AW: AW: large tables loop problem

[Tobias Kuhn <tk...@mailserv.rz.fh-muenchen.de>]

Hello,
 
i don't know how to view my xslt result.
i am working on a project , where all the data of the software can be
saved to xml...
now i want to create a pdf report file out of the xml data, and i only
provide and xsl file with FO tags.
so i have written a java class with the following code:
 
{
// create XML Tree with project data
  Document doc = DocumentFactory.getInstance().createDocument();
  YpiXML ypiXML = new YpiXML(projekt);
 
  ypiXML.setFile(outFile);
  ypiXML.saveProjektDaten(doc, true);
 
 OutputStream xmlstream = new ByteArrayOutputStream();
 ByteArrayInputStream istream = null;
 String s = "";
 OutputFormat outFormat = new OutputFormat();
 outFormat.setEncoding("windows-1252");
 XMLWriter writer = new XMLWriter(xmlstream,outFormat);
 writer.write(doc);
 writer.flush();
 s = xmlstream.toString();
 stream = new ByteArrayInputStream(s.getBytes());
String stemp = istream.toString();
 istream.close();
Source strSource = new StreamSource(new StringReader(s));
TransformerFactory transformerFactory = TransformerFactory.newInstance
();
  
Templates template = transformerFactory.newTemplates(new
StreamSource(xslFile));
Transformer transformer = template.newTransformer();
Driver driver = new Driver();
driver.setRenderer(driver.RENDER_PDF);
FileOutputStream fo = new FileOutputStream(outFile);
driver.setOutputStream(fo);
Result saxResult = new SAXResult( driver.getContentHandler() );
transformer.transform( strSource, saxResult );

driver.reset();
fo.flush();
fo.close();
}

This works very well, i only have to provide an xsl File that contains
the information, which data of the xml file should be shown in the pdf.
when a table larger than one pdf (A4) page has to be created, the
endless loop appears. otherwise it runs with no problem...
 
As i am really new to FOP, any hints are welcome,
 
regards, 
 
T. Kuhn

I can't reproduce the problem. 

Posting snippets form the XSLT is unwise, you should post 
the result of the XSL transformation, after trimming it 
to the part which actually demonstrates the problem, and 
perhaps anonymizing company data. 

I guess you'll spot the problem yourself when looking 
at the XSLT result.

Hey, be a bit more creative!

This is really ugly. Look up javax.xml.transform.dom.DOMSource.

Omit the driver, and use
  transformer.transform( strSource, new StreamResult(new File("file.fo")));
