How can I replace newline characters using JSP and JSTL?

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
<% pageContext.setAttribute("newLineChar", "n"); %>

${fn:replace(item.comments, newLineChar, "; ")}

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>

<c:set var="newline" value="n"/>
${fn:replace(data, newLine, "; ")}
