Handling exceptions in jsp
What is the diference between using
<%@ page errorPage="foo.jsp" %>
and declaring within web.xml
<error-page><error-code>404</error-code><location>/foo.jsp</location></error-page>
<error-page><error-code>500</error-code><location>/foo.jsp</location></error-page>
Which is better to use and why?
Thanks

I'd go for the second, largely because if you introduce a better error page later on, it's a minor config change rather than a code change, and the re-deployment overhead that goes with it. and also you can explain to a non-programmer how to change config a lot easier than code
One point and one comment
Point: Your error page needn't be another jsp. You can just as well declare a static HTML page as the attribute to errorPage.
Comment: If you use a static page, I don't believe you can capture information about the exception thrown as you can in a jsp [via error.getMessage()].
