Hi
I am able to run the fo from command line and get the printed output.
Now the next is to embed in servlet.
I tried running this servlet from jbuilder.
with the library pointing to fop.jar,xalan.jar xcerces.jar , batik.jar,
buildtools.jar
I run into following error.
javax.xml.transform.TransformerConfigurationException: Namespace not
supported by SAXParser

import javax.xml.transform.stream.StreamSource;
import javax.xml.transform.stream.StreamResult;
public class fotest extends HttpServlet {
/**Initialize global variables*/
public void init() throws ServletException {
}

response) throws ServletException, IOException {
try{
XMLReader xmlreader =createParser();
Writer writer = new StringWriter();

File xmlfile = new File("d:\\temp\\Footnotes.xml");

transformer.transform(xmlSource, xmlResult);

Reader reader = new StringReader(writer.toString());
writer.flush();
writer.close();

driver.setRenderer("org.apache.fop.render.pdf.PDFRenderer",".14");

// send pdf writer output to a byte array stream
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PrintWriter printWriter = new PrintWriter(baos);
//driver.setWriter(printWriter);
driver.setOutputStream(baos);
driver.buildFOTree(xmlreader, new InputSource(reader));
driver.format();
driver.render();
// send the bytes out to the servlet output stream
response.setContentType("application/pdf");
response.setContentLength(baos.size());
long sixty = System.currentTimeMillis() + 60*1000;
response.setDateHeader("Expires", sixty);
baos.writeTo(response.getOutputStream());
response.getOutputStream().flush();
}
catch (Exception e) {
System.out.println(e);
}
}

XMLReader xmlreader = null;
try {
String parserClassName = System.getProperty("org.xml.sax.parser");
if (parserClassName == null) {
parserClassName = "org.apache.xerces.parsers.SAXParser";
}
xmlreader= (XMLReader) Class.forName(parserClassName).newInstance();
} catch (Exception e) {
System.out.println(e);
}
return xmlreader;

Do let me know what the problem is .
Thanks in advance.
