Richard Zowalla resolved TOMEE-2113.
------------------------------------
    Resolution: Auto Closed

Hi there!

We wanted to reach out and let you know that we're currently working on cleaning up open issues in Jira that specifically impact unsupported versions, including 1.7.x, 7.0.x, and 7.1.x.

If you had previously reported this issue on one of these unsupported versions, we kindly ask you to check if the problem still persists and can be reproduced on a supported version such as 8.0.x or 9.0.x. If you find that it is indeed reproducible on a supported version, you're more than welcome to re-open this issue.

Thanks!

>             Project: TomEE
>          Issue Type: Bug
>          Components: TomEE Core Server
>    Affects Versions: 7.0.4
>            Reporter: Katya Todorova
>            Priority: Major

> Tomee 7.0.4 replaces openejb-jstl.jar with apache taglibs.* (version 1.2.5). 
> Apache taglibs depend strongly on xalan for some tags implementation (e.g. set, forEach, when, ...) in a way that if xalan is missing on the classpath, there's no fallback to default jdk implementation but rather a ClassNotFoundException. According to release notes, this is implemented in the very first release ([1.2.0|https://tomcat.apache.org/taglibs/CHANGES.txt]) 
> Openejb-jstl (that packs javax.servlet.jstl 1.2) doesn't require xalan but apparantly has performance  impact (TOMEE-1066)
> The affected tags are not some side functionality but part of JSTL 1.2 specification (Section 11.1.5) so currently TomEE 7.0.4 is not compliant with JSTL 1.2 as it was in 7.0.3
> Here's an example jsp to reproduce the problem:
> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
> <%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml" %> 
> <html>  
> <body>
>     <x:parse var="cat">
>         <a>text</a>
>     </x:parse>
>     <x:set var="myVar" select="$cat//a"/> 	
>    </body>
> </html>  
> And the exception:
> java.lang.ClassNotFoundException: org.apache.xpath.XPath
