I am trying to access files from a shared drive using SMB Java Library.
I am trying it in two ways
a) SMB JCIFS b) hierynomus
but both the ways I am getting exception, below is the code and exception I am getting
JCIFS
try {
String path = "smb://" + remote_machine_name + "/" + sharedFolder+"/";
NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication("", remote_user_id, remote_user_password);
SmbFile smbFile = new SmbFile(path, auth);
System.out.println("Connected");
SmbFile[] smbFileList = smbFile.listFiles();
for (SmbFile file : smbFileList) {
System.out.println(file.getName());
}
System.out.println("Done");
} catch (SmbException se) {
se.printStackTrace();
}
Exception:
jcifs.smb1.smb1.SmbException: Failed to connect: <hostname>/<ip address>

java.net.SocketException: Connection reset
hierynomus smbj
SmbConfig cfg = SmbConfig.builder().withSecurityProvider(new BCSecurityProvider()).build();
SMBClient client = new SMBClient(cfg);
Connection connection;
try {
connection = client.connect(remote_machine_name);
Session session = connection
.authenticate(new AuthenticationContext(remote_user_id, remote_user_password.toCharArray(), null));
DiskShare share = (DiskShare) session.connectShare(sharedFolder);
Set<FileAttributes> fileAttributes = new HashSet<>();
fileAttributes.add(FileAttributes.FILE_ATTRIBUTE_DIRECTORY);
Set<SMB2ShareAccess> shareAccesses = new HashSet<SMB2ShareAccess>();
shareAccesses.add(SMB2ShareAccess.FILE_SHARE_READ);
for (FileIdBothDirectoryInformation f : share.openDirectory(
"folder1/folder11/folder111",
EnumSet.of(AccessMask.FILE_READ_DATA), fileAttributes, shareAccesses,
SMB2CreateDisposition.FILE_OPEN, null)) {
System.out.println(f.getFileName());
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Exception(complete stack trace):

I manually mapped the network drive to my system and verified that I have admin rights, but for some reasons I am getting the above error.
Can someone please help me to resolve it
I have a possible solution for the SMB JCIFS way from my another answer!
SmbException failed to connect hostname/IP_address throwing with proper credentials in Java
I think the problem is you don't have SMB2 enabled in your system (thats necessary for windows 10) and you need to create a CIFSContext
object to build the proper connection between your local pc and the shared folder.
