Here's the steps I did to test this, which worked:
1. modify struts-config.xml for an exception handler:
<global-exceptions>
<exception type="java.lang.Exception"
path="/Error_Page.jsp"
key="exception.servletexception"
scope="request"/>
</global-exceptions>
2. Force an exception in some action:
try { int i = 1/ 0;
}
catch ( Exception ex ) {
throw new ServletException("general failure error reading drive C");
}
3. Add entry to resources file: project1.ApplicationResources.properties
as defined by struts-config.xml:
<message-resources parameter="project1.ApplicationResources"/>
exception.servletexception=A catastrophic error occurred.
4. Defined an error page: Error_Page.jsp:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd";>
<%@ taglib prefix="html" uri="/WEB-INF/struts-html.tld" %>
<%@ page contentType="text/html;charset=windows-1252" isErrorPage="true" %>
<%@ page import="org.apache.struts.Globals" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252"/>
<title>Error_Page</title>
</head>
<body>
<html:errors/>
<br/>
<%
// read the Struts exception that is placed here by the default Struts
Exception handler.
Exception e2 = (Exception) request.getAttribute( Globals.EXCEPTION_KEY
);
if ( e2 != null ) {
// out.println( e2.getLocalizedMessage() );
e2.printStackTrace(new java.io.PrintWriter(out));
}
%>
</body>
</html>
5. test application:
Validation Error
You must correct the following error(s) before proceeding:
A catastrophic error occurred.
javax.servlet.ServletException: general failure error reading drive C
