Kan geen JDBC-verbinding maken

Dit kan je helpen

Voeg ook gebruikersnaam en wachtwoord toe

<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
   <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
   <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/sampleDB</property>
   <property name="hibernate.connection.username">yourUserNameForMysql</property>
   <property name="hibernate.connection.password">passwordForMySql</property>

Gebruik na Mysql 5.x de klasse org.hibernate.dialect.MySQL5Dialect

<property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>
   <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
   <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/sampleDB</property>
   <property name="hibernate.connection.username">yourUserNameForMysql</property>
   <property name="hibernate.connection.password">passwordForMySql</property>
