java - How to get an item

Question

JSP tag code is:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ attribute name="items" required="true" %>
${items[0]}

JSP code is:

<%@ taglib prefix="t" tagdir="/WEB-INF/tags"%>
<t:input items="${form.items}"></t:input>

Maybe I forgot type of the attribute or something else? Why is the way to access values different in JSP and JSP tag?

The default type of attributes is java.lang.String. If you expect something else, specify the expected type:

<%@ attribute name="items" required="java.util.Collection" %>

or

<%@ attribute name="items" required="java.lang.Object" %>

for example.
