It processes and then throws and exception on which I am stuck. Please help.
I am attaching ths stack trace and the fop file(attachment) and the code as well at the bottom:
CODE:
public void convertFO2PDF() throws IOException, FOPException
{
OutputStream out = null;
try
{
File fo = new File("c:/indata.fo");
File pdf = new File("c:/indata.pdf");
System.out.println("HERE NOW");
// Construct fop with desired output format
Fop fop = new Fop(MimeConstants.MIME_PDF);
System.out.println("AFTER HERE NOW");
// Setup output stream. Note: Using BufferedOutputStream
// for performance reasons (helpful with FileOutputStreams).
out = new FileOutputStream(pdf);
out = new BufferedOutputStream(out);
fop.setOutputStream(out);
// Setup JAXP using identity transformer
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(); // identity transformer
// Setup input stream
Source src = "" StreamSource(fo);
// Resulting SAX events (the generated FO) must be piped through to FOP
Result res = new SAXResult(fop.getDefaultHandler());
// Start XSLT transformation and FOP processing
System.out.println("START TRANSFORMING DATA");
transformer.transform(src, res);
System.out.println("FINISHED TRANSFORMING DATA");
// 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();
System.out.println("PageSequence "
+ (String.valueOf(pageSequenceResults.getID()).length() > 0
? pageSequenceResults.getID() : "<no id>")
+ " generated " + pageSequenceResults.getPageCount() + " pages.");
}
System.out.println("Generated " + foResults.getPageCount() + " pages in total.");
} catch (Exception e) { e.printStackTrace(System.out);}
finally {
if(out != null)
out.close(); }
}
