Passing parameters to a template, with xsltc?

Hi!
Does parameter passing in a template supported with xsltc?

Here is a simple stylesheet: -- <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns="http://www.w3.org/1999/xhtml";> <xsl:template match="/"> Hello world!

                <xsl:call-template name="test">
                        <xsl:with-param name="param1">mblelop</xsl:with-param>
                </xsl:call-template>
        </xsl:template>

        <xsl:template name="test">
                <xsl:param name="param1"/>

                param1 = <xsl:value-of select="$param1"/>
        </xsl:template>
</xsl:stylesheet>

--

Now is here a program that makes use of it:

--
                new EnvironmentCheck().checkEnvironment(new 
PrintWriter(System.out));


            File xmlSourceFile = new File("test.xml");
                Source xmlSource = new StreamSource(xmlSourceFile);

File xsltFile = new File("test.xslt"); DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance(); documentBuilderFactory.setNamespaceAware(true); DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder(); Document xsltDocument = documentBuilder.parse(xsltFile); DOMSource xsltDOMSource = new DOMSource(xsltDocument);


            TransformerFactory transformerFactory = 
TransformerFactory.newInstance();
                Templates template = 
transformerFactory.newTemplates(xsltDOMSource);


            Result outResult = new StreamResult(System.out);
                template.newTransformer().transform(xmlSource, outResult);

Here is the result of this program:

-- #---- BEGIN writeEnvironmentReport($Revision: 1.23 $): Useful stuff found: ---- version.DOM.draftlevel=2.0fd java.class.path=webapps\blorp\WEB-INF\classes version.JAXP=1.1 or higher java.ext.dirs=C:\Program Files\Java\j2re1.4.2_03\lib\ext #---- BEGIN Listing XML-related jars in: foundclasses.sun.boot.class.path ---- xalan.jar-path=C:\j2sdk1.4.2_03\lib\endorsed\xalan.jar xml-apis.jar-apparent.version=xml-apis.jar present-unknown-version xml-apis.jar-path=C:\j2sdk1.4.2_03\lib\endorsed\xml-apis.jar xercesImpl.jar-apparent.version=xercesImpl.jar from xerces-2_4 xercesImpl.jar-path=C:\j2sdk1.4.2_03\lib\endorsed\xercesImpl.jar #----- END Listing XML-related jars in: foundclasses.sun.boot.class.path ----- version.xerces2=Xerces-J 2.4.0 version.xerces1=not-present version.xalan2_2=Xalan Java 2.5.2 version.xalan1=not-present version.ant=not-present java.version=1.4.2_03 version.DOM=2.0 version.crimson=present-unknown-version sun.boot.class.path=C:\j2sdk1.4.2_03\lib\endorsed\xalan.jar;C:\j2sdk1.4.2_03\lib \endorsed\xml-apis.jar;C:\j2sdk1.4.2_03\lib\endorsed\xercesImpl.jar;C:\Program F iles\Java\j2re1.4.2_03\lib\rt.jar;C:\Program Files\Java\j2re1.4.2_03\lib\i18n.ja r;C:\Program Files\Java\j2re1.4.2_03\lib\sunrsasign.jar;C:\Program Files\Java\j2 re1.4.2_03\lib\jsse.jar;C:\Program Files\Java\j2re1.4.2_03\lib\jce.jar;C:\Progra m Files\Java\j2re1.4.2_03\lib\charsets.jar;C:\Program Files\Java\j2re1.4.2_03\cl asses version.SAX=2.0 version.xalan2x=Xalan Java 2.5.2 #----- END writeEnvironmentReport: Useful properties found: ----- # YAHOO!

                Hello world!

                param1 = mblelop

As you can see, it works fine.

Now I add the system property to use xltc in my program:

                        String key = "javax.xml.transform.TransformerFactory";
                        String value = 
"org.apache.xalan.xsltc.trax.TransformerFactoryImpl";
                        Properties props = System.getProperties();
                        props.put(key, value);
                        System.setProperties(props);

And here is the new result: -- #---- BEGIN writeEnvironmentReport($Revision: 1.23 $): Useful stuff found: ---- version.DOM.draftlevel=2.0fd java.class.path=webapps\blorp\WEB-INF\classes version.JAXP=1.1 or higher java.ext.dirs=C:\Program Files\Java\j2re1.4.2_03\lib\ext #---- BEGIN Listing XML-related jars in: foundclasses.sun.boot.class.path ---- xalan.jar-path=C:\j2sdk1.4.2_03\lib\endorsed\xalan.jar xml-apis.jar-apparent.version=xml-apis.jar present-unknown-version xml-apis.jar-path=C:\j2sdk1.4.2_03\lib\endorsed\xml-apis.jar xercesImpl.jar-apparent.version=xercesImpl.jar from xerces-2_4 xercesImpl.jar-path=C:\j2sdk1.4.2_03\lib\endorsed\xercesImpl.jar #----- END Listing XML-related jars in: foundclasses.sun.boot.class.path ----- version.xerces2=Xerces-J 2.4.0 version.xerces1=not-present version.xalan2_2=Xalan Java 2.5.2 version.xalan1=not-present version.ant=not-present java.version=1.4.2_03 version.DOM=2.0 version.crimson=present-unknown-version sun.boot.class.path=C:\j2sdk1.4.2_03\lib\endorsed\xalan.jar;C:\j2sdk1.4.2_03\lib \endorsed\xml-apis.jar;C:\j2sdk1.4.2_03\lib\endorsed\xercesImpl.jar;C:\Program F iles\Java\j2re1.4.2_03\lib\rt.jar;C:\Program Files\Java\j2re1.4.2_03\lib\i18n.ja r;C:\Program Files\Java\j2re1.4.2_03\lib\sunrsasign.jar;C:\Program Files\Java\j2 re1.4.2_03\lib\jsse.jar;C:\Program Files\Java\j2re1.4.2_03\lib\jce.jar;C:\Progra m Files\Java\j2re1.4.2_03\lib\charsets.jar;C:\Program Files\Java\j2re1.4.2_03\cl asses version.SAX=2.0 version.xalan2x=Xalan Java 2.5.2 #----- END writeEnvironmentReport: Useful properties found: ----- # YAHOO!

                Hello world!

                param1 =
--

As you can see, the value of param1 has been lost!
Is it a normal thing, or a bug?

Thank you very much for your help.
