  `@NotBlank`:: Checks that the annotated character sequence is not null and the trimmed length is greater than 0. The difference to `@NotEmpty` is that this constraint can only be applied on strings and that trailing white-spaces are ignored.  Is *deprecated* in favor of corresponding Bean Validation annotation (see <<validator-defineconstraints-spec>>).

  	Hibernate metadata impact::: None
  
  `@NotEmpty`:: Checks whether the annotated element is not null nor empty.  Is *deprecated* in favor of corresponding Bean Validation annotation (see <<validator-defineconstraints-spec>>).
