After running application, jsf works, in my mysql it creates two tables as I wanted, but I can't save any users no matter how many i add new user from my web application, it doesn't work.

You need to link Spring and JSF together. There's a reference you can put in the faces-config application element that allows the JSF EL processor to see Spring beans, making them inectable into JSF managed beans. I can't recall the name - they recently changed it. However, the older mechanism looked like this:

	<application>
		<variable-resolver>
			org.springframework.web.jsf.DelegatingVariableResolver</variable-resolver>
      </application>
