1.jsp代码

 1   appname=$("#appname").val(); 2     $("#uploadify").uploadify({ 3       'swf' : '<%=basePath%>/Backstage/Style/jQuery-uploadify/uploadify.swf', 4       // 'script' : 'ProductAction!fileUpload.do',//后台处理的请求 5       'uploader': 'AppVersionAction!fileUpload.do?appname='+appname ,  6       'cancelImg' : '<%=basePath%>/Backstage/include/easyvalidator/images/vtip_arrow.png', 7       'folder' : '/uplaod/temp',//您想将文件保存到的路径 8       'queueID' : 'fileQueue',//与下面的id对应 9       'fileObjName':'uploadify',10       'queueSizeLimit' : 5,11       'fileDesc' : '文件格式',12       'fileTypeExts' : '*.apk;*.ipa;*.png', //控制可上传文件的扩展名，启用本项时需同时声明fileDesc13       'auto' : false,14       'multi' : true,15       'simUploadLimit' : 2,16       'buttonText' : '选择文件',17       'onQueueComplete' : function(file,data,response) { 18          picFlag = true; 19       } 20     });

1   <input type="file" name="uploadify" id="uploadify" />2         <input id="appname" type="text" value="<s:property value="version.appName"/>" name="version.appName" size="30"  maxlength="32" data-options="required:true,missingMessage:'请输入版本号'" /><font color="red">&nbsp;*</font>

2.action和service
