Let's first discuss how to enable global exception handling.To enable global exception handling you need to add two nodes to struts.xml: global-exception-mapping and global-results. E.g. 404 (Page Not Found) pages can be better handled with a catch-all sitemap item The web.xml error pages should be used as a last fallback solution, when for example the HST sends a Let us put following code in main.jsp: Try...Catch Example <% try{ int i = 1; i = i / 0; out.println("The answer is " + i); } Errors are typically ignored in your code because you can rarely do anything about an error.

This enables us to use the 'exception' object on the jspW, as demonstrated in the scriplet code. Exceptions you do not catch in the JSP page will result in forwarding of the request and uncaught exception to an error page. For example if a SecurityBreachException is thrown but not caught, the Struts 2 Action class will return a result of "securityerror". How do I create a JSP error page to handle exceptions?

All other uncaught exceptions will cause the Struts 2 Action class to return a result of "error".The global results mapping node relates the result value to a specific view page. Handling error codes and exceptions by the web.xml In your web.xml you can configure error-page elements that act upon some error-code or exception-type.

Exception Handling is the process to handle the runtime errors. There may occur exception any time in your web application.
