Java PROPFIND不受支持的版本为8.5

我的同事在将生成的电子表格下载到浏览器时，在WebSphere8.5.5中获得以下跟踪。一些谷歌显示这与WebDAV有关，但我们只是想下载一个电子表格。下载仍然成功，但我们不想让它进入生产阶段，并将他目前在RAD中与WAS本地合作的日志弄得乱七八糟

有没有人知道，如果有某种提供电子表格的方法根本不会触发它，那么由于该功能确实有效或者更好，如何抑制此消息

此错误不会影响性能。顺便说一句，要消除此错误，请尝试

1.更改IHS的httpd.conf，如下所示

LoadModule rewrite_module modules/mod_rewrite.so 
 RewriteEngine On 
 RewriteCond %{REQUEST_METHOD} ^PROPFIND 
 RewriteRule .* - [F] 

别忘了重新启动IHS 2.使用更新版本的lib编译代码，例如使用commons-io-1.4.jar、comons-fileupload-1.2.1.jar等
