How to handle error object in JSP using JSTL tags?

JSP Java 8 Object Oriented Programming Programming

You can make use of JSTL tags to write an error page ShowError.jsp with better structure and more information −

<%@ taglib prefix = "c" uri = "http://java.sun.com/jsp/jstl/core" %>
<%@page isErrorPage = "true" %>

<html>
   <head>
      <title>Show Error Page</title>
   </head>
   <body>
      <h1>Opps...</h1>
      <table width = "100%" border = "1">
         <tr valign = "top">
            <td width = "40%"><b>Error:</b></td>
            <td>${pageContext.exception}</td>
         </tr>
         <tr valign = "top">
            <td><b>URI:</b></td>
            <td>${pageContext.errorData.requestURI}</td>
         </tr>
         <tr valign = "top">
            <td><b>Status code:</b></td>
            <td>${pageContext.errorData.statusCode}</td>
         </tr>
         <tr valign = "top">
            <td><b>Stack trace:</b></td>
            <td>
               <c:forEach var = "trace"
                  items = "${pageContext.exception.stackTrace}">
                  <p>${trace}</p>
               </c:forEach>
            </td>
         </tr>
      </table>
   </body>
</html>

Access the main.jsp, the following will be generated −

Opps...

Error:	java.lang.RuntimeException: Error condition!!!
URI:	/main.jsp
Status code:	500
Stack trace:	org.apache.jsp.main_jsp._jspService(main_jsp.java:65) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:68) javax.servlet.http.HttpServlet.service(HttpServlet.java:722) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:265) javax.servlet.http.HttpServlet.service(HttpServlet.java:722)
