Cannot find symbol: MariaDbPoolDataSource

DriverManager.getConnection works perfectly. Way better performance than old mysql driver

But I am struggling with your pool code example:

https://mariadb.com/kb/en/pool-datasource-implementation/

MariaDbPoolDataSource pool = new MariaDbPoolDataSource("jdbc:mariadb://server/db?user=myUser&maxPoolSize=10");

try (Connection connection = pool.getConnection()) {
try (Statement stmt = connection.createStatement())

{ ResultSet rs = stmt.executeQuery("SELECT CONNECTION_ID()"); rs.next(); System.out.println(rs.getLong(1)); //4489 }

}

I have these imports:
import java.sql.*;
import javax.sql.*;

I compile as normal, but get this error:

javac select_con_mdb_ds_pool.java
select_con_mdb_ds_pool.java:46: error: cannot find symbol
MariaDbPoolDataSource pool = new MariaDbPoolDataSource("jdbc:mariadb://192.168.1.155?user=xxx&password=yy&maxPoolSize=10");

2 errors

I'm probably doing something stupid - any help would be appreciated!
