     import org.springframework.ui.Model;
     //.....
    @RequestMapping("/accounts/personal/list")
    public String list(Model model){

        try { 
            
            ArrayOfAccount result = port.getAccounts( null, 0, 20);
              //i thought with this i can grab the result collection.
              model.addAttribute(result);
        } catch (Exception ex) {
            // TODO handle custom exceptions here
        }

        return "accountslist";
    }
