Data validation is all about what can be entered into a spreadsheet cell or database cell, you can choose an error message aswell as restricting what values can be entered, reducing human error and improving accuracy.

Validation is a form of self protecting; it is better to reject bad data then spend hours trying to find out an error only to discover that the problem was caused by a "user error". Checking to verify that appropriate values have been entered for the text box is called validation. The validation may include making sure that data is numeric, checking for specific values, checking a range of values, making sure that required data is entered.
In a database it is important that data is put in accurately. One method of doing that is to use validation rules to restrict what people can put in. So you might have a school where children have to be over a certain age before they can join. You could build a validation rule to ensure they meet that requirement or to ensure that the person entering the data does not make a mistake when entering it. A validation rule will stop them making an error and with the Validation Text, it will give them a message telling them what their error is.
Declare That a JSP Page Is an Error PageThe isErrorPage attribute tells the container if the current page is available to be an error page for another JSP page (the current page is the URL in another page's errorPage attribute). Ex:If this attribute is set to "true" then the variable "exception" is available to you. Otherwise (default is "false"), if you try to reference the exception, you will get a fatal error.So, when a Servlet request being forwarded to a JSP Page faces an exception/error this error page would get called.
