ckeditor和ckfinder（java版） flash上传不显示，并且无法播放

Question

1.我上传flash的时候，服务器显示上传成功，但是不显示图像，我上传的是MP4格式的，
查看我上传的路径显示竟然是gif，双击预览还显示下载失败？
2.我上传图片准备把图片上传到项目外目录，linux服务器，不然的话每次打包成war包发布，就会把上次上传的图片给覆盖，问题是我图片上传成功了，但是确访问不到图片？ 这个csdn 我也问了，没有找到答案 http://ask.csdn.net/questions... 因为我属于二次开发，这个插件确实不懂，求各位兄弟姐妹帮助一下，感谢...
