out of our control. For obvious reasons, filling a user's screen with a Java primefaces error page stack trace is not the optimal solution in these situations. Instead, we'd like to provide the user with a simplified indication jsf exception handling example of the error condition, and provide some options for recovery. In this article we will look at how error handling may be implemented for applications written using MyFaces/Facelets. 1. The Servlet Specification The Servlet 2.5

specification terms this the "error page mechanism", and describes how HTTP error codes or uncaught exception types can be mapped to error handling resources – either static HTML pages, or dynamic resources (JSPs or servlets). This mechanism is very declarative in nature, and is driven by the

the fully qualified class name of the exception (such as java.lang.Throwable); the error code is specified as an HTTP status error code (such as a 404 or a 500); and the location is specified as a URL. If the resource is a dynamic resource (such as a JSP or a servlet), the container will also make available to it, the request and response objects. It will also stuff in additional request attributes that will help the dynamic resource determine the specific error condition. These request attributes include: · javax.servlet.error.status_code – the HTTP status code; · javax.servlet.error.exception – the specific exception thrown, as a java.lang.Throwable. You can use this exception to get its message, print its stack trace, etc. · javax.servlet.error.request_uri – the URI of the original request, whose processing led to this error. · javax.servlet.error.servlet_name – the logical name of the servlet in which the error occurred. This mechanism kicks in when an uncaught exception is propagated up to the container, or when sendError() is called on the response to send an error code in the 4xx or 5xx ranges. 2. MyFaces Error Handling Both Facelets and MyFaces themselves provide additional error handling support – and surface a stack trace, the component tree, and request para
