The SAX exception occurs in Tansformer.transform() for a very large xml string
as input
----------------------------------------------------------------------------------------
Key: XALANJ-2537
URL: https://issues.apache.org/jira/browse/XALANJ-2537
Project: XalanJ2
Issue Type: Bug
Security Level: No security risk; visible to anyone (Ordinary problems in
Xalan projects. Anybody can view the issue.)
Components: SAX
Affects Versions: 2.7
Environment: Linux
Reporter: Deepthi BakkaVemana
Priority: Blocker
We are using xalan 2.7.0 and fop 0.95 for generating PDF reports.While
generating pdf report for a large xml string of 2,96,126 characters(~ nearly 3
lakh characters) ,the PDF generation fails and it fails at
transformer.transform() method in TransformerImpl.java.Since in our product,we
need large reports with very large strings(events),we need this fix ASAP.
TransformerFactory factory = TransformerFactory.newInstance();
Templates templates = factory.newTemplates(new
SAXSource(new InputSource(
new StringReader(xslContent))));
Transformer transformer = templates.newTransformer();
// Set the value of a <param> in the stylesheet
transformer.setParameter("versionParam", "2.0");
Result res = new SAXResult(fop.getDefaultHandler());
String parserClass =
"com.sun.org.apache.xerces.internal.parsers.SAXParser";
if (((String)
System.getProperties().get("java.version")).startsWith("1.4"))
{
parserClass =
"org.apache.crimson.parser.XMLReaderImpl";
}
//String parserClass =
"org.apache.crimson.parser.XMLReaderImpl";
XMLReader reader =
XMLReaderFactory.createXMLReader(parserClass);
Source source = new SAXSource(reader, new
InputSource(bufferedInputStream));
transformer.transform(source, res); - this is the
point of failure..
