java - how to grant access of local file system to Wildfly server -

I am trying to write a file in java. I'm using simple "FileOutputStream" My app is positioned on " WildFly 8.0 runtime server "

My code is:

FileOutputStream fos = new FileOutputStream (new file ("c: /newfile.txt"));

I'm getting an exception:

19: 24: 36,235 error [stderr] (default task-8 ) Java.io.FileNotFoundException: c: \ newfile.txt (entry is denied)

19: 24: 36,237 error [stderr] (default Java.io.fileOutputStream.open (basic method)
