Pascal,
The method that I am using in my code follows:
public void convertFO2PDF(OPFReader opfReader, File resultfile)
throws IOException, FOPException {
OutputStream out = null;
try {
//configure user agent
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
//PDF/A-1b
Boolean isPDFA =
Boolean.parseBoolean(FrameMain.applicationProps.getProperty("pdfA"));
if (isPDFA) {
foUserAgent.getRendererOptions().put("pdf-a-mode", "PDF/A-1b");
}
//Accessible PDF
Boolean isAccessiblePDF =
Boolean.parseBoolean(FrameMain.applicationProps.getProperty("accessiblePDF"));
if (isAccessiblePDF) {
foUserAgent.setAccessibility(true);
}
foUserAgent.setTitle(opfReader.getTitle());
foUserAgent.setSubject(opfReader.getSubject());
foUserAgent.setKeywords(opfReader.getIdentifier());
foUserAgent.setProducer("NIMAS2PDF");
File foFile = new File(xmlDir, opfReader.getIdentifier() + ".fo");
//debug message
logger.info("Transforming " + foFile.getName() + " to PDF.");
logger.info("Using " + xsltFile.getName() + " for tranformation.");
// setup output based on parameter
out = new java.io.FileOutputStream(resultfile);
out = new java.io.BufferedOutputStream(out);
// Construct fop with desired output format
Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF,
foUserAgent, out);
// Setup JAXP using identity transformer
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(); //
identity transformer
// Setup input stream
Source src = new StreamSource(foFile);
// Resulting SAX events (the generated FO) must be piped
through to FOP
Result res = new SAXResult(fop.getDefaultHandler());
// Start XSLT transformation and FOP processing
transformer.transform(src, res);
// Result processing
FormattingResults foResults = fop.getResults();
java.util.List pageSequences = foResults.getPageSequences();
for (java.util.Iterator it = pageSequences.iterator();
it.hasNext();) {
PageSequenceResults pageSequenceResults =
(PageSequenceResults) it.next();
logger.info("PageSequence " +
(String.valueOf(pageSequenceResults.getID()).length() > 0
? pageSequenceResults.getID() : "<no id>") + "
generated " + pageSequenceResults.getPageCount() + " pages.");
}
logger.info("Generated " + foResults.getPageCount() + "
pages in total.");
} catch (Exception ex) {
logger.severe(ex.getMessage());
} finally {
out.close();
}
}
I believe the error is actually being thrown by FOP. The
AbstractLayoutManager class has the following method:
private void verifyNonNullPosition(Position pos) {
if (pos == null || pos.getIndex() < 0) {
throw new IllegalArgumentException(
"Only non-null Positions with an index can be checked");}
I am at a loss as to what a no null position even is. I'm also a bit
confused that your not getting the error on your end. Perhaps if I
knew a bit more about the nature of the verifyNonNullPosition method.
Thanks,
