Create folder in a mapped network drive using Java

Question

I'm trying to create a folder to a mapped network drive Z: using Java

Unfortunately the file is not getting created. This is what I'm doing:

File file = new File("Z:/file1");
file.mkdir();

This code works when not using mapped network drive. This is on Windows environment.

Any ideas?

Do you have permissions to create this directory. Try creating the directory in explorer. — Peter Lawrey, Jan 04 '11 at 21:17
This java code is under a web application running under Tomcat 5.5 — Marquinio, Jan 04 '11 at 21:35
Back to Peter Lawrey's question - is the web application running as a Windows Service? Or did you manually start Tomcat using a .bat file? — Dan, Jan 04 '11 at 22:20
Ok yes Tomcat is running under a Windows Service. I just took that same piece of code running under Tomcat and created a small test JAR that would create the folder on mapped drive and it worked. I guess is privileges issues that Tomcat has. — Marquinio, Jan 05 '11 at 15:29

Ok I figured this out. Tomcat is running under Windows 2003 Server. According to what I found is that when Tomcat is started under the Windows Services, for some reason it doesn't have access to the mapped network drive. Using UNC paths worked for me.

File myFile = new File("\\\\server\\shared\\input");
myFile.mkdir();

I was able to create a folder on the mapped network drive on that server.
