Solution 1

Don't use Java in JSPs, please. That's what the standard tag library is for.

<%@ 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>

In more detail:

Embedding Java code in a JSP makes the page difficult to read (JSP is a tag-oriented language), difficult to maintain, and difficult to debug.
The standard tag libraries are already debugged, have plentiful documentation and examples, and probably already Do What You Want To Do.
If you truly have some logic that needs to be performed in Java and no pre-existing tags exist, you can either a) put the logic in a bean and call it via JSTL or b) write your own tag using tagfiles.

Why is Java code better in a bean or tag library than in a JSP?

Testing is a big factor: beans and tag libraries can be tested outside of a running servlet environment with ease.
Tag libraries are reusable and significantly cleaner than JSP includes.

Make sure all your quotes are straight quotes, not curvy ones.

Solution 3

I guess you have copy pasted it from somewhere, make sure the double quotes are proper. I had the same issue when I copied it from a PDF, it was resolved once I corrected my double quotes.

Solution 4

Your JSP works just fine with Tomcat 6. So, it's probably either some include-related issue or some previously compiled classes are not getting recompiled.

Try to clean up your Tomcat work directory and try again.

Solution 5

Check " if you copied it from somewhere. I had the same error because of ".

<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> <%@page isELIgnored=”false” %>

double quotes around the false are the wrong ones. Change it to " and it will work.
