where to find the class's names
I see this usage of attribute as below:
<%
String requestURI = (String)
request.getAttribute("javax.servlet.error.request_uri");
%>
Could anybody tell me where is that javax.servlet.error.request_uri
defined?

Hi !
The easiest thing would be to do as you where told when you subscribed to
the list, there is no reason to use that kind of language here.
"Please save this message so that you know the address you are
subscribed under, in case you later want to unsubscribe or change your
subscription address."
...
To remove your address from the list, send a message to:
<to...@jakarta.apache.org>
That's it.
Mikael

Doh - please forgive me - I didn't see I was responding to an already
correct response. Didn't mean to imply I was smarter than Craig - I
just can't read.....

javax.servlet.error.request_uri is a key that accesses a value stored in
the request somewhere (presumably from a servlet that forwards to this
JSP). There is no class javax.servlet.error.request_uri.
So there's probably a servlet that actually forwards to this JSP that
looks something like:
request.setAttribute("javax.servlet.error.request_uri",
"some_error_page.jsp");
getRequestDispatcher("the_jsp_you_are_reading.jsp").forward(request,
response);

Note that this is not the name of a *class* - it is the name of a *request
attribute*.
It's defined in the Servlet Specification, which you can download from:
http://java.sun.com/products/servlet/download.html
In the 2.3 spec, see Section 9.9.
Basically, if you declare an <error-page> to handle a particular type of
exception or HTTP status code thrown by your servlet, the container will
set a number of request attributes for you before calling your error page.
In particular, the attribute you describe above tells you what request URI
caused the error to occur - other attributes include things like the
exception that was thrown.
