How to validate empty value which is double type in jsf?

Question

I have the jsf input text as double type in pojo class. I want to validate that field with empty check. By default in page load the value comes as 0.0 in the text field. Once I clear the value (i.e empty value) and click submit button, the text field is not getting validated.

Any help would be appreciated.

If you want it to appear empty than you can change from double (primitive) into Double (Object)

and set the field to required="true"
