Hibernate (all versions) configuration using Spring (1.x and 2.x). When trying to invoke database autocompletion on hbm.xml file the error " No local DataSource found for configuration - dataSource property must be set on LocalSessionFactoryBean" happens. The root cause is because a new connection provider is being tried to be created with no proper datasource configured by Spring, instead of reuse the already (and properly) configured connection provider by Spring.
