How can I replace newline characters using JSP and JSTL?

Question

I have a list of bean objects passed into my JSP page, and one of them is a comment field. This field may contain newlines, and I want to replace them with semicolons using

Answer 1

This solution is more elegant than your own solution which is setting the pagecontext attribute directly. You should use the <c:set> tag for this:

<%@ 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, "; ")}

BTW: ${fn:replace(data, "\n", ";")} does NOT work.

Answer 2

In the value while setting the var, press ENTER between the double quotes.

${fn:replace(data, newLineChar, ";")}
