Saxon

Hi,

I've been using Xalan xslt processor before so I'm used to use the java function this way: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:java="xalan://java.util.Math" version="1.0">

Or any java function I wrote: xmlns:myfn="xalan://com.mycompany.myproduct.Utils

But when I tried to use saxon, from the research I've done, it seems that all I need is this: xmlns:myfnb="java:com.mycompany.myproduct.Utils"

and I should be able to use any methods in Utils class.

But the fact is that, when I tried this with Saxon-HE, I got the following error message:

Error on line 5 of foo.xsl: XTDE1425: Cannot find a matching 0-argument function named {java.util.Math}random(). For diagnostics on calls to Java methods, use the -TJ command line option or set the Configuration property FeatureKeys.TRACE_EXTERNAL_FUNCTIONS in built-in template rule ; SystemID: file:/C:/foo.xsl; Line#: 5; Column#: -1 net.sf.saxon.trans.XPathException: Cannot find a matching 0-argument function named {java.util.Math}random(). For diagnostics on calls to Java methods, use the -TJ command line option or set the Configuration property FeatureKeys.TRACE_EXTERNAL_FUNCTIONS at net.sf.saxon.expr.ErrorExpression.evaluateItem(ErrorExpression.java:66) at net.sf.saxon.expr.ErrorExpression.iterate(ErrorExpression.java:80) ...

My simple foo.xsl is like this:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:math="java.util.Math" version="1.0"> <xsl:template match="doc"> <xsl:value-of select="."/>

<xsl:value-of select="math:random()"/>

My simple transformer java class is like this:

public static void main(String[] args) {

    File xsltFile = new File("C:/foo.xsl");
    File xmlFile = new File("C:/foo.xml");
    File resultFile = new File("C:/result.xml");

    try {
  
        Source xmlSource = new StreamSource(xmlFile);
        Source xsltSource = new StreamSource(xsltFile);
        
        Processor proc = new Processor(false);
        XsltCompiler comp = proc.newXsltCompiler();
        XsltExecutable exp = comp.compile(xsltSource);
        XdmNode source = proc.newDocumentBuilder().build(xmlSource);
        Serializer out = new Serializer();
        out.setOutputProperty(Serializer.Property.METHOD, "xml");
        out.setOutputProperty(Serializer.Property.INDENT, "yes");
        out.setOutputFile(resultFile);
        XsltTransformer trans = exp.load();
        trans.setInitialContextNode(source);
        trans.setDestination(out);
        QName paramName = new QName("IMBOutgoingBarcode");
        trans.setParameter(paramName, new XdmAtomicValue("45678"));
        trans.transform();
       
    } catch (Exception e ) {
    	e.printStackTrace();
    }

}

I believe that it should be an easy task to perform the java function call. But maybe I haven't found the right documentation to look for.

Thanks for the help.
