FopServlet error in Oracle OC4J
HI, I have problems with the following code in the FopServlet that
run in Oracle OC4J:
in the FopServlet I have modified the metod renderFO to add a barcode font:
/**
* renders an FO inputsource into a PDF file which is rendered
* directly to the response object's OutputStream
*/
public void renderFO(InputSource foFile,
HttpServletResponse response) throws
ServletException {
try {
ByteArrayOutputStream out = new ByteArrayOutputStream();
response.setContentType("application/pdf");
// ---- ATT! ROWS ADDED TO ADD BARCODE FONT ----
File userConfigFile = new File("C:\\FOP\\userconfig.xml");
Options options = new Options(userConfigFile);
// ---- END ROWS ADDED -------------------------
Driver driver = new Driver(foFile, out);
driver.setLogger(log);
driver.setRenderer(Driver.RENDER_PDF);
driver.run();
byte[] content = out.toByteArray();
response.setContentLength(content.length);
response.getOutputStream().write(content);
response.getOutputStream().flush();
} catch (Exception ex) {
throw new ServletException(ex);
}
}
the error is:

I wonder what the Oracle guys did to that server that it generates so
many problems. :-)
Anyway, can you please check if you have any JAXP libraries from FOP in
the classpath (xml-api.jar, xalan.jar, xercesImpl.jar)? If yes try
removing them. Maybe something like that interferes with Oracle's JAXP
implementation.
FOP uses plain JAXP by the book in its latest version. So if anything
goes wrong with Oracle's implementation and you don't have any foreign
JAXP implementations in your classpath, I suggest you contact Oracle
support to help you, because the exception does not happen in FOP
directly but in the JAXP API (see top of stacktrace:
SAXParserFactory.newInstance).
