// Initialization
su.initialize(config, request, response);
// 上傳初始化
su.initialize(pageContext);
//1 .限制上傳文件的最大長度
su.setMaxFileSize(500*1024*1024);
su.setTotalMaxFileSize(500*1024*1024);
//2 .設定允許上傳的文件
su.setAllowedFilesList("doc,txt,html,htm,jpg,jpeg,xls,gif");
// 3.設定禁止上傳的文件
su.setDeniedFilesList("exe,bat,,");
// 上傳文件
su.upload();

忘了﹗SmartUpload su = new SmartUpload();
放前面﹗﹗

能否给我一个jspsmartupload，谢谢！
