That "file:G:/Working..." is not a value being passed in... it's
something generated by either ANT or the XSLT processor... that's
stating the file where the exception is being caused.

I have had this all work, when I use the command line
org.apache.xalan.xslt.Process class.

I don't know if this will help much... but
a swath of my Ant target is this:

	<target name="xml2enum" depends="init">
                <delete dir="${temp.dir}"/>
		<style basedir="meta" 
                       destdir="${temp.dir}" 
                       extension=".enum" 
                       processor="trax" 
                       style="xslt/XML2ENUM.xslt" 
                       includes="xml/*.xml"/>
	</target>


the section in my xslt where it fails is this:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0"
    xmlns:lxslt="http://xml.apache.org/xslt"
    xmlns:redirect="org.apache.xalan.xslt.extensions.Redirect"
    extension-element-prefixes="redirect"> 

......

<xsl:template match="ServiceSystemSpecification">
  <xsl:for-each select="DataType/Enumeration">
      <xsl:variable name="fileName" select="concat(./@name,  '.java')"/>
      <xsl:variable name="fullpath" select="concat($outputDir,
'/Java/Enumeration/', $fileName)"/>
      <xsl:text>Created </xsl:text><xsl:value-of
select="$fullpath"/><xsl:text>
</xsl:text>
      <redirect:write select="$fullpath">
	<xsl:text>Something </xsl:text><xsl:value-of select="$fullpath"/>
        <xsl:call-template
name="JAVAGeneratedFileHeader"></xsl:call-template>  
        <xsl:call-template name="XML2ENUM"/>
      </redirect:write>
  </xsl:for-each>
</xsl:template>

The XML file is a big file... and probably not needed to figure out what
is wrong... because the actual
execution against the XML is working fine...  it's when it hits that
<redirect:write> that it coughs
up on.


I can switch the processor attribute in the ANT file from "trax" to
"xalan" and everything works fine.

When it is in "trax" mode... this is the error I get after it tries to
apply the stylesheet:

xml2enum:
   [delete] Deleting directory G:\Working\main\echo\temp
    [style] Transforming into G:\Working\main\echo\temp
    [style] Loading stylesheet
G:\Working\main\echo\meta\xslt\XML2ENUM.xslt
    [style] Transforming into G:\Working\main\echo\temp
file:G:/Working/main/echo/meta/xslt/XML2ENUM.xslt; Line 25; Column
42;     [styl
e] Failed to process
G:\Working\main\echo\meta\xml\IIMS_INTERNAL_META.xml

BUILD FAILED

G:\WORKING\main\echo\build.xml:391:
javax.xml.transform.TransformerException


The Line 25; Column 42; is the end of the line where the REDIRECT
command is found.  The IIMS_INTERNAL_META.xml is the XML file that is
being processed.


Now... I know the new XALAN 2.x also has XSLTC stuff inside of it. 
However, theoretically... you need to somehow explicitly state that you
want to use it for your transformations for the TRaX stuff to use it. 
And I know from the Release Notes... XSLTC doesn't support REDIRECT. 
But TRaX IS SUPPOSE to support it.
Is somehow XSLTC being used for the transformations instead of just pure
TRaX???

All this stuff isn't working on my and another colleague's PC machine. 
However, another guy has it running fine on a Linux-box.


Thanks!
