Retrieving cookie and array values in JSTL tags
java, jsp, jstl
Solution
The `${cookie}` points to a `Map<String, Cookie>` with the cookie name as map key and the `Cookie` object as map value. Every iteration over a `Map` in `<c:forEach>` gives you a `Map.Entry` back which in turn has `getKey()` and `getValue()` methods. Your confusion is that the `Cookie` object has in turn also a `getValue()` method.
<c:forEach items="${cookie}" var="currentCookie">
Cookie name as map entry key: ${currentCookie.key}<br/>
Cookie object as map entry value: ${currentCookie.value}<br/>
Name property of Cookie object: ${currentCookie.value.name}<br/>
Value property of Cookie object: ${currentCookie.value.value}<br/>
</c:forEach>
It's a `Map<String, Cookie>` because it allows you easy direct access to cookie value when you already know the name beforehand. The below example assumes it to be `cookieName`:
${cookie.cookieName.value}
Your list example is by the way invalid. The `var` should not refer the same name as the list itself.
Problem
While retrieving cookies I need to use: ``` <c:forEach items="${cookie}" var="currentCookie"> ${currentCookie.value.name} </br> </c:forEach> ``` But, while using custom arrays, why we need to skip the .value function? ``` <c:forEach items="${myList}" var="myList"> ${myList.name} </br> </c:forEach> ``` Cookie contains a .getValue function() which returns the content of the cookie in string format, so how does using currentCookie.value.name work?
