Copying files over network shared folder using Java

Problem :: One of my blog reader posted a problem that he cannot copy files over a network shared folder using java.

Solution :: Java alone doesn't have support for networked file sharing. But if you use a library, like Samba, then you can. 

http://jcifs.samba.org/

You can check below source code which successfully copies file from my local drive to a shared network folder ::

  copyFileUsingJcifs(domain,userName, password, sourcePath, destinationPath);

  System.out.println("The file has been copied using JCIFS");

 }

 public static void copyFileUsingJcifs(final String domain,final String userName,

   final String password, final String sourcePath,

   final String destinationPath) throws IOException {

  final NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(

    domain, userName, password);

  final SmbFile sFile = new SmbFile(destinationPath, auth);

  final SmbFileOutputStream smbFileOutputStream = new SmbFileOutputStream(

    sFile);

  final FileInputStream fileInputStream = new FileInputStream(new File(

    sourcePath));

  final byte[] buf = new byte[16 * 1024 * 1024];

  int len;

  while ((len = fileInputStream.read(buf)) > 0) {

   smbFileOutputStream.write(buf, 0, len);

  }

  fileInputStream.close();

  smbFileOutputStream.close();

 }

  

}
