servlet


Hi all,

Can someone please tell me how to specify an Error Page in a servlet similar
to JSP's errorPage attribute of the page tag.

<%@ page language="java" buffer="8kb" autoFlush="true" isThreadSafe="true"
isErrorPage="false" errorPage="ErrorPage.jsp" %>.


Thanks
