["Kalra, Ashwani" <as...@capgemini.com>]

value in it. For example. I want to validate a field which should of type
int.But  it should be validated only if use has entered some value in it.

hi,

if you are validating in your form or action class you can check if the 
field is not empty (!= null or !equals("") and then check for correct 
int value.
