Answer 1

Now I get it, somewhat answers here & there do help in getting me to the goal. Did a short edit to my code & it worked. Hope it'll also help some poor souls out there.

BufferedReader reader = new BufferedReader(new FileReader(filePath + "/src/DBTextFiles/Administrator.txt"));

try
{                           
    String line = null;         
    while ((line = reader.readLine()) != null)
    {
        if (!(line.startsWith("*")))
        {
            System.out.println(line);
        }
    }               
}
catch (IOException ex)
{
    ex.printStackTrace();
}               

finally
{
    reader.close();
}                   

Answer 2

This is a valid absolute path (on the systems I'm aware of):

    /path/to/directory/../../otherfolder/etc/

So what the other answer was saying, was to get the path to the current directory with:

    String filePath = new File("").getAbsolutePath();

Then concatenate your relative path with:

    filePath.concat("path to the property file");

Answer 3

This is not correct:

new FileReader(getClass().getResourceAsStream ("/DBTextFiles/Administrator.txt"))

You want:

new InputStreamReader(getClass().getResourceAsStream ("/DBTextFiles/Administrator.txt"))

Answer 4

In almost all cases you should use the portable forward slash "/"." In every case you should use either the File constructor that accepts a File (parent) & String (file name) or use System.getProperty("file.separator").
