Hi all,

I was implement to print function for a scheduling gantt and use the sample code in this post https://community.oracle.com/message/2782685#2782685

This is my implementation for the handling method.

       
        if (GanttActionEvent.PRINT == ganttActionEvent.getActionType()) {
            try {
                FacesContext context = FacesContext.getCurrentInstance();
                HttpServletResponse response = (HttpServletResponse)
                          context.getExternalContext().getResponse();
                response.setContentType("application/pdf");
                OutputStream sos = response.getOutputStream();
               
                // Generate FO
                GanttPrinter printer = new GanttPrinter(schedulingGantt);
                File file = File.createTempFile("gantt", "fo");
                OutputStream out = new FileOutputStream(file);
                printer.print(out);
                out.close();
               
                // generate pdf
                FOProcessor processor = new FOProcessor();
                processor.setData(new InputStreamReader(new FileInputStream(file), "UTF-8"));
                processor.setOutputFormat(FOProcessor.FORMAT_PDF);
                processor.setOutput(sos);
                processor.generate();
                sos.close();
                context.responseComplete();

            } catch (Exception ex) {
                //handler
                ex.printStackTrace();
            }
        }                                          
    }

In line 22, the FOProcessor.generate method , I got an exception like this.

Does anyone know what the problem is?
