This is how i thought to do it and that someone else (Lakshmi) made
working :) using DOM instead of (File)Streams.

Aihe: FOP and DOM Success
I tried for long and with the help of fop-dev archive got my FOP servlet to
work with a DOM .
Here comes the code . I hope it is useful to someone down the line !
public void renderXML(HttpServletResponse response) throws ServletException
{
try {
//Instantiate a DocumentBuilderFactory, needed for parsing XML
documents from text format
DocumentBuilderFactory dFactory =
DocumentBuilderFactory.newInstance();
// And setNamespaceAware, which is required when parsing xsl files
dFactory.setNamespaceAware(true);
//Use the DocumentBuilderFactory to create a DocumentBuilder.
DocumentBuilder dBuilder = dFactory.newDocumentBuilder();
/**************************************************************/
FileInputStream xmlfile = new
FileInputStream("c:\\bea\\wlserver6.0\\contact.xml" );
Document xmlDoc = dBuilder.parse(xmlfile);
javax.xml.transform.dom.DOMSource xmlDomSource = new
javax.xml.transform.dom.DOMSource(xmlDoc);
/************************************************************/
/************************************************************/
FileInputStream xsltFile = new FileInputStream("contactFO.xsl");
org.w3c.dom.Document xslDoc = dBuilder.parse(xsltFile);
javax.xml.transform.dom.DOMSource xslDomSource = new
javax.xml.transform.dom.DOMSource(xslDoc);
javax.xml.transform.TransformerFactory tFactory =
javax.xml.transform.TransformerFactory.newInstance();
javax.xml.transform.Templates templates =
tFactory.newTemplates(xslDomSource);
javax.xml.transform.Transformer transformer =
templates.newTransformer();
/*************************************************************/
javax.xml.transform.dom.DOMResult foDomResult = new
javax.xml.transform.dom.DOMResult();
transformer.transform(xmlDomSource, foDomResult);
// Avoiding this step was what gave the null pointer exception !
org.w3c.dom.Document foDoc
=(org.w3c.dom.Document)foDomResult.getNode();
ByteArrayOutputStream out = new ByteArrayOutputStream();
response.setContentType("application/pdf");
org.apache.fop.apps.Driver driver = new
org.apache.fop.apps.Driver();
driver.setErrorDump(true);
driver.setRenderer(driver.RENDER_PDF);
driver.setupDefaultMappings() ;
driver.setOutputStream(out);
driver.render(foDoc);
byte[] content = out.toByteArray();
response.setContentLength(content.length);
response.getOutputStream().write(content);
response.getOutputStream().flush();
}catch(FileNotFoundException fnf)
{
fnf.printStackTrace();
}
catch (Exception ex) {
throw new ServletException(ex);
}
}
