Transfer of file to a shared folder on remote machine

Question

Hi,
I want to transfer a file present on windows machine A to a shared folder (\\16.192.54.56\Test) on machine B having ip as 16.192.54.56, using java.
I tried using the renameTo api of File class but its not helping. It gives permission denied exception. I am able to open the shared folder from machine A using the shared folder path (\\16.192.54.56\Test) through the run command. So, that means there is no permission issue on the shared folder.
Could anybody please guide me as to how can i resolve this issue.

Hi,
Please pardon me for not providing the complete information.
I have kind of root caused the issue. Let me explain the issue in detail.
I have a logic to move a file to a shared folder on remote machine, inside my application running on a different machine. Now when i run my application using
command prompt, the logic of moving the file to the shared folder works fine.
        try
            File fDest = new File(""\\\\15.154.52.100\\TestDir\\test");
            File fSrc = File.createTempFile("testExport", "txt");
           final int BUFFER = 2048;
           InputStream in = new FileInputStream(fSrc);
           OutputStream out = new FileOutputStream(fDest);
           // Transfer bytes from in to out
           byte[] buf = new byte[BUFFER];
          int len;
          while ( (len = in.read(buf)) > 0)
              out.write(buf, 0, len);
          in.close();
         out.close();
         fSrc.delete())
        catch (Exception ex)
            ex.printStackTrace();
{code}
But when i run my application as a windows service, the logic does not work.
I noticed that when we run our application as windows service, the owner of JVM is System and it looks like it will not have Network access permission.
But, when we run our application through command prompt or as a standalone application, then the owner will be the user who started the application. This user will have the Network access permission.
Please correct me if the above assumption is correct. If this is the case then how can i make my application (running as windows service), to have network access permission.
