Połączenie nie może być puste, gdy nie ustawiono 'hibernate.dialect'

więcej problemów z konfiguracją hibernacji z spring3. tym razem mówi się, że połączenie jest zerowe, ponieważ dialekt nie jest ustawiony, co jest w moim pliku hibernate.cfg.xml.

Oto pełny wyjątek:

    org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mySessionFactory' defined in URL [file:war/WEB-INF/datasource-config.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Connection cannot be null when 'hibernate.dialect' not set

Oto mój plik dataSource-config.xml, który ustawia zakład sesji

    <?xml version="1.0" encoding="UTF-8"?>

Poniżej znajduje się plik hibernate.cfg.xml

 <?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

    <session-factory>
        <!-- JDBC connection settings -->
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/freedom</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password">password</property>

        <!-- JDBC connection pool, use Hibernate internal connection pool -->
        <property name="connection.pool_size">25</property>

        <!-- Defines the SQL dialect used in Hiberante's application -->
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>

        <!-- Enable Hibernate's automatic session context management -->
        <property name="current_session_context_class">thread</property>

        <!-- Disable the second-level cache  -->
        <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

        <!-- Display and format all executed SQL to stdout -->
        <property name="show_sql">true</property>
        <property name="format_sql">true</property>

        <!-- Drop and re-create the database schema on startup -->
        <property name="hbm2ddl.auto">create</property>

        <!-- Mapping to hibernate mapping files -->
        <!--mapping resource="org/kodejava/example/hibernate/app/Label.hbm.xml"/-->
    </session-factory>
</hibernate-configuration>

Jak widać, dialekt jest ustawiany.

edit: mój plik database.properties

    # DB properties file

database.url=jdbc:mysql://localhost:3306/freedom
database.driver=com.mysql.jdbc.Driver
database.user=root
database.password=password
database.maxConnections=25

edit: tutaj jest ślad pełnego stosu. dostęp do bazy danych może być problemem, ale mogę uzyskać dostęp do niego za pomocą wiersza polecenia?
