Extjs如何获取后台方法返回的值然后前台接收值再把此值放入action url里进行load加载

前台://把上传的 文件发送到相应Action
function upload(){
var tml = document.getElementById("fileId");

if(tml.value == ''){
Ext.MessageBox.alert('提示','请选择需要上传文件');
return;
}
Ext.Ajax.request({
url: '../manager/print!excelUpload.action',
form: Ext.fly('uploadForm'),
waitMsg: "正在保存数据...",
headers: {'Content-type':'multipart/form-data'},
isUpload: true,

success: function(response) {

var jsonObj = Ext.decode(response.responseText);
store.load();
},

failure: function (response) {

if(Ext.util.JSON.encode(response.status)==0){
Ext.MessageBox.alert('提示','无法连接到服务器,请检查网络是否正常');
} else {
Ext.MessageBox.alert('提示','操作出现异常,请与系统管理员联系');
}

}

    });           

这是后台:
public String excelUpload() throws FileNotFoundException, IOException {

     //获取当前系统时间时分秒
     SimpleDateFormat st = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 
     String time = st.format(new Date());

     //获取文件路径转换输入流
     InputStream is =new FileInputStream(filenPathname);  
    //解析出来的 字符格式
      WorkbookSettings workbookSettings = new WorkbookSettings();     
      workbookSettings.setEncoding("GBK");
        try {
        //创建工作薄对象  (Excel对象)
        Workbook work  =Workbook.getWorkbook(is,workbookSettings);
        //获取工作薄中表  
        Sheet sheet =work.getSheet(0);
        int rows = sheet.getRows();//获取总行数、
        int cell  =sheet.getColumns();//获取总列数
        System.out.println(rows);
        System.out.println(cell);
        //循环所有行数

        for (int i = 1; i < rows; i++) {  
             PtUploadOrderTmp  pt= new PtUploadOrderTmp();
             System.out.println("------------" + i);  
             String[] str = new String[cell];
             //循环行下的每一列的值

                 //把每一行每一列的值循环出来

             pt.setWaybillNo(sheet.getCell(0, i).getContents());    
             pt.setSenderAddress(sheet.getCell(1, i).getContents());
             pt.setSenderCompany(sheet.getCell(2, i).getContents());
             pt.setReceiverName(sheet.getCell(3, i).getContents());
             pt.setReceiverPhone(sheet.getCell(4, i).getContents());
             pt.setGoods(sheet.getCell(5, i).getContents());
             pt.setPsc(BigDecimal.ONE); //件数             6
             pt.setWeight(Double.valueOf(sheet.getCell(7, i).getContents()));//重量
             pt.setVolume(BigDecimal.ZERO);//体积 8
             pt.setCod(Double.valueOf(sheet.getCell(9, i).getContents()));//代收货款
             pt.setPayment(sheet.getCell(10,     i).getContents());//付款方式
             try {
                pt.setSendDate(new SimpleDateFormat("yyyy-MM-dd").parse(sheet.getCell(11, i).getContents()));
            } catch (ParseException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }//发送时间
             pt.setIsPrint(sheet.getCell(12, i).getContents().equals("是"));//是否打印
             pt.setIsUpload(sheet.getCell(13, i).getContents().equals("是"));//是否上传
             pt.setRemark1(sheet.getCell(14, i).getContents());//备注
             pt.setBatchNo(time);    //批次号
             oderService.save(pt);
         }  
    } catch (BiffException e) {     
        // TODO Auto-generated catch block
        e.printStackTrace();
    } 

    return ajaxJson(time);
  }
