You can have following type of errors in your jsp error page example 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 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()

Exception Handling in JSP is much easier than Java Technology exception handling. Although JSP Technology also uses the same exception class objects. It is quite obvious that you dont want to show error stack trace to any random user surfing your website. You can't prevent all errors in your application but you can atleast give a user friendly error response page. Ways to perform Exception Handling in JSP JSP provide 3 different ways to perform exception handling: Using isErrorPage and errorPage attribute of page directive. Using
