Sample Code

class UserForm {
    private String name;
    private String address;

    //setter and getter

}

In Your Controller

 @RequestMapper(value="/user")
    public ModelAndView user(){
        ModelAndView mav = new ModelAndView("userForm") ;
        List<UserForm> userForms = yourDatabaseCall();
        mav.addObject("userForms", userForms);  
        return mav;``
    }

in jsp page:

<c:forEach items="${userForms}" var="userForm">     
   <c:out value="${userForm.name}"/>
   <c:out value="${userForm.address}"/>
</c:forEach>

You can add list of userFomrs as a model attribute

List<UserForm> userForms = yourDatabaseCall();
model.addAttribute("userForms", userForms);     

In JSTL you can iterate over it

<c:forEach items="${userForms}" var="userForm">     
   // Do something
</c:forEach>
