Hello,
I have an eclipse ide svg viewer that shows svg in a tabbed fashion, using
JSVGCanvas. I have overridden the SAXSVGDocumentFactory. I am mainly trying to
move to batik1.7 to see if the java heap issue (using batik1.6 libs) that i
encounter on opening about 6 to 7 jsvgcanvas instances to display 6 or more
svgs go away.
public class EclipseSAXSVGDocumentFactory extends SAXSVGDocumentFactory {
public EclipseSAXSVGDocumentFactory(String parser, boolean dd) {
super(parser, dd);
}
protected Document createDocument(InputSource is) throws IOException {
try {
Thread.currentThread().setContextClassLoader(getClass().getClassLoader());
System.setProperty("javax.xml.parsers.SAXParserFactory",
SAXParserFactoryImpl.class.getName());
SAXParserFactory factory = SAXParserFactory.newInstance();
factory.setFeature("http://xml.org/sax/features/namespaces";, true);
factory.setFeature("http://xml.org/sax/features/namespace-prefixes";, true);
factory.setFeature("http://xml.org/sax/features/validation";,
isValidating);
SAXParser parser = factory.newSAXParser();
parser.getXMLReader().setContentHandler(this);
parser.getXMLReader().setDTDHandler(this);
parser.getXMLReader().setEntityResolver(this);
parser.getXMLReader().setErrorHandler((errorHandler == null) ? this
: errorHandler);
parser.setProperty("http://xml.org/sax/properties/lexical-handler";,
this);
parser.getXMLReader().parse(is);
} catch (SAXException e) {
Exception ex = e.getException();
if (ex != null && ex instanceof InterruptedIOException) {
throw (InterruptedIOException) ex;
}
throw new IOException(e.getMessage());
} catch (ParserConfigurationException e) {
throw new IOException(e.getMessage());
}
currentNode = null;
Document ret = document;
document = null;
return ret;
}
}
But on my createDocument i get the following exception:
java.lang.NullPointerException

org.apache.batik.swing.svg.SVGDocumentLoader.run(SVGDocumentLoader.java:84)
When i debug the inputsource is not null and the xmlreader is
org.apache.xerces.SAXParser in batik1.7. But for batik 1.6 the parser is
org.apache.xerces.jaxp.SAXParserImpl.
This code worked perfectly with batik1.6 but not on 1.7 does anybody have any
pointers on what is wrong?
Thanks,
Emmy
