Question

我从PLSQL Dev调用一个java类。我的Logger.java用字符串＆＃34; C：\ Logs \ mylog.TXT＆＃34;

调用FileHandler

fileHndlr = new FileHandler(logFileName, false);

结果是：

Exception in thread "Root Thread" java.lang.Error: java.io.IOException: sjonfile_fileinfo fais to get fileinfo
    at sun.nio.ch.FileKey.create(FileKey.java:41)

创建文件似乎缺少一些权限，需要检查什么？

更新：

我们将processmonitor安装到发生文件操作的服务器上，我们发现了两个可疑事件：

Answer 1

需要使用sysdba用户执行以下操作：

GRANT READ,WRITE ON DIRECTORY userDirectory TO userSchema;

Execute dbms_java.grant_permission('userSchema', 'java.io.FilePermission', 'userDirectory/*', 'read,write,execute,delete');

FileHandler在FileKey上导致IOException
