DriverClass implements java.sql.Driver. It is given in JDBC driver. In hibernate Programming we configure DriverClassName in hibernate-cfg.xml. Configuration file is given here-

<?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">
<hibernate-configuration>
    <session-factory>

        <!-- Database connection settings -->

        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.url">jdbc:mysql://localhost:3306/hibernate</property>
        <property name="connection.username">root</property>
        <property name="connection.password">root</property>
        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">1</property>

        <!-- SQL dialect -->

        <property name="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>
        <!-- Echo all executed SQL to stdout -->

        <property name="show_sql">true</property>

        <!-- Drop and re-create the database schema on startup -->
        <property name="hbm2ddl.auto">none</property>
        <mapping class="net.roseindia.table.Employee" />
    </session-factory>

</hibernate-configuration>

Description:- In configuration file first we set the connection -

driver_class is setting the driver name as-

<property name="connection.driver_class">com.mysql.jdbc.Driver
</property>

Setting the connection url as-

<property name="connection.url">jdbc:mysql://localhost:3306/hibernate</property>

Setting user name and password as-

<property name="connection.username">root</property>
        <property name="connection.password">root</property>
