How to Design Spring MVC for View Page
How to access the bean values where the bean has sub bean
class Student
{
String Name;
Address houseAddress;
.
.
}
For accessing values in Student bean the form elements should be
path=Name value="${student.Name}"
For accessing values in Student Address bean the form elements should be
path=Address.houseAddress value="${Student.Address.StreetName}"

Method Arguments in Controller
@Controller
@RequestMapping("/Control1")
public class TestController
{
@RequestMapping("/Control2")
public String TestMe(HttpSession session, HttpServletRequest request)
{
request.setAttribute("name", "Mugil Vannan");
session.setAttribute("Test", "TestValue");
System.out.println("1");
return "hello";
}
@RequestMapping(value="/Control2", method=RequestMethod.POST)
public String TestMe2(HttpSession session, HttpServletRequest request)
{
System.out.println(session.getAttribute("Test"));
System.out.println(request.getParameter("cboArea"));
return "display";
}
}
Alternate of HttpServletRequest request
@RequestMapping(value="/Control2", method=RequestMethod.POST)
public String TestMe2(HttpSession session, @RequestParam("cboArea") String Area)
{
System.out.println(session.getAttribute("Test"));
System.out.println(Area);
return "display";
}
