[FIXED] Value is not printed on JSP page

Issue

model.addAttribute("error",ErrorMessages.USERLOGINERROR);

is not working while using redirect

return "redirect:/userlogin";

I have google it but not found approciate answer

if(name.equals("false")){
System.out.println(ErrorMessages.USERLOGINERROR);
model.addAttribute("error",ErrorMessages.USERLOGINERROR);
return "redirect:/getuserloginpage";
}

JSP:

<form:form action="userlogin" method="post" commandname="login">
<div align="center" style="color: red">${error}</div>
<div align="center" style="color: red">${thanks}</div>
...

expected result should be :

Please check your email or password. actual results : printed nothing. (no error or exception found)

Solution

Do one thing, you are using

return "redirect:/userlogin";

it means you have

@RequestMapping(value="/userlogin", method=GET)
public String yourMethod(Model model)
{
 your code.....
 return some_page_name;// from tiles.xml or directly as per you configuration
}

now use the same return

if(name.equals("false")){
System.out.println(ErrorMessages.USERLOGINERROR);
model.addAttribute("error",ErrorMessages.USERLOGINERROR);
//return "redirect:/getuserloginpage";
return some_page_name;  // simple and easy but take care of functionality
}
