在项目中使用了WebUpload视频上传，由于对WebUpload的配置参数上不是很了解，走了不少弯路，以下是整理出来的代码。 前台jsp页面只有通过iframe引入该文件即可。

前台页面引入方式：
<tr> <td class="value" width="20%"><label class="Validform_label">视频上传</label></td> <td class="txt_value" colspan="3"> <div style="width:588px;height: 312px;"> <iframe scrolling="no" frameborder="0" id="FrameVideoID" name="FrameVideoID" src="<%=path%>/res/image-upload/file_uploadMutil.jsp" style="width:90%;height:100%;"></iframe> <input type="hidden" id="files" name="files"/> <input type="hidden" id="filenames" name="filenames"/> </div> </td> </tr>引入WebUpload的js和css等文件，最后运行效果如下。
