Bug ID: 60950
Summary: JSTL TransformSupport XSL import not finding relative
path
Product: Taglibs
Version: 1.2.5
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: XTags Taglib

Reproducer war
When you try to use references to local xslt files inside same deployment.
You can get error when creating XML Transformer as transformer factory doesn't
have URI resolver set to be able to recognize jstl protocol.
Reproducer "test.war" is attached.
Part of code that makes it fail:
test.jsp:
------------
<c:import var="xslStylesheet" url="/xsl/style.xsl" charEncoding="UTF-8" />
<c:import url="http://localhost:8080/test/test.xml"; var="doc"/>
<x:transform xml="${doc}" xslt="${xslStylesheet}" xsltSystemId="/xsl/">
</x:transform>
style.xsl
---------------
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
version="1.0">
<xsl:import href="parent.xsl"/>
...
results in
javax.xml.transform.TransformerException: Had IO Exception with stylesheet
file: parent.xsl
