My code is :

StreamSource xmlDoc = new StreamSource(new FileInputStream("
catalog.xml"));

//TransformerFactory tFactory = TransformerFactory.newInstance

TransformerFactory tFactory= TransformerFactory.newInstance();
StreamSource stylesheet = new StreamSource(new FileInputStream("
style.xsl"));
Transformer transformer = tFactory.newTransformer(stylesheet);

StreamResult result = new StreamResult(new
FileOutputStream("C:/Reports1.xml"));

transformer.transform(xmlDoc,result);

Well I don't have much experience using Java and XML but it looks like you
are using XSLT 1.0 instead of version 2.0 so the stuff that's supposed to
tell it to use Saxon isn't working as you want.

my input xml is :

<xsl:stylesheet version="2.0" xmlns:xsl="
http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:template match="/technology">
<xsl:for-each-group select="/technology/CATALOG//CD" group-by="COUNTRY">
<xsl:sort select="COUNTRY"/>
<COUNTRY name="{COUNTRY}">
<xsl:for-each-group select="current-group()" group-by="YEAR">
<YEAR year="{YEAR}">
<xsl:copy-of select="current-group()/TITLE"/>
</YEAR>
</xsl:for-each-group>
</COUNTRY>
</xsl:for-each-group>
</xsl:template>
</xsl:stylesheet>

this xslt is 2.0 bcz for-each-group is new feature in xslt 2.0

See my response to your previous question - basically your using Xalan
which is an XSLT 1.0 processor and so doesn't understand XSLT 2.0's
current-group()

How can I tell you're using Xalan just from the stack trace? Because
if you look at the stack trace, it says "org.apache.xalan.processor" a
lot.

thnax fr u r reply Mr. Andrew Welch.

Ya u r correct that xalan is 1.0. although i am setting system property to
SAxon it will poiting to
xalan. moreover jdk internally contains xalan api. i have tried all means
such as directly using saxon
transformerfactoryimpl to create transformer. even though i am getting the
same exception.

k anywway thnx a ton for u r prompted response.

Make sure you use Saxon 8.9.0.4 which you can find here:
<http://sourceforge.net/project/showfiles.php?group_id=29872>
I think there was a problem in the early 8.9.0 releases so that JAXP
APIs don't work as they should.
