How to pass data object instead of collection in Java?

@RequestMapping(value = "/generateReport", method = RequestMethod.POST)
    public ModelAndView generateReport(@ModelAttribute("MstKraEmpBean") MstKraEmpBean userBean,KrahdrBean krahdrBean, BindingResult result, RedirectAttributes redirectAttributes, ModelMap map, HttpServletRequest req) 
    {
         try {
           Map<String, Object> parameterMap = new HashMap<String, Object>();
           List<MstKraEmp> userBean1 = null;
           userBean1 = KRAService.getEmployee(17);
           JRDataSource JRdataSource = new JRBeanCollectionDataSource(userBean1);
           parameterMap.put("pDataSource", userBean1);
           parameterMap.put("pLength", 123);
           JasperPrint jasperPrint = JasperFillManager.fillReport("E:/StyledTextReport/KRA_Test.jasper",parameterMap,JRdataSource);
           File outDir = new File("E:/jasperoutput");
           outDir.mkdirs();
            JasperExportManager.exportReportToPdfFile(jasperPrint,outDir.getPath()+"/KRA_Test.pdf");
               System.out.println("Name : "+userBean1.get(0).getName() + "Pass : " + userBean1.get(0).getPwd());
               System.out.println("Size : "+userBean1.size());
        } catch (JRException e) {
            e.printStackTrace();
        }

           System.out.println("Done!");
        return new ModelAndView("Report");

}

I want to use Data Object instead of List Because i face the issue to print the name in jasper report example : $P{pDataSource}.get(0).getName() : But Issue
