Do not use Java in JSP, please. This is what is for the standard tag library.
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<body>
<h1 align="center">blablalblalblab</h1>
<p>
<c:forEach items="${styles}" var="style">
<br>try: ${style}
</c:forEach>
</p>
</body>
</html>
More details:
- Embedding Java code in the JSP makes the page difficult to read (JSP is a tag-oriented language), which is difficult to maintain and difficult to debug.
