Downloading pdf inside adf region issue

Question

All,
I am trying to download a pdf inside a region. My code to download it is
        InputStream ios = Thread.currentThread().getContextClassLoader().getResourceAsStream("StatementReport.jrxml");
        Map parameters = new HashMap();
        parameters.put("PAR_CUSTOMER_ID", customerId.toString());
        parameters.put("SUBREPORT_DIR", "./");
        parameters.put("rowid", statementRowId.toString());
        Connection connection = null;
        try {
            HttpServletResponse response =  (HttpServletResponse)FacesContext.getCurrentInstance().getExternalContext().getResponse();
            ServletOutputStream servletOutputStream;
            servletOutputStream = response.getOutputStream();
            byte[] bytes = null;
            //this will give us the existing connection from the AM
            ob = bc.getOperationBinding("getCurrentConnection");
            ob.execute();
            connection = (Connection)ob.getResult();
            //This will create a new connection alltogether.
            /* Context ctx = new InitialContext();
            Context envCtx = (Context)ctx.lookup("");
            DataSource ds = (DataSource)envCtx.lookup("jdbc/om");
            if (ds != null) {
                    connection = ds.getConnection();
            JasperDesign jasperDesign = JRXmlLoader.load(ios);
            JasperReport jasperReport =   JasperCompileManager.compileReport(jasperDesign);
            bytes = JasperRunManager.runReportToPdf(jasperReport, parameters,  connection);
            response.addHeader("Content-disposition",  "attachment;filename=statement.pdf");
            response.setContentType("application/pdf");
            response.setContentLength(bytes.length); //commented this also as mentioned in a number of post. Also tried adding buffersize to the response object but no progress
            servletOutputStream.write(bytes, 0, bytes.length);
            servletOutputStream.flush();
            servletOutputStream.close();
            context.responseComplete();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (JRException e) {
            e.printStackTrace();
        } /*catch (NamingException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        } */catch(Exception e){
            e.printStackTrace();
        }I get the following error and the pdf dosent open

Answer 1

i even removed the Jsaper related code and tried using
            byte[] content =
                  { '<', 'H', 'T', 'M', 'L', '>', '<', 'B', 'O', 'D', 'Y', '>', 'H', 'e', 'l', 'l', 'o', '<', '/', 'B', 'O', 'D',
                    'Y', '>', '<', '/', 'H', 'T', 'M', 'L', '>' };but the error is there. So for sure it has nothing to do with Jasper reports
Also the form that has region has usesupload property set to true
