title: hibernate / spring validation in service layer
body: <p>---added (edit) --</p>
  
  <p>should you do validation at the service layer, even if you validate at the front-end?</p>
  
  <p>eg struts has validations so you can validate it a lot. (I don't mean java script validations.)</p>
  
  <p>--</p>
  
  <p>are you using hibernate validator or spring validations in your service layer even though you have validations already on front-end? </p>
  
  <p>(front-end validation don't have to be hibernate or spring one)</p>
