For some reason, the Squiggle in the Batik I have checked-out from SVN (and not updated for a few weeks) is giving an error opening certain SVG files. Neither Batik or the document have changed in the last few weeks and yet now when I try to open an SVG document that does not contain this line at the top:
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd";> I get this exception: org.apache.batik.dom.util.SAXIOException: Document is invalid: no grammar found. at org.apache.batik.dom.util.SAXDocumentFactory.createDocument(SAXDocumentFacto ry.java:445) at org.apache.batik.dom.util.SAXDocumentFactory.createDocument(SAXDocumentFacto ry.java:357) at org.apache.batik.dom.svg.SAXSVGDocumentFactory.createDocument(SAXSVGDocument Factory.java:201) at org.apache.batik.dom.svg.SAXSVGDocumentFactory.createSVGDocument(SAXSVGDocum entFactory.java:124) at org.apache.batik.bridge.DocumentLoader.loadDocument(DocumentLoader.java:106) at org.apache.batik.swing.svg.SVGDocumentLoader.run(SVGDocumentLoader.java:84) Caused by: org.xml.sax.SAXParseException: Document is invalid: no grammar found. at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseEx ception(ErrorHandlerWrapper.java:195) at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.error(ErrorHandl erWrapper.java:131) at com.sun.org.apache.xerces.internal.impl.XMLErrorReporter.reportError(XMLErro rReporter.java:384) at com.sun.org.apache.xerces.internal.impl.XMLErrorReporter.reportError(XMLErro rReporter.java:318) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.scanStartEl ement(XMLNSDocumentScannerImpl.java:250) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl$NSContentDr iver.scanRootElementHook(XMLNSDocumentScannerImpl.java:626) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$Fragm entContentDriver.next(XMLDocumentFragmentScannerImpl.java:3095) at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl$PrologDriver. next(XMLDocumentScannerImpl.java:921) at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.next(XMLDocum entScannerImpl.java:648) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.next(XMLNSD ocumentScannerImpl.java:140) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanD ocument(XMLDocumentFragmentScannerImpl.java:510) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Con figuration.java:807) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Con figuration.java:737) at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:10 7) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractS AXParser.java:1205) at org.apache.batik.dom.util.SAXDocumentFactory.createDocument(SAXDocumentFacto ry.java:439) ... 5 more If I add the omitted line then everything is fine again. But given that I used to be able to open SVG files containing nothing more than the <svg></svg> tags and that nothing has changed in either the document or in Squiggle itself, what could possibly be causing this exception? Are there some external factors that influence SVG document validation? Thanks, -JCT
