[imonks21]

I have try, this code for call report with web service datasource, but always get error  like this

this my code for call report

 public void mouseClicked(MouseEvent e) {
                try {
                    JasperReport jr = (JasperReport) JRLoader.loadObject(new File("laporan/Kasmasuksatu.jasper"));
                    HashMap param = new HashMap();
                    param.put(WebServiceDataAdapterService.URI_KEY, "http://192.168.1.5:556/");
                    param.put(WebServiceDataAdapterService.VERB_KEY, "get");
                    param.put(WebServiceDataAdapterService.LANGUAGE_KEY, LanguageType.JSON);
                    //param.put(WebServiceDataAdapterService.AUTH_PARAMETERS_KEY, "none");
                    //param.put("tipe", "0");
                    //JasperReport jr = JasperCompileManager.compileReport(new FileInputStream(new File("laporan/Kasmasuksatu.jrxml")));
                    JasperPrint jp = JasperFillManager.fillReport(jr, param);
                    JRViewer jv = new JRViewer(jp);
                    pane.mainpane.add(jv);
                    pane.mainpane.revalidate();
                } catch (JRException ex) {
                    Logger.getLogger(MainController.class.getName()).log(Level.SEVERE, null, ex);
                }
            }
