Exception while using embedded example

[Deri Cronin <de...@camelotinteractive.com>]

I am evaluating the FOP servlet for use on a website. 

Any suggestions how to make this work?

1) Using the embedded example servlet running in Tomcat4.0. Calling the
servlet with the glossary.xml and glossary.xsl from the download will create
a PDF correctly but the servlet response is not built correctly.

2) When running in Tomcat3.2 the I get the following exception: -

The message states "Names space not supported by SAX parser"


This is the code: -

public class XSLTInputHandler extends InputHandler {

//...

    public XMLReader getParser() throws FOPException {
	XMLReader xmlreader = null;
	try {
	    Class var_class =
Class.forName("javax.xml.transform.Transformer");
	    var_class =
Class.forName("org.apache.fop.apps.TraxInputHandler");
	    Class[] var_classes = { File.class, File.class };
	    Method method = var_class.getMethod("getXMLFilter",
var_classes);
	    File[] files = { xmlfile, xsltfile };

//	this call throws an InvocationTargetException 
	    Object object = method.invoke(null, files);

	    if (object instanceof XMLReader)
		xmlreader = (XMLReader) object;
	} catch (ClassNotFoundException classnotfoundexception) {
	    throw new FOPException(classnotfoundexception);
	} catch (InvocationTargetException invocationtargetexception) {
	    throw new FOPException(invocationtargetexception);
	} catch (IllegalAccessException illegalaccessexception) {
	    throw new FOPException(illegalaccessexception);
	} catch (NoSuchMethodException nosuchmethodexception) {
	    throw new FOPException(nosuchmethodexception);
	}
	if (xmlreader == null) {
	    useOldTransform = true;
	    xmlreader = InputHandler.createParser();

What do you mean exactly, do you get empty page or broken pdf or exception?

This message usually means the found parser doesn't support sax2 api, look for 
old xerces etc in the tomcat classpath.
