jsp - Send error with attribute

Question

I'm sending a custom error page for 404 in jsp. But I want to know if it is possible to add attributes to page, as request dispatcher does it.

I have a user session to bar with some information, like its name, and other things, and I want to that page contains the same top bar. It is possible in this way of sending error pages?

Thanks.

You can define custom error pages in your web.xml and you can access the session in the error-page code.

<error-page>
  <error-code>400</error-code>
  <location>/WEB-INF/jsp/errorpages/ErrorPage400.jsp</location>
</error-page>

web.xml is described fully here: http://docs.oracle.com/cd/E13222_01/wls/docs81/webapp/web_xml.html

Look at documentation from oracle here: https://docs.oracle.com/cd/E19316-01/819-3669/bnahi/index.html

For example, the error page for Duke’s Bookstore is as follows:

<%@ page isErrorPage="true" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core"
     prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt"
     prefix="fmt" %>
<html>
<head>
<title><fmt:message key="ServerError"/></title>
</head>
<body bgcolor="white">
<h3>
<fmt:message key="ServerError"/>
</h3>
<p>
: ${pageContext.errorData.throwable.cause}
</body>
</html>
