I'm trying to set a cookie value within a JSP without using Java code directly. I know I could do it by creating a custom tag lib for that, but I wanted to keep it simple so I'm trying to do that the same way I access cookies: with EL expressions.
I know I can read the value of a cookie using JSP EL with the expression ${cookie['cookieName'].value}
, but how can I set a particular value to that cookie using EL? I found solutions using java code in the JSP, but I want to avoid that.
So far I found ways to set variables using the c:set tag, but that doesn't accept expressions as the 'var' parameter so I can't do something like:
<c:set var="${cookie['cookieName'].value}" value="123" />
I think the way to go is , but I don't know what expression to use for the var part of it, or how to write it so I can set the cookie value instead of just a variable.
Any help is appreciated!
There is no standard expression to set cookie in JSP. You can use custom tag if you want OR use JSP script-less
<%
javax.servlet.http.Cookie cookie
= new javax.servlet.http.Cookie("name", "value");
// cookie.setXXX()
response.addCookie(cookie);
%>
NOTE: Make sure cookie is added BEFORE the response is committed.
