xsl-taglibs using FTP URL

Hi all

It appears as if the (Jakarta) xsl-taglibs have difficulty fetching data via
an FTP URL. Has anybody tried this, with JSP?

I use the http://jakarta.apache.org/taglibs/xsl-1.0 library
(jakarta-taglibs-xsl-20010727), with the xsl-examples.war file, Apache
1.3.14, and Tomcat 3.2.1, on WinNT4.0-SP6. I have the following JSP:

<?xml version="1.0" encoding="iso-8859-1"?>
<%@taglib uri="http://jakarta.apache.org/taglibs/xsl-1.0" prefix="xsltlib"
%>
<A>
    <B>
        <C>
            <D>text</D>
        </C>
        <xsltlib:apply xsl="change.xsl"
                    xml="ftp://user:passwd@xxxxxxxxx/dir/file.xml"/>
    </B>
</A>

When I try a local XML file, it all works fine.
When I try the FTP URL in MSIE, the XML file is accessible.
Still, using the URL fails in the JSP: Tomcat gives me an "Unsafe path"
message.
(See error dump below).

Help on how to XSLT an XML file via an FTP URL with JSP is greatly
appreciated.
