Ubuntu – Java Gmail API – Reading credentials from json file using Inputstream vs BufferedReader

Im trying to run my java application on Ubuntu server. I enter absolute path to read that file but it produces and error.

The code which is supposed to read that file is below.

private static final String CREDENTIALS_FILE_PATH = "/home/dockeradmin/credentials.json";


InputStream in = application.class.getResourceAsStream(CREDENTIALS_FILE_PATH);
        if (in == null) {
            throw new FileNotFoundException("Resource not found: " + CREDENTIALS_FILE_PATH);
        }

And the error I get:

java.io.FileNotFoundException: Resource not found: /home/dockeradmin/credentials.json

When I tried to read file with same path using BufferedReader everything worked perfectly.

Like this:

BufferedReader br = new BufferedReader(new FileReader(new File("/home/dockeradmin/credentials.json")));

So my question is, what is the difference between these two and how could I solve my current problem?

    This line caused trouble.

    InputStream in = application.class.getResourceAsStream(CREDENTIALS_FILE_PATH);

    I fixed this by replacing that, with that

    InputStream in = new FileInputStream(CREDENTIALS_FILE_PATH);

    The reason of the error is that getResourceAsStream is used to locate file on classpath and it can’t be used for locating file on file system.
