Access to File Using Java with Samba Jcifs

Access to file using Java with Samba JCIFS

You are making this harder than it should be. Please follow the below steps and make sure the shared folder you are creating has write access for this user you are using.

1. download the jar file http://jcifs.samba.org/ (there is only one jar file)
2. copy and paste the below code with your information for user name, password and shared folder and that's all you need

I was running this on Linux and wanted to write to a Windows box so you want to create a shared folder and put the shared folder name in the below variable
if you don't know how to create shared folder on windows ...use google as always

    String user = "your_user_name";
    String pass ="your_pass_word";

    String sharedFolder="shared";
    String path="smb://ip_address/"+sharedFolder+"/test.txt";
    NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication("",user, pass);
    SmbFile smbFile = new SmbFile(path,auth);
    SmbFileOutputStream smbfos = new SmbFileOutputStream(smbFile);
    smbfos.write("testing....and writing to a file".getBytes());
    System.out.println("completed ...nice !");

Accessing Files using Java with Samba JCIFS

try this one

try{
            String user = "your_user_name";
            String pass ="your_pass_word";
            String sharedFolder="shared";

            String url = "smb://ip_address/" + sharedFolder + "/test.txt";
                        NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(
                                null, user, pass);
                        SmbFile sfile = new SmbFile(url, auth);
    }catch(Exception e){
    }

Simplest way to read a file using jcifs

SmbFile file = null;
byte[] buffer = new byte[1024];
try {
    String url = "smb://"+serverAddress+"/"+sharename+"/TEST.txt";
    NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(null, username, password);
    file = new SmbFile(url, auth);
    try (SmbFileInputStream in = new SmbFileInputStream(file)) {
        int bytesRead = 0;
        do {
            bytesRead = in.read(buffer)
            // here you have "bytesRead" in buffer array
        } 
        while (bytesRead > 0);
    }
} catch(Exception e) {
    JOptionPane.showMessageDialog(null, "ERROR: "+e);
}

or even better, assuming that you're working with text files - using BufferedReader from Java SDK:

try (BufferedReader reader = new BufferedReader(new InputStreamReader(new SmbFileInputStream(file)))) {
    String line = reader.readLine();
    while (line != null) {
        line = reader.readLine();
    }
}

And write with:

try (BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(new SmbFileOutputStream(file)))) {
    String toWrite = "xxxxx";
    writer.write(toWrite, 0, toWrite.length());
}

Java JCIFS how right to copy file from Samba to Windows local?

option resolve to the problem

    InputStream in = null;
               OutputStream out = null;
               try{

                   String SambaURL= "smb://usersamba:1234@192.168.1.110/data/1b.csv";
                   File destinationFolder = new File("C:\\Temp\\IN\\");
                   SimpleDateFormat fmt = new SimpleDateFormat("yyyyMMddHHmmssSSS_");
                   File child = new File (destinationFolder+ "/" + fmt.format(new Date()) +"1b.csv");
                   SmbFile dir = new SmbFile(SambaURL);
                   SmbFile fileToGet=new SmbFile(SambaURL);
                   fileToGet.connect();

                   in = new BufferedInputStream(new SmbFileInputStream(fileToGet));
                   out = new BufferedOutputStream(new FileOutputStream(child));

                   byte[] buffer = new byte[4096];
                   int len = 0; //Read length
                   while ((len = in.read(buffer, 0, buffer.length)) != -1) {
                             out.write(buffer, 0, len);
                   }
                   out.flush(); //The refresh buffer output stream
               }
               catch (Exception e) {
                   String msg = "The error occurred: " + e.getLocalizedMessage();
                   System.out.println(msg);
               }
               finally {
                   try {
                       if(out != null) {
                           out.close();
                       }
                       if(in != null) {
                           in.close();
                       }
                   }
                   catch (Exception e) {}
               }

Write/upload a file using Samba/JCIFS issue (SmbAuthException: Access is denied)

OMG!!! Solution was so simple!!! To access network which is not login/password protected and thus doesn't need any authorization is not NtlmPasswordAuthentication.ANONYMOUS BUT it is:

NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(null, null, null);

damn it wasn't that obvious!

How to copy file from smb share to local drive using jcifs in Java?

maybe adding auth to the second file:

SmbFile dest = new SmbFile ("C:/SQLRESTORESTAGE/v2.bak",**auth**);

using SmbFile dest = new SmbFile ("C:/SQLRESTORESTAGE",auth).canWrite
you know if you have write permissions on the parent directory
