Hi, As suggeseted I switched to JSTL 1.0 I'm running my application using Tomcat 4.1.30.
Below is the content of my error page. <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %> <%@ page language ="java" import="java.util.*,javax.servlet.http.*" isErrorPage="true" %> <table cellSpacing="0" cellPadding="0" width="90%" align="center"> <tr> <td align="middle" class="msg" valign="center" width="50%"> <c:choose> <c:when test="${exception.class.name == 'com.structs.InvalidParameterException'}"> Exception is InvalidParameterException. </c:when> <c:otherwise> Exception is not InvalidParameterException. </c:otherwise> </c:choose> </td> </tr> </table> If I'm not wrong 'exception' is an implicit object available to a JSP. But I never see the when part of content getting printed even if InvalidParameterException is thrown. I also tried <c:when test="${exception.getClass().getName() == 'com.structs.InvalidParameterException'}"> But this time it encountered some parsing error. How exactly an object instance is passed to a JSTL tag? I'm not very clear on that. Let me know where I'm doing wrong.

With them, I'd construct the following for >your scenario: while this is a good general suggestion, neither tag library makes it easy to deal with the class of an exception. I suppose technically you could use bean properties to test against the string form of an exceptions' class name: <c:if test="${ex.class.name == 'java.lang.IllegalStateException'}">..</c:if> but you might simply find Struts' own declarative exception handling to be a more straightforward way to deal with this...
