Using the
struts exception handlers, I think you can only catch exceptions thrown from Action classes. Exceptions could be thrown from JSPs and your request processor class which you will need to handle.
The
JSP errors can be handled using the "page" directive isErrorPage and errorPage attributes. You could use try-catch too in your JSP and even in your request processor class. You can also handle exceptions thrown from a
servlet in the web.xml by using <exception-type>.
