I have implemented a form in JSF with 10 components (combo box, text
boxes etc.). if any of the validation is failed in these components
then i want to clear the value of one particular component. e.g if
combo box is not selected then i want to clear one of the text boxes
Thanks in Advance

Run a PhaseListener which listens on beforephase of render response and sets the submitted values of all UIInput components to null.

But the code of phaseListener will execute on each and every request. i want to clear particular textbox on the single page not on all pages but at some validation error generated by another components

Just check if Iterator#hasNext() of FacesContext#getMessages() returns true and then change the component tree accordingly. If necessary also check the UIViewRoot#getViewId() if it matches the desired view.
