jstl parse error: javax.servlet.jsp.JspTagException: Unrecognized object supplied as 'xml' attribute to parse

I have a valid string of xml on a jsp(portlet version 1) project.

I am trying to use jstl tags to parse through it. Included tag libs:

    <%@ page import="javax.portlet.*"%>
<%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>

Currently I set the string:

String activexml = (String)renderRequest.getPortletSession().getAttribute("activexml");

Then I set my attribute for the jsp page:

pageContext.setAttribute("activexml", activexml);

This is all working, here comes the error. When I go to set the xml to be parsed. The C tag is good, no error comes back there, but the x receives the error:

<c:set var="active-xml" scope="session" value="${activexml}"/>
<x:parse xml="${active-xml}" var="active"/>

javax.servlet.jsp.JspTagException: Unrecognized object supplied as 'xml' attribute to parse

I have local copies of standard.jar and jstl.jar in my project. Any help would be most appreciated, I think it is either my syntax, or I am missing some project setup jars or something.

Thanks in advance.

Your mistake is in the declared variable name.

<c:set var="active-xml" ... />

Like in Java, the hyphen is in EL interpreted as subtraction operator. The ${active-xml} will basically give you the result of ${active} minus ${xml}.

Use an underscore instead.

<c:set var="active_xml" ... />

Or, just love Java code conventions a bit more and use camel case.

<c:set var="activeXml" ... />

Or, just use the original value right away without copying it via <c:set>.

<x:parse xml="${activexml}" ... />
