I had the same problem with the 0.20.1 release. Try using the actual cvs version. There it works!

Shkuro, I have tried to replicate your solution and I still get strange errors.

I downloaded Fop-0.20.1-src.tar.gz on 9/17/01. Is there something more recent? I only ask because my ridiculous company still hasn't restored our internet access since Nimda. I would also be happy if I could get render(dom) working when applied to a dynamically-generated DOM object. I can get it to work on a DOM generated from a file, but not on the same DOM generated from an XSLT transform. I'd rather not have to save my XSLT output to a temp file every time I want to generate a PDF document. I described this case thoroughly at the end of the 'Does render(dom) actually work?' thread. I combine this code with what I have above and render(dom) works fine: <<<>>> File foFile = new File(foFilename); StreamResult streamResult = new StreamResult(foFile); transformer.transform(xmlDomSource, streamResult); org.w3c.dom.Document foDoc = dBuilder.parse(foFilename); DOMSource foDomSource = new DOMSource(foDoc); ... driver.render(foDoc); <<<>>> But if I try it this way: <<<>>> DOMResult domResult = new DOMResult(); transformer.transform(xmlDomSource, domResult); org.w3c.dom.Document foOutDoc = (org.w3c.dom.Document)domResult.getNode(); ... driver.render(foOutDoc); <<<>>> I get this error: <<<>>> building formatting object tree setting up fonts java.lang.NullPointerException at java.util.Hashtable.get(Hashtable.java:320) at org.apache.fop.fo.FOTreeBuilder.startElement(FOTreeBuilder.java:191) at org.apache.fop.tools.DocumentReader.parse(DocumentReader.java:444) at org.apache.fop.apps.Driver.render(Driver.java:449) at FOtoPDF.applyFop(FOtoPDF.java:131) at FOtoPDF.main(FOtoPDF.java:41) <<<>>> I have verified that the content of the file-generated DOM object and the XSLT-generated DOM object are exactly the same. The only difference I could find was that the DocumentType.getName() method returned 'fo:root' for the file-generated DOM object whereas the entire DocumentType was null for the XSLT-generated DOM object. I also tried this third method (with XSLTInputHandler and TraxInputHandler): org.apache.fop.apps.XSLTInputHandler xsltIH = new org.apache.fop.apps.XSLTInputHandler (xmlFile, xsltFile); driver.render(xsltIH.getParser(), xsltIH.getInputSource()); And I get these errors: <<<>>> using SAX parser org.apache.xerces.parsers.SAXParser building formatting object tree setting up fonts WARNING: Unknown formatting object ^layout-master-set WARNING: Unknown formatting object ^simple-page-master WARNING: Unknown formatting object ^region-body WARNING: Unknown formatting object ^region-before WARNING: Unknown formatting object ^region-after WARNING: Unknown formatting object ^page-sequence WARNING: Unknown formatting object ^static-content WARNING: Unknown formatting object ^block WARNING: Unknown formatting object ^table WARNING: Unknown formatting object ^table-column WARNING: Unknown formatting object ^table-body WARNING: Unknown formatting object ^table-row WARNING: Unknown formatting object ^table-cell WARNING: Unknown formatting object ^page-number WARNING: Unknown formatting object ^flow Parsing of document complete, stopping renderer Initial heap size: 1818Kb Current heap size: 1875Kb Total memory used: 57Kb Memory use is indicative; no GC was performed These figures should not be used comparatively Total time used: 281ms Pages rendererd: 0 Parsing of document complete, stopping renderer Initial heap size: 1818Kb Current heap size: 1884Kb Total memory used: 66Kb Memory use is indicative; no GC was performed These figures should not be used comparatively Total time used: 343ms Pages rendererd: 0 org.apache.fop.apps.FOPException: / by zero at org.apache.fop.apps.Driver.render(Driver.java:429) at FOtoPDF.applyFop(FOtoPDF.java:158) at FOtoPDF.main(FOtoPDF.java:41) --------- javax.xml.transform.TransformerException: / by zero at org.apache.xalan.transformer.TrAXFilter.parse(TrAXFilter.java:137) at org.apache.fop.apps.Driver.render(Driver.java:424) at FOtoPDF.applyFop(FOtoPDF.java:158) at FOtoPDF.main(FOtoPDF.java:41) --------- javax.xml.transform.TransformerException: / by zero at org.apache.xalan.transformer.TransformerImpl.transformNode(TransformerImpl.j ava:1212) at org.apache.xalan.transformer.TransformerImpl.run(TransformerImpl.java:2894) at java.lang.Thread.run(Thread.java:484) --------- java.lang.ArithmeticException: / by zero at org.apache.fop.apps.StreamRenderer.stopRenderer(StreamRenderer.java:146) at org.apache.fop.fo.FOTreeBuilder.endDocument(FOTreeBuilder.java:173) at org.apache.xalan.transformer.ResultTreeHandler.endDocument(ResultTreeHandler .java:180) at org.apache.xalan.transformer.TransformerImpl.transformNode(TransformerImpl.j ava:1194) at org.apache.xalan.transformer.TransformerImpl.run(TransformerImpl.java:2894) at java.lang.Thread.run(Thread.java:484) <<<>>> It was suggested make sure the document URI is being given to FOP. How do I do this in 0.20.1? I also saw these two suggestions: 1. Misspelled the URI for the xmlns:fo attribute, or 2. Did not use the "fo:" prefix on the root element while the default namespace is not the XSL-FO namespace. Could either of them possibly apply to my situation? Here is my root element: <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format";> I'm wondering if there is something weird going on here with DOM level 2? Or possibly some namespace or URI issues? I admit I'm no XML guru. I really stuck my neck out to get us to use FOP on this project instead of Root River. I promise I'll send a big fruit basket to anyone who can provide with some code for either of these three solutions that actually works.
