Linux Write File Exception In Java Code

Here is My WriteFile

WriteFile.writeFile(str, "./test/my.html");

And writeFile() method code

public static void writeFile(String content, String fileName)
  {
    try
    {
      File file = new File(fileName);
      if (!file.exists()) {
        file.createNewFile();
      }
      FileWriter fw = new FileWriter(file.getAbsoluteFile());
      BufferedWriter bw = new BufferedWriter(fw);
      bw.write(content);
      bw.close();
    }
    catch (IOException e)
    {
      e.printStackTrace();
    }
  }

This Code Working fine With Windows but in Linux I am getting below exception

java.io.IOException: No such file or directory

    at java.io.File.createNewFile(File.java:1006)
