OJB does connection pooling per default, expect for datasources. Datasources never will be pooled. Responsible for managing the connections in OJB are implementations of the org.apache.ojb.broker.accesslayer.ConnectionFactory.java interface. There are several implementations shipped with OJB called org.apache.ojb.broker.accesslayer.ConnectionFactoryXXXImpl.java . You can find among other things a none pooling implementation and a implementation using jakarta-DBCP api. To manage the connection pooling define in your jdbc-connection-descriptor a connection-pool element. Here you can specify which ConnectionFactory implementation should be used. More info see repository section or repository.dtd .
