Can someone explain to me why the following code results in the error: According to TLD or attribute directive in tag file, attribute value does not accept any expressions. It always breaks whenever I am trying to set the value dynamically for the parameter of the URL.

<%@ page contentType='text/html; charset=UTF-8' %> <%@ taglib prefix='s' uri='/struts-tags' %> <%@ taglib uri='http://java.sun.com/jsp/jstl/core' prefix='c' %>  <c:forEach var='v' items='${files}'>     ${v} <a href='<s:url action='DeleteFile'><s:param name='fileName' value='${v}' /></s:url>'>Delete</a><br /> </c:forEach>

I’m using Struts 2 and the latest version of Java. Any help would be appreciated.

  1. You are mixing JSTL tags (the foreach) and Struts tags (the s param). Although it is possible to make them work together, why get into trouble?

    Use the struts iterator tag and dump the foreach.

    See details at http://struts.apache.org/2.0.14/docs/iterator.html

    In theory everything that can be done with JSTL is possible with native struts 2 tags, so your application should probably not need JSTL at all.
