Looks too convolute to me. If you have already created pdf file on a disk, why 
  do you process it by hands instead of rely on a web server? Just redirect 
browser to the file, that will emulate reading static pdf, which works okay 
even in IE (well, at least if extension is pdf).
I mean
response.sendRedirect("/foo/bar.pdf");

It's not FOP, its the XSLT processor.
Use
  <rect height="50" width="1.5" x="{$x}" y="0.0"/>

This is called "attribute value template", look up details in
an XSLT book, a tutorial or the XSL FAQ.

XSLT questions like this are better asked on the XSL list:

Hi

this is my code for genrate code barre from a  number

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:svg="http://www.w3.org/Graphics/SVG/SVG-19990812.dtd">
 <xsl:template name="codebarre">
  <xsl:variable name="index" select="string-length(codebarre)"/>
  <xsl:variable name="x"/>

  <xsl:param name="i" select="0"/>

  <xsl:if test="$i &lt; $index">
   <xsl:choose>
    <xsl:when test="substring(codebarre,$i+1,1)='1'">
     <svg xmlns="http://www.w3.org/2000/svg">
      <rect height="50" width="4.0" x="$x" y="0.0"/>
     </svg>
     <xsl:variable name="x" select="$x+4"/>
     <fo:block>large noir</fo:block>
    </xsl:when>
    <xsl:when test="substring(codebarre,$i+1,1)='2'">
     <svg xmlns="http://www.w3.org/2000/svg">
      <rect height="50" width="1.5" x="$x" y="0.0"/>
     </svg>
     <xsl:variable name="x" select="$x+1.5"/>
    </xsl:when>
    <xsl:when test="substring(codebarre,$i+1,1)='3'">
     <xsl:variable name="x" select="$x+3"/>
    </xsl:when>
    <xsl:when test="substring(codebarre,$i+1,1)='4'">
     <xsl:variable name="x" select="$x+1.5"/>
    </xsl:when>
   </xsl:choose>

   <xsl:call-template name="codebarre">
    <xsl:with-param name="i" select="$i+1"/>
   </xsl:call-template>

  </xsl:if>
 </xsl:template>
</xsl:stylesheet>

but fop doesn't want assign the value of $x in "rec" tag

any ideas ??
