Subject I want to use an JSP-Error-page to catch the Exception from an XML-Page
Date Fri, 10 Nov 2000 09:48:09 GMT

I use Cocoon 1.8 ( XML, XSP and XSL)  to generate dynamic HTML-Pages.
Now I want to catch the Exception, wich happen in the XSP-Logic. I want to
send this Exception with an email. But I don't know how can I get the
Exception.

Can I do it with an JSP-Page?

The following have I add to the web-xml-File:

<error-page>
      <error-code>500</error-code>
      <location>/test.jsp</location>
</error-page>

Thats the test.jsp-File:

<%@ page info="Exception-Page" isErrorPage="true" %>
<html>
<head><title>Exception-Page</title></head>
<body>
Fehler: <%= exception.toString() %>
</body>
</html>

If the test.jsp-File call from the server, following exception happen:

javax.servlet.ServletException

I don't know, whether or not I can catch the Exception with an JSP-Page.

Are there any other posibilities?
Thank you in advance!
