Answer / suresh
We can do it, There are two validation is available
1. Form validation
2. Server side validation
1. Form Validation - This validation is perform client side,
java script used to achieve these form validation
2. Server side Validation - This type we can use predefined
server side validation method used to achieve these validate.
Note:- In perform wise we compare Form validation is better
than server side validation. it's easy to progress.

If you want to intercept a request before servicing you
should use Filter concept in servlet which will help in
lots of ways. like the following...
1) Using the Filter we can logs the IPAddress of client
machine in log file.
2) can do the form validation like trim() functions.
