Java EE (Java Enterprise Edition) General Discussion

Hi

I have a <h:commandButton> within my form. I tried attaching a javascript handler for 'onclick' event of the button.
In the javascript method, i validate a field in form and stop the form submission in the onclick.

But i am not able to do it. All times form is getting submitted.( i do not want to go for trinidad for client side form validations )
How can i achieve, to stop the form submission, if i use <h:commandButton>


Thanks
