I have a radio button Yes/No. If user clicks 'No' I make the hidden text box visible. this textbox validation should trigger if it is empty. How to do this? if user pressed YES then the validation should not fire.

can this be done using struts validation.xml or I should stick to client side javascript?

You should be able to do this with a "validWhen" validation. See the heading "Conditionally Required Fields" in this link for more information.
