folder not creating in linux through java program

Question

I am trying to create folder and write images in it from war using following code:

// war directory : /opt/apache-tomcat/webapps/mj.war

String absoluteDiskPath = "tmp/mjpics/images/travel_schedule";
File file = new File(absoluteDiskPath);
if (!file.exists()) {
    if (file.mkdir()) {
        System.out.println("Directory is created!");
        try {
            writeText(textcontent, textFileName, eventDate, eventCat, absoluteDiskPath+"\\"+eventCat+"\\"+eventName);
            writeImage(imagecontent, imageFileName, eventDate, eventCat, absoluteDiskPath+"\\"+eventCat+"\\"+eventName);
            imagecontent.close();
            textcontent.close();
            UplodedData.flush();
        } catch (IOException e) {
            e.printStackTrace();
            return false;
        }
        return true;
    } else {
        System.out.println("Failed to create directory!");
        return false;
    }
}

Ouput: Failed to create directory.

Add an exception block to check for the error message why is couldn't create the dir. Mostly a permissions issue — Harinder, Jan 02 '16 at 14:08

Your absoluteDiskPath isn't absolute. Not sure if that's intentional, but you are missing a slash in front of it. Also, I am guessing, you want .mkdirs instead of .mkdir. The plural form creates all the folders in the path, the singular will only create the last one, and fail if the rest of the path does not exist.

I.e., if you are trying to create a folder "foo/bar/baz", .mkdir will fail unless you already have a folder " foo" in your current directory, containing a folder named "bar" inside of it.

parent dirs are existing, i want to create travel_schedule only – Taufik Pirjade Jan 02 '16 at 14:14
Then I guess, it's the missing slash problem. You are trying to create this patn in your current directory, which is almost always wrong. – Dima Jan 02 '16 at 14:16
their are two different directories /tmp/mjpics and war is in another directories – Taufik Pirjade Jan 02 '16 at 14:21
This has nothing to do with where war is. – Dima Jan 02 '16 at 16:16
Worked for me String absoluteDiskPath = "/tmp/mjpics/images/travel_schedule" – Taufik Pirjade Jan 02 '16 at 16:55
