Question

I have this situation where I am required to show where if user does not enter right password, the program will place an appropriate message in a session & will Dispatch back to the login jsp page and display the message.

I checked this one as well, Redirect to the same page but with a message in it

But when I try implement the answer, the eclipse gives me a red line over the code.

Here is my code,

String message = "Wrong Password!";

HttpSession session = session.setAttribute("message", message);

The error shown is Type Mismatch: Cannot Convert to from void to HttpSession

Any ideas where I am wrong or how can I do this?

Answer 1

session.setAttribute("message", message);

this return type is void, hence your pionting to HttpSessoin Object, so it is giving showing complier error.

Use this

HttpSession session = request.getSession(true);
session.setAttribute("message", message);
