FopServlet error in Oracle OC4J

27 Feb 2003 11:26:56 -0000

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:
