Hello!
I have some problems embedding FOP 0.92b with an overridden Print-Renderer,
similar to the ExampleFO2OldStylePrint.java example.
Her is my simplified sourcecode:
class printFO
{
public static void main(String[] args)
{
try {
PrinterJob printerJob = PrinterJob.getPrinterJob();
PrintRenderer p_renderer = new PrintRenderer(printerJob);
FopFactory fopFactory = FopFactory.newInstance();
FOUserAgent foUserAgent= fopFactory.newFOUserAgent();
foUserAgent.setRendererOverride(p_renderer);
Fop fop= fopFactory.newFop(MimeConstants.MIME_FOP_PRINT,
foUserAgent,
null);
File sourcefile=new File(args[0]);
String baseURL = null;
baseURL = new File(sourcefile.getAbsolutePath()).
getParentFile().toURL().toExternalForm();
foUserAgent.setBaseURL(baseURL);
Result res = new SAXResult(fop.getDefaultHandler());
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer;
transformer = factory.newTransformer();
// Create a SAXSource from the input Source file
Source src = new StreamSource(sourcefile);
// Start XSLT transformation and FOP processing
transformer.transform(src, res);
} catch (Exception e) {
e.printStackTrace();
}
}
}
This program works fine until I do not refer external images. When I do so,
Java comes to a NullPointerException. Here my example FO-File:
<?xml version="1.0" encoding="UTF-8"?>
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format";
xmlns:svg="http://www.w3.org/2000/svg";>

<fo:simple-page-master margin-bottom="0.5cm" margin-left="1.5cm"
margin-right="0.5cm" margin-top="1.1cm" master-name="A4"
page-height="29.7cm" page-width="21cm">
<fo:region-body column-count="1" column-gap="0.5cm" region-name="Layout"/>
</fo:simple-page-master>
</fo:layout-master-set>
<fo:page-sequence master-reference="A4">
<fo:flow flow-name="Layout">
<fo:block>
Test!

When I commended out the line overriding the Renderer, then everythings is
ok (but I cannot control the PrinterJob, and so it is no solution).
Any suggestions to this problem?
CU Immo!
PS.: My main point is to direct the printer output to a special printer and
a special tray, so I need this PrinterJob instance. If you have an
alternative way to do so: please drop me a note!
