Read file from remote machine using java io

Question

public static void main(String[] args) throws IOException, URISyntaxException {

    String ipaddress = "10.20.220.187";
    String folderpath = "C:\\Users\\Administrator\\Desktop\\KS_testData\\";
    String fileName = "test.txt";

    String inputFileName = "file:\\\\"+ipaddress+"\\"+folderpath+fileName;

    System.out.println(" inputFileName "+inputFileName);

    File file = new File(inputFileName);
    FileReader inputFileReader = new FileReader(file);
    BufferedReader inputStream = new BufferedReader(inputFileReader);

    String inLine = null;
    while ((inLine = inputStream.readLine()) != null) {
        System.out.println(inLine);
    }
}

Here Im trying to connect to provided ipaddress and read file on it, The specified folder name is a Shared Folder and Im getting FileNotFoundException. Can anyone suggest what Im doing wrong.

Output received is :

    inputFileName file:\\10.20.220.187\C:\Users\Administrator\Desktop\KS_testData\test.txt
Exception in thread "main" java.io.FileNotFoundException: file:\10.20.220.187\C:\Users\Administrator\Desktop\KS_testData\test.txt (The filename, directory name, or volume label syntax is incorrect)

If you paste `file:\10.20.220.187\C:\Users\Administrator\Desktop\KS_testData\test.txt` into your file explorer, does the file exist (with this exact path)? — achAmháin, May 22 '18 at 07:50
You can not read a file from a different computer using `file:\\`. This might help you https://stackoverflow.com/questions/2011264/how-to-read-a-file-from-remote-system-using-java?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa — RP-, May 22 '18 at 07:53

String inputFileName = "file:\\\\"+ipaddress+"\\"+folderpath+fileName;

The problem is here. This is not a filename, it is a URL.

Get rid of the file: part.

No luck, even after removing file: – KDS May 22 '18 at 11:48

@KDS Define 'no luck'. This is not a technical term or error message with which I am familiar. – user207421 May 23 '18 at 04:57

Try with this jcifs library

SmbFile fileToRead= new SmbFile(smb://192.168.0.27/export/myFile.txt);

Hope this would help,

The `http:` protocol does not work unless there is an HTTP server, and it does not include drive names in the URL path. – user207421 May 22 '18 at 10:54
That is absolutely true. :) – Kovacic May 22 '18 at 13:08
@Kovacic thanx. i used jcifs. it worked fine. – KDS May 23 '18 at 13:52
Glad I could help. – Kovacic May 23 '18 at 14:15
