Subject RE: global exceptions, key?
Date Thu, 28 Sep 2006 11:57:16 GMT
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.
