<%@taglib prefix ="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>

2. <fmt:formatDate value="${project.creatDate }" pattern="yyyy-MM-dd" />

First import the tag
<%@taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt"%>
<input type="text" value="<fmt:formatDate value ="${viewKq.srq}" pattern="yyyy-Md" />"/>
value="${viewKq.srq}" EL expression takes the date value Pattern
