Cannot find a matching 0-argument function

[Arun]

Hi,

I am trying to invoke an external java function using Xslt and iam getting the
error:

---

Start Transformation (Mon Feb 06 23:46:55 CET 2012)
Error at xsl:value-of on line 35 column 42 of load_builder_template.xsl:
XPST0017: XPath syntax error at char 10 on line 35 in {fib:ambi()}:
Cannot find a matching 0-argument function named
{java:loadbuildergui.views.XMLParser}ambi()
Failed to compile stylesheet. 1 error detected.
--- End Transformation (Mon Feb 06 23:46:55 CET 2012) ---
-----------------------------------------------------------

I tried updating to latest saxon EE edition as well, but still getting the
same error.
Can any one help me out please?

Thanks,
Arun

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>
<SupportPartnumber><xsl:value-of select="@supportPN"/></SupportPartnumber>

</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

[Michael Kay]

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.

Hi Michael,

As suggested I tried from command line and I am getting below error. I am
using EE edition with trial license key.Can't i invoke external functions via
trial license key?

[Michael Kay]

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.

[Arun]

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.

[Michael Kay]

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

[Arun]

Still no joy, getting same error No license file found - running with
licensable features disabled.

[Michael Kay]

Check the FAQ on license key problems here:

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.

[Michael Kay]

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

[Arun]

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.
