XSLT2.0 in XMLTransform?

Brian_Harcourt · June 13, 2017, 6:57pm

I’m trying to move from CF10 to Lucee and find a way to get XMLTransform to work with some long running XSLT2.0.

I see that saxon he is not be default installed with Lucee (Lucee 5.2.1.9) so I found the OSGi at

and placed it in …/tomcat/lucee-server/bundles/. I now see Saxon in the admin page ‘info.bundle’ shown as ‘not loaded’.

And the stacktrace is still showing xalan.

Is there a way for me to get XMLTransform function to use Saxon? Or am I barking up the wrong tree?

I’ve tried setting the TransformerFactory in the JVM config . . .
No love

Brian_Harcourt · June 14, 2017, 1:30am

I’ve tried adding the JVM config to setenv.sh

CATALINA_OPTS="-Xms256m -Xmx512m -Djavax.xml.transform.TransformerFactory=net.sf.saxon.TransformerFactoryImpl";

Still no joy

I’m not sure I know enough about java but it looks to me like the

import org.apache.xalan.processor.TransformerFactoryImpl;

Unfortunately, I’m not much of a java coder so I’m not in a position to pull the XMLUtil.java; adjust it; compile it; and test it. But I still believe that the issue outlined above is the source of my difficulties. Instead I’ve simply re-written the native function to instantiate the saxon stuff inside the cfml environment I’m accustomed to. It’s moving me forward on transferring from CF10 to Lucee. I may revisit this issue when I have more time (teach myself some java).

Here’s what I’ve done - far from perfect and it’ll evolve as I go forward I’m sure - but it’s working at the moment:

public string function XMLTransform (xmlDoc, xslDoc) {
        try {   
                if (IsXmlNode(arguments.xmlDoc)) {
                        arguments.xmlDoc = arguments.xmlDoc.toString();
                }
                if (IsXmlNode(arguments.xslDoc)) {
                        arguments.xslDoc = arguments.xslDoc.toString();
                }
                if (FileExists(arguments.xslDoc)) {
                        arguments.xslDoc = FileRead(arguments.xslDoc);
                }
                xslReader = createObject('java','java.io.StringReader').init(arguments.xslDoc);
                xmlReader = createObject('java','java.io.StringReader').init(arguments.xmlDoc);
                stmXSL = createObject('java','javax.xml.transform.stream.StreamSource').init(xslReader);
                stmXML = createObject('java','javax.xml.transform.stream.StreamSource').init(xmlReader);
                proc = createObject('java','net.sf.saxon.s9api.Processor','org.apache.servicemix.bundles.saxon').init(false);
                dest = createObject('java','net.sf.saxon.s9api.XdmDestination').init();

                comp = proc.newXsltCompiler();
                exec = comp.compile(stmXSL);
                transformer = exec.load();
                transformer.setDestination(dest);

                builder = proc.newDocumentBuilder();
                builder.setLineNumbering(true);
                source = builder.build(stmXML);

                transformer.setInitialContextNode(source);
                
                transformer.transform();
        } catch (any e) {
                if (structKeyExists(request, 'stcErr')) {
                        request.stcErr.transArgs = arguments;
                        request.stcErr.catch = e;
                }
        }

        return dest.getXdmNode().toString();
}

Worth noting the saxon-he OSGi bundle posted above did NOT work even when working directly with the objects themselves. I’m not recalling what stopped me there. Instead I pulled from here:
