change the date format in jsf

I've retrieved data from database and displayed it using

<h:column>
  <f:facet name="header">
   <h:outputText value=" Date"/>
  </f:facet>
  <h:outputText value="#{item.date}"></h:outputText>
</h:column>

the date here is displayed in YYYY-MM-DD, I want to change it to normal i.e., dd-mm-yyyy format.Can i get any suggestion??
