Java无法从Linux在Windows共享文件夹中创建文件

Question

I am trying to create a file in a shared folder using the below code. I am able to do it when i run this code on windows. But however when i run the same code on linux it is not working.

In liunx it is creating a file named "\\192.168.1.102\\share\\1.pdf" in the folder where i run this java code instead of creating a file 1.pdf in the shared folder "\\192.168.1.102\\share\\".

It seems like while running on Linux the server was not identifying the path as a shared location, Instead it reads that as it's local path.

Are there any other ways to create a file in the shared folder? Could anyone please help me in resolving this?

public class Test {

    public static void main(String args[]) {

        String s1 ="\\\\192.168.1.102\\share";
        try{

            FileOutputStream fos = new FileOutputStream(s1+"\\1.pdf");
            fos.write(("Testing Success").getBytes());
            fos.close();
        }
        catch(Exception e){
            e.printStackTrace();
            System.out.println(e.toString());
        }

        File file = new File(s1);
        System.out.println(file.exists());
    }
}

Answer 1

Linux simply doesn't support \\\\ip\\folder path syntax.

You have to mount you shared folder before use.

Answer 2

Check if you have enough permissions to write file on the shared folder. Or try running Jar of your code as administrator.

Answer 3

(1) Please use java function File.separator instead of "\\" in file path to make it platform independent.

As Windows support "\\\\" and linux supports "/".

(2) Check you have permission to write on that directory by using chmod command.

Answer 4

Assuming the file-system is properly mounted in the path you're using, the code won't work cross-platform because paths in Windows use \\ as a segment separator, while paths in Linux use / .

You should use cross-platform code to generate paths. The File class has a static String member called separator that will have the correct value for the platform.

String myPath = File.separator + "home" + File.separator + "bob"

The above will produce \\home\\bob in Windows, /home/bob in Linux/OSX
