log4j2 JDBC manager не может подключиться к базе данных

Я пытаюсь настроить log4j v2 с mysql, но он возвращает эту ошибку: 

2014-08-01 15:35:24,819 ERROR Unable to write to database [jdbcManager{ description=databaseAppender, bufferSize=0, connectionSource=factory{ public static java.sql.Connection it.prisma.presentationlayer.webui.ConnectionFactory.getDatabaseConnection() }, tableName=logs, columns=[ { name=message, layout=%message, literal=null, timestamp=false } ] }] for appender [databaseAppender]. org.apache.logging.log4j.core.appender.AppenderLoggingException: Cannot write logging event or flush buffer; JDBC manager cannot connect to the database.

Caused by: java.sql.SQLException: Failed to obtain connection from factory method.

Caused by: java.sql.SQLException: No suitable driver found for jdbc:mysql://10.41.1.68:3306/test

Моя конфигурация аналогична doc , с той лишь разницей, что: 

new PoolableConnectionFactory(connectionFactory, pool, null, "SELECT 1", false, false, Connection.TRANSACTION_READ_COMMITTED);

Я думаю, что мой tomcat7 хорошо настроен, потому что я могу войти с log4j v1.

ОК решение таково:

1-создание класса фабрики соединений

import java.sql.Connection;
import java.sql.SQLException;
import java.util.Properties;

import javax.sql.DataSource;

import org.apache.commons.dbcp.DriverManagerConnectionFactory;
import org.apache.commons.dbcp.PoolableConnection;
import org.apache.commons.dbcp.PoolableConnectionFactory;
import org.apache.commons.dbcp.PoolingDataSource;
import org.apache.commons.pool.impl.GenericObjectPool;


public class ConnectionFactory {

    private static interface Singleton {
        final ConnectionFactory INSTANCE = new ConnectionFactory();
    }

    private final DataSource dataSource;

    private ConnectionFactory() {

        try {
            Class.forName("com.mysql.jdbc.Driver");
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
            System.exit(0);
        }

        Properties properties = new Properties();
        properties.setProperty("user", "root");
        properties.setProperty("password", "root");

        GenericObjectPool<PoolableConnection> pool = new GenericObjectPool<PoolableConnection>();
        DriverManagerConnectionFactory connectionFactory = new DriverManagerConnectionFactory(
                "jdbc:mysql://example.org:3306/exampleDb", properties
        );
        new PoolableConnectionFactory(connectionFactory, pool, null, "SELECT 1", 3, false, false, Connection.TRANSACTION_READ_COMMITTED);
        this.dataSource = new PoolingDataSource(pool);
    }

    public static Connection getDatabaseConnection() throws SQLException {
        return Singleton.INSTANCE.dataSource.getConnection();
    }
}

2-создайте файл конфигурации в src / main / resources с именем log4j2.xml 

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="TRACE" monitorInterval="30">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />
        </Console>
        <JDBC name="databaseAppender" tableName="logs">
            <ConnectionFactory class="my.pack.ConnectionFactory"
                method="getDatabaseConnection" />
            <!-- <Column name="id" literal="LOGGING.APPLICATION_LOG_SEQUENCE.NEXTVAL" /> -->
            <Column name="date" isEventTimestamp="true" />
            <Column name="level" pattern="%level" />
            <Column name="message" pattern="%message" />
            <Column name="class" pattern="%class" /> 
        </JDBC>
    </Appenders>
    <Loggers>
        <Root level="trace">
            <AppenderRef ref="Console" />
            <AppenderRef ref="databaseAppender" />
        </Root>
    </Loggers>
</Configuration>

3-создайте таблицу, подобную этой: Введите описание изображения здесь

4-Добавить mysql connector к {tomcat}/bin
