To use bean validation for form fields in JSF 2, you can use annotations in the bean like @Length(max=5).
However, since these constraints are already defined in my Hibernate entity object, for example: @Column(name = "FIELDX", length = 5), I was wondering if there's a way to use them for the validation?

No, you can't. And you shouldn't, because:
- validation logic might change while field definition is retained
- only a few of the constraints can be mapped to column definitions
