In Struts 1
Form data can be validated on the client side as well as on the server side using the Validator Framework,
which was developed as a third-party add on to Struts. This framework generates the java script and it can be
used to validate the form data on the client browser. Server side validation of your form can be carried out by
subclassing your form class with DynaValidatorForm class. The Validator Framework uses 2 xml configuration
files validator-rules.xml (defines reusable standard validation routines, which are usable in validator.xml) and
validator.xml (defines validation applicable to a form bean).
Take up one idea. Make that one idea your life; dream of it; think of it; live on that idea. Let the brain, the body, muscles, nerves, every part of your body be full of that idea, and just leave every other idea alone. This is the way to success.
