Here is a simple example of JSP error page that shows the error code and the URL of the requested page:

404.jsp:

<%@ page language="java" isErrorPage="true" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>



    
    


    Back to Previous Page
    
404 Page Not Found.
    

    
Error code: ${pageContext.errorData.statusCode}
    
Request URI: ${pageContext.request.scheme}://${header.host}${pageContext.errorData.requestURI}

Useful reading:

• "JSP.1.4 Error Handling" section in the JavaServer Pages Specification (JSR 245).
• Handling JSP Page Errors (from the official Java EE 5 Tutorial)

P.S.
The use of scriptlets inside JSP is highly discouraged. Read this post.
