s2sh+jqgrid整合问题！

Question

为什么都得不到数据@Override
public String execute() throws Exception {
List list = this.adminService.queryAllAdmin(this.page.curPageNo,
this.page.pageSize);
Map<String, Object> row = new HashMap<String, Object>();   Iterator ite = list.iterator();
while (ite.hasNext()) {
Admin a = new Admin();
a = (Admin) ite.next();
student.put("id", "\"" + a.getId() + "\"");
student.put("addDate", "\"" + a.getAddDate() + "\"");
student.put("email", "\"" + a.getEmail() + "\"");
student.put("isLock", "\"" + a.getIsLock() + "\"");
student.put("username", "\"" + a.getUsername() + "\"");
student.put("password", "\"" + a.getPassword() + "\"");
dataRows.add(student);
}

// 给另外三个返回参数设值
setTotalPages(1); // 总页数
setCurPage(1); // 当前页
setTotalRecords(10); // 总记录数
return SUCCESS;
}
根据下面的思路弄的，上面的就是不行，有没有人这方面的例子或者思路，谢谢分享一下，分不多，不好意思public String execute() throws Exception
        {
                // 构建几条数据
                int i = 0;
                for(i=0;i<20;++i)
                {
                        // 定义一个Map<String,Object>存放一行行数据。（跟从Servlet获得数据类似，只不过此处不需要用json-lib）
                        Map<String, Object> row = new HashMap<String, Object>();
                        row.put("id", i);
                        if(i%2==0)
                        {
                                row.put("userName", "polaris");
                                row.put("gender", "女");
                        }
                        else
                        {
                                row.put("userName", "徐新华");
                                row.put("gender", "男");
                        }
                        row.put("email", "[email protected]");
                        row.put("QQ", "772"+i+"1837"+i);
                        row.put("mobilePhone", "132"+i+"1837"+i+"3"+i);
                        row.put("birthday", "198"+i+"-10-"+"1"+i);
                        dataRows.add(row);
                }
                // 给另外三个返回参数设值
                setTotalPages(1);                // 总页数
                setCurPage(1);                        // 当前页
                setTotalRecords(i);                // 总记录数
                return SUCCESS;
        }
