В сервлете есть код :
ServletOutputStream servletOutputStream = response.getOutputStream(); InputStream reportStream = getServletConfig().getServletContext().getResourceAsStream("/reports/FirstRepor t.jrxml"); try { JasperRunManager.runReportToPdfStream(reportStream, servletOutputStream, new HashMap(), new JREmptyDataSource()); response.setContentType("application/pdf"); servletOutputStream.flush(); servletOutputStream.close(); } catch (JRException e) { StringWriter stringWriter = new StringWriter(); PrintWriter printWriter = new PrintWriter(stringWriter); e.printStackTrace(printWriter); response.setContentType("text/plain"); response.getOutputStream().print(stringWriter.toString()); response.getOutputStream().print(e.getMessage()); }
Но после выполнения вываливается следующая ошибка:
