You can not load a properties file inside a jar as following way..
Properties props = new Properties();
props.load(new FileInputStream("conf.properties"));
In this case you have to use
Properties props = new Properties();
InputStream in = this.getClass().getClassLoader().getResourceAsStream("conf.properties");
props.load(in);
I hope this will help you. For any other query you can post question as comment.
