Re: hot to pass objects to include page

One way to do it with JSTL is to use jsp includes, then just include the 
  "component" wherever you want to use it.  Other than that, I think you 
have to make an component class and drop jstl for that component.  Then 
you could just plug in that componenent with <c:out 
value="${myComponent.display}"/>
