NullPointerException when reading a properties file in Java

Question

I am using the following code to read a properties file:

Properties pro = new Properties();
InputStream is = Thread.currentThread().getContextClassLoader().         


        

Answer 1

I had the same problem and this helped me:

InputStream is;
try {

    is = this.getClass().getClassLoader().getResourceAsStream("config.properties");

    prop.load(is);

    String url = prop.getProperty("url");
    String user = prop.getProperty("user");
    String pass = prop.getProperty("password");
    is.close();
    // opening database connection to MySQL server
    con = DriverManager.getConnection(url, user, pass);

} catch (FileNotFoundException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
} catch (SQLException e) {
    e.printStackTrace();
}
