为什么小弟我取到的textarea值为空啊

<form action="<%=path %>/GetAddUpAction?key=getGywm&method=Add" method="post" id="myform" name="myform" enctype="multipart/form-data">
                    <table class="insert-tab" width="100%">
                        <tbody>
                            <tr>
                                <th>内容：</th>
                                <td> <textarea id="TextArea1" cols="20" rows="2" name="textarea" class="ckeditor"></textarea></td>
                            </tr>
                            <tr>
                                <th></th>
                                <td>
                                    <input class="btn btn-primary btn6 mr10" value="提交" type="submit">
                                    <input class="btn btn6" onClick="history.go(-1)" value="返回" type="button">
                                </td>
                            </tr>
                        </tbody>
                     </table>
                </form>

else if (method.equals("Add")) {
			try {
				String about = req.getParameter("textarea");
				System.out.println(about);
