validation - Accept only digits for h:inputText value

Is there a way to confirm the value of an h:inputText in JSF, which should accepts only digits. Means it can be an Integer or the float.

If I type 12s3a562.675 , a5678s12 , 68712haf.563345 or any other such kind of values, then it should show an error. Otherwise it accepts and proceeds.

<h:inputText onkeypress="if(event.which &lt; 48 || event.which &gt; 57) return false;"/> is a short way if you want to accept integers only.

It has the advantage over type="number" that you can't even enter a non-digit
