在网页中输入id点查询，显示id和name，求怎么做？？
如下图所示：我做好了输入name，显示id和name的

下面是java代码
    public List<JspDepartment> getJspDepartment() throws SQLException
    {

        List<JspDepartment> jspList = new ArrayList<JspDepartment>();
        List<Department> departmentList = departmentManage.queryAll();

        for (int i = 0; i < departmentList.size(); i++)
        {
            JspDepartment jspDepartment = new JspDepartment();

            jspDepartment.setId(departmentList.get(i).getId());

            jspDepartment.setName(departmentList.get(i).getName());
            jspList.add(jspDepartment);
        }

        return jspList;
    }

    public List<JspDepartment> getJspDepartment(String departmentName)
            throws SQLException
    {

        List<JspDepartment> jspList = new ArrayList<JspDepartment>();
        List<Department> departmentList = departmentManage
                .query(departmentName);

        for (int i = 0; i < departmentList.size(); i++)
        {
            JspDepartment jspDepartment = new JspDepartment();

            jspDepartment.setId(departmentList.get(i).getId());

            jspDepartment.setName(departmentList.get(i).getName());

            jspList.add(jspDepartment);
        }

        return jspList;
    }
jsp代码：
     <form action="tree2.jsp">
            <p class="serial">编号：001</p>
            <input class="serial"></input>
            <p class="name">机构名：中队1</p>
            <input name="name" class="name"></input>
            <button id="edit">修改</button>
            <button id="del">删除</button>            
            <input  type="submit" name="sub" value="查询" />
