Answer 1

You can pass data from controller to UI(another JSP page) with the help of ModelAndView in Spring.

new ModelAndView("newJSPPage","aliasNameToBean",originalBean);

newJSPPage - replace with the new JSP file which you need to redirect from the controller.

aliasNameToBean - replace with the alias name which you can access bean data at redirected JSP page.

originalBean - replace with the original bean object name which you have the data.

Answer 2

return "redirect:/EditShop.jsp";

Insted of this you have return View Name like return "EditShop";

In Spring Execution Flow InternalResourceViewResolver will Take Care to Call Jsp.

you have to set val to HttpSession Object like session.setAttribut("val",valueofField);

Then you get that value In your jsp session.getAttribute("val");

I Hope it helps.
