9.4. Using a Global Error Page
Problem
Your application should display the same error page for any server error or uncaught exception thrown from a Struts Action, a servlet, or a JSP page.
Solution
Declare a global error page, such as the one shown in Example 9-8, to handle all exceptions and errors in your web.xml file as well as your struts-config.xml file.
