Direct Known Subclasses:

TransactionAwareDataSourceConnectionFactory

public class LocalDataSourceConnectionFactory

extends org.apache.ojb.broker.accesslayer.ConnectionFactoryManagedImpl

OJB connection factory that delegates to Spring-managed DataSource beans.

Define the following entry in your OJB.properties to use this connection factory:

 ConnectionFactoryClass=org.springframework.orm.ojb.support.LocalDataSourceConnectionFactory

Interprets JCD aliases in OJB's JDBC connection descriptors as Spring bean names. For example, the following will delegate to the Spring bean named "myDataSource":

 <jdbc-connection-descriptor jcd-alias="myDataSource" default-connection="true" useAutoCommit="1"/>

Depends on LocalOjbConfigurer being defined as Spring bean, which will expose the Spring BeanFactory to the corresponding static field of this connection factory.

Consider using the subclass TransactionAwareDataSourceConnectionFactory instead, to let Spring's OJB access to participate in JDBC-based transactions managed outside of OJB (for example, by Spring's DataSourceTransactionManager), or to automatically apply transaction timeouts managed by PersistenceBrokerTransactionManager.
