Java and MariaDB connection drivers errors

Question

I can connect Java and Maria DB with JDBC and DriverManager. It works. I can write line in my database's tables ect.... But with "BASIC DATA SOURCE" i can't connect to MariaDB. I use openJDK 15 on FEDORA. I don't understand why i can't connect to database.

This is my code :

    public static void main(String... args){
        
        Connection conn = null;
        try {
            long identifiant = 24L;
            String nom = "Errani";
            String prenom = "Sara"; 
            //data for connection with DB
            String userName = "kent1";
            String password= "*****";
    
            BasicDataSource dataSource = new BasicDataSource();
            
            conn = dataSource.getConnection();
            dataSource.setUrl("jdbc:mariadb://localhost:3306/TENNIS");
            dataSource.setUsername(userName);
            dataSource.setPassword(password);
            //conn = DriverManager.getConnection("jdbc:mariadb://localhost:3306/TENNIS?useSSL=false&useLegacyDatetimeCode=false&serverTimezone=Europe/Paris","kent1","*****");
            //conn.setAutoCommit(false);
            
            
            PreparedStatement preparedStatement = conn.prepareStatement("UPDATE JOUEUR SET NOM=?, PRENOM=? WHERE ID=?");
            
            preparedStatement.setString(1, nom);
            preparedStatement.setString(2,  prenom);
            preparedStatement.setLong(3, identifiant);
           
            
            int nombreEnregistrementModifies = preparedStatement.executeUpdate();
            System.out.println("Le nombre d'enregistrement modifié est : "+nombreEnregistrementModifies);
            System.out.println("success");
            
            //conn.commit();
            
        } catch (SQLException e) {
            e.printStackTrace();
        }
        finally {
            try {
                if (conn!=null) {
                    conn.close();
                }
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
    }

And this is my error when i RUN my code :

java.sql.SQLException: Cannot create JDBC driver of class '' for connect URL 'null'
    at org.apache.commons.dbcp2.DriverFactory.createDriver(DriverFactory.java:75)
    at org.apache.commons.dbcp2.BasicDataSource.createConnectionFactory(BasicDataSource.java:462)

and this is my pom.xml with Maven and my dependencies for MariaDB connector and DBCP

  
  <dependencies>
<!-- https://mvnrepository.com/artifact/org.mariadb.jdbc/mariadb-java-client -->
<dependency>
    <groupId>org.mariadb.jdbc</groupId>

Answer 1

I have solution.... In fact, i should put the conn = dataSource.getConnection(); after the userName and userPassword..... So my code seems like that now :

        dataSource.setUrl("jdbc:mariadb://localhost:3306/TENNIS");
        dataSource.setUsername(userName);
        dataSource.setPassword(password);
        //conn = DriverManager.getConnection("jdbc:mariadb://localhost:3306/TENNIS?useSSL=false&useLegacyDatetimeCode=false&serverTimezone=Europe/Paris","kent1","*****");
        //conn.setAutoCommit(false);
        
 conn = dataSource.getConnection();
        
        PreparedStatement preparedStatement = conn.prepareStatement("UPDATE JOUEUR SET NOM=?, PRENOM=? WHERE ID=?");

It works !
