    My XSLT file is:

    <xsl:stylesheet version="2.0" xmlns:xsl="[http://www.w3.org/1999/XSL/Transform](http://www.w3.org/1999/XSL/T ransform)" xmlns:fib="java:loadbuildergui.views.XMLParser" xmlns:saxon="[http://icl.com/saxon](http://icl.com/saxon)" exclude-result-prefixes="fib saxon">

    <xsl:template match="/">

    <Root>
    <xsl:for-each select="Module/LoadBuilder/Configuration">
    <Config>

    <LoadPartnumber><xsl:value-of select="@loadPN"/></LoadPartnumber>
    <Targets><xsl:value-of select="@targets"/></Targets>
    <DataPartnumber><xsl:value-of select="@dataPN"/></DataPartnumber>
    <DataFileName><xsl:value-of select="@dataFileName"/></DataFileName>

    <SupportFileName><xsl:value-of select="@supportFileName"/></SupportFileName>
    <ExportFilePath><xsl:value-of select="@ExportFile"/></ExportFilePath>

    </Config>
    </xsl:for-each>
    </Root>
    </xsl:template>

    <xsl:template match="abb" <br="">xmlns:fib="java:loadbuildergui.views.XMLParser">
    <abb>
    <xsl:value-of select="fib:ambi()"/>
    </abb>
    </xsl:template>

    </xsl:stylesheet>

    I am just trying to invoke a static function called ambi() of class XMLParser.

    There are a number of possible reasons: the two most likely are not having
    Saxon-EE activated, and the class not being on the classpath. If you're
    running from the command line, please (a) set the -t and -TJ options, and (b)
    tell us what your command line looked like, and what the output was. If you're
    running from a Java API, please tell us which API and how you are invoking it.

    Hi Michael,

    I am trying to run this XSLT file from Eclipse editor as XSL Transformation
    and I have the class path updated for the java file which I am trying to
    invoke. But still no joy.

    Thanks,
    Arun

    I would suggest trying to get it running from the command line first. There
    are so many ways of getting things wrong in Eclipse, it's hard to disentangle
    the issues.

    Try extending the classpath to include (a) the directory containing your
    license key, and (b) the directory or JAR file containing your compiled
    extension function.

    I have included both the license key and the jar containing compiled
    extenstion function but still the license key is not getting recognized,
    getting the same error.

    My CLASSPATH is:
    .;C:\Program Files\Java\jre1.6.0_07\lib\ext\QTJava.zip;C:\eclipse\interview\Lo
    adBuilderGUI\classes\loadbuildergui\views\LoadBuilder.jar;C:\saxon\arun.jar;C:
    \saxon\saxon-license.lic;

    Not sure what is going wrong.

    Don't put your license file on the classpath; put the directory containing the
    license key on the classpath.

    Still no joy, getting same error No license file found - running with

    ERROR! The markdown supplied could not be parsed correctly. Did you forget to surround a code snippet with "~~~~"?

    Check the FAQ on license key problems here:  
      
    [http://www.saxonica.com/documentation/about/installationjava/licensefaq.xml](
    http://www.saxonica.com/documentation/about/installationjava/licensefaq.xml)  
      
    If the directory containing the license file is on the classpath, it works,
    and if it isn't, then it fails the way you have described, so the cause is
    pretty clear. The slightest spelling mistake in defining your classpath will
    cause the symptoms you are decribing. Just check it again until you find the
    mistake.

    And I noticed you didn't set the -t option as I suggested.

    I got it working now, there was a space in the name of the license key file
    "saxon-license .lic"
    This was the culprit.

    Thank you so much for your help Michael.
