I started writing a little junit testcase to play around with hibernate, but apparently I dont event manage to create a proper session.

I have the MySQL driver jar in my class path, yet it fails to load.

Can anyone see any faults in my setup ?

HIBERNATE.CFG.XML

Code:
<hibernate-configuration>

    <session-factory>
   
      <property name="dialect">net.sf.hibernate.dialect.MySQLDialect</property>
       <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
      <property name="hibernate.connection.url">jdbc:mysql://localhost</property>
      <property name="hibernate.connection.username">torque</property>
      <property name="hibernate.connection.password">torque</property>
      <property name="hibernate.dialect">net.sf.hibernate.dialect.MySQLDialect</property>
      <property name="hibernate.show_sql">true</property>
      <property name="hibernate.connection.pool_size">20</property>

        <mapping resource="com/bluprinted/blagmodel/Consumer.hbm.xml"/>

    </session-factory>

WHAT I TRY TO DO, BUT NEVER GET TO


Code:
   public void testConsumer() throws HibernateException {
      Session session = currentSession();

      Transaction tx= session.beginTransaction();

      Consumer joe = new Consumer();
      joe.setFirstName("Joe");
      joe.setSurname("Schmoe");

      session.save(joe);
      tx.commit();

      closeSession();
      
   }

Just out of interest - why is your dialect stated twice?

Are you sure the url is correct: jdbc:mysql://localhost I'm not that familiar with MySQL but don't you need to specify a db?

Also make 100% sure that the library is being included in the classpath. Use ant -versbose to execute the ant task - this should generate the classpath.

Was just trying different properties, hoping it might make a difference

You were right, I needed to specify the database, works now it seems, thanks.
