To test my class i've used xml2pdf.xsl and xslfoRef.xml but u got the following exception :   [ERROR] Unknown formatting object ^root org.apache.fop.apps.FOPException: Root element must be root, not (none):root  at org.apache.fop.fo.FOTreeBuilder.startElement(Unknown Source)  at org.apache.xerces.parsers.AbstractSAXParser.startElement(AbstractSAXParser.java:434)  at org.apache.xerces.impl.XMLNamespaceBinder.handleStartElement(XMLNamespaceBinder.java:832)  at org.apache.xerces.impl.XMLNamespaceBinder.startElement(XMLNamespaceBinder.java:568)  at org.apache.xerces.impl.dtd.XMLDTDValidator.startElement(XMLDTDValidator.java:796)  at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanStartElement(XMLDocumentFragmentScannerImpl.java:752)  at org.apache.xerces.impl.XMLDocumentScannerImpl$ContentDispatcher.scanRootElementHook(XMLDocumentScannerImpl.java:927) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(XMLDocumentFragmentScannerImpl.java:1519)  at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:333)  at org.apache.xerces.parsers.StandardParserConfiguration.parse(StandardParserConfiguration.java:529)  at org.apache.xerces.parsers.StandardParserConfiguration.parse(StandardParserConfiguration.java:585)  at org.apache.xerces.parsers.XMLParser.parse(XMLParser.java:147)  at org.apache.xerces.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1148)  at org.apache.fop.apps.Driver.render(Unknown Source)  at com.isyde.testfop.CreatePdf.renderXML(CreatePdf.java:118)  at com.isyde.testfop.CreatePdf.<init>(CreatePdf.java:61)  at com.isyde.testfop.CreatePdf.main(CreatePdf.java:161)   Exception in thread "main"   Can You help me?   Many Thanks!   Paolo B.
