I'm using fop in a servlet to render pdf from a jdom document and an xsl
stylesheet.
It works fine if I write the pdf to a file, but if I write it back to the
HttpResponse object I get a mime type of "application/octet-stream" even
though I'm setting it to "application/pdf"
code snippets follow:
from servlet.doGet method
-----------------------------------------------------------
jdom.Document dataxml = XmlTools.getDocument(xml);
PdfRenderer Pdf = new PdfRenderer(xsl);
response.setContentType("application/pdf");
OutputStream os = response.getOutputStream();
Pdf.writePdf(dataxml, os);
from PdfRenderer.java
---------------------------------------------------------------
public class PdfRenderer {
private File XsltFile;
private Driver driver;
private Transformer transformer;
public PdfRenderer(URL xsltUrl)throws Exception {
InputStream is = xsltUrl.openStream();
Source xsltSrc = new StreamSource(is);
setup(xsltSrc);
}
private void setup(Source xsltSrc)throws TransformerConfigurationException
{
driver = new Driver();
Logger logger = new ConsoleLogger(ConsoleLogger.LEVEL_INFO);
driver.setLogger(logger);
driver.setRenderer(Driver.RENDER_PDF);
TransformerFactory transformerFactory =
TransformerFactory.newInstance();
transformer = transformerFactory.newTransformer(xsltSrc);
}
public void writePdf(Document doc, OutputStream os) throws Exception {
writePdf(new JDOMSource(doc), os);
}
private void writePdf(Source data, OutputStream pdfos)throws
TransformerException {
driver.setOutputStream(pdfos);
Result res = new SAXResult(driver.getContentHandler());
transformer.transform(data, res);
}
