  31                   ========================================

  33                   and also org.springframework.orm.hibernate3.AbstractSessionFactoryBean.setDataSource(DataSource dataSource)
  34
  35                   IMPORTANT:
  36                   Because of the constraint (1) the org.hibernate.connection.C3P0ConnectionProvider anc not be used
  37                   for the cdm library because it requires the dataSource bean in some cases.
  38
  39                                           (1)
  40                                           Do NOT specify the dataSource in the sessionFactory for example in the
  41                                           org.springframework.orm.hibernate4.LocalSessionFactoryBean
  42                                           !!!==> If *dataSource* is set, this will override corresponding settings in Hibernate properties.!!!
  43                                                   If this is set, the Hibernate settings should not define a connection provider to
  44                                               avoid meaningless double configuration.
  45                                           (2)
  46                                           Hibernate uses the hibernate.c3p0.max_size property to determine if c3p0
  47                           is begin used.  Therefore the max_size property MUST be set. - maybe not need in hibernate 3.4 +
  48                           (3) If you are using Hibernate's C3P0ConnectionProvider you must set the following properties
  49                           in your hibernate configuration, using hibernate-specific configuration keys.
  50                           All other properties must be defined as usual in a c3p0.properties file.
  51                           This is confusing, and will hopefully be simplified some time in the future, but for now...

  53                           DOUMENTATION UPDATE (2015-05-22):
  54                           Hibernate's C3P0ConnectionProvider renames 7 c3p0 configuration properties, which,
  55                           if set in your hibernate configuration, will override any configuration you may have set
  56                           in a c3p0.properties file.
  57                           TODO: are points (2) and (3) still valid? I don't think so! (AK)
