Help withcalling Windows *.exe programs that require a Windows account

Question

I am trying to use robocopy.exe (basically a better version of xcopy) to copy files from \\serverA\sahrename to \\serverB\\sharename from serverC running the java program. Here is my code:
Process p = Runtime.getRuntime().exec("robocopy \\\\serverA\\sharename \\\\serverb\\sharename *.*");This failes with an error code of 2(whatever that means). When I run the same command from the command line, it works fine.
robocpy.exe uses my login credentials to access the network share drives. The share drives are set up to give my user full access.
So the question is...
Can I run a Java program as a Windows user? I can't install my program as a Windows service because I need to run the program on demand, and not all the time.
Thanks!

Answer 1

I thought it was pretty clear that I was specificying a path: \\serverA\sharename This is a share path in Windows, and they do not have drive letters. Don't confuse a mapped drive with a share drive. A mapped drive is accessed using a drive letter such as Y:\dirname whereas a share is access by \\servername\sharename
This is from the robocopy doc
Examples:
:: Copy files from one server to another
ROBOCOPY \\Server1\reports \\Server2\backup *.doc /S /NPAs you can see, the only path specified is a share path.
I did take the advice of the other posters, and reported that it made no difference with a drive letter, it still failed.
Yes, I do know that my path is correct, because , again, like I stated in my post, it works on the command line. The same exact command works on the command line.
dcminter, does have a high post count give one the right to make unhelpful comments? Also, read my post closer next time before responding.
