either inside the page or outside the page (such as in a called JavaBean). This section describes the JSP error processing mechanism and provides a simple example. Using JSP Error Pages Any runtime error encountered during execution of a JSP page is error page in jsp example handled using the standard Java exception mechanism in one of two ways: You can jsp error handling and debugging catch and handle exceptions in a Java scriptlet within the JSP page itself, using standard Java exception-handling code. Exceptions you do not jsp error page tag 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 http://www.tutorialspoint.com/jsp/jsp_exception_handling.htm 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 occuring in your JSP code. Using Exception Object: The exception object is an instance of a subclass of Throwable (e.g., java.lang. NullPointerException) and is only available in error pages. Following is the list of important medthods available in the Throwable class. SNMethods with Description 1public String getMessage()
Returns a detailed message about the exception that has occurred. This message is initialized in the Throwable constructor. 2public Throwable getCause() Returns the cause of the exception as represented by a Throwable object. 3pub▼ JSP Tutorial JSP Introduction Life cycle of JSP JSP API JSP in Eclipse JSP scripting elements JSP scriptlet tag JSP expression tag JSP http://www.javatpoint.com/exception-handling-in-jsp declaration tag 9 Implicit Objects JSP Request JSP Response JSP Config JSP Application JSP Session JSP PageContext JSP Page JSP Exception JSP Directive Elements JSP page directive JSP include directive JSP taglib directive JSP Exception Action Elements jsp:forward jsp:include Java Bean class jsp:useBean set & getProperty Displaying applet in JSP Expression Language MVC in JSP JSTL JSP Custom error page tags Example of Custom Tag Attributes Iteration Custom URI JSP Pagination JSP Pagination Example JSP CRUD JSP CRUD Example Development in JSP Registration Form Login Form Uploading File Downloading File Interview Questions JSP Quiz next>> <
