either inside the page or outside the page (such as in a called JavaBean). This section describes the JSP error processing error page in jsp example mechanism and provides a simple example. Using JSP Error Pages
Web.xml Error-page Example
Any runtime error encountered during execution of a JSP page is handled using the standard Java web.xml error-page exception-type exception mechanism in one of two ways: You can catch and handle exceptions in a Java scriptlet within the JSP page itself, using standard Java exception-handling web.xml error-page location code. Exceptions you do not catch in the JSP page will result in forwarding of the request and uncaught exception to an error page. This is the preferred way to handle JSP errors. You can specify the URL of an error page by setting the errorPage parameter in a page directive

in the originating JSP page. (For an overview of JSP directives, including the page directive, see "Directives". ) In a servlet 2.2 environment, you can also specify a default error page in the web.xml deployment descriptor with instructions such as the following:

You can have following type of errors in your JSP code: Checked exceptions: Achecked exception is an exception that is typically a user error or a problem that cannot be foreseen by the programmer. For example, if a file is to be opened, but the file cannot be found, an exception occurs. These exceptions cannot simply be ignored at the time of compilation. Runtime exceptions: A runtime exception is an exception that occurs that probably could have been avoided by the programmer. As opposed to checked exceptions, runtime exceptions are ignored at the time of compliation. Errors: These are not exceptions at all, but problems that arise beyond the control of the user or the programmer. Errors are typically ignored in your code because you can rarely do anything about an error. For example, if a stack overflow occurs, an error will arise. They are also ignored at the time of compilation. This tutorial will give you few simple and elegant ways to handle run time exception/error occuri

This element creates a mapping between the error-code or exception-type to the location of a resource in the web application.error-code - an integer valueexception-type - a fully qualified class name of a Java Exception typelocation - location of the resource in the webapp relative to the root of the web application.
