TransactionAwareConnectionFactoryProxy

Class Overview

Proxy for a target CCI javax.resource.cci.ConnectionFactory, adding awareness of Spring-managed transactions. Similar to a transactional JNDI ConnectionFactory as provided by a J2EE server.

Data access code that should remain unaware of Spring's data access support can work with this proxy to seamlessly participate in Spring-managed transactions. Note that the transaction manager, for example the CciLocalTransactionManager, still needs to work with underlying ConnectionFactory, not with this proxy.

Make sure that TransactionAwareConnectionFactoryProxy is the outermost ConnectionFactory of a chain of ConnectionFactory proxies/adapters. TransactionAwareConnectionFactoryProxy can delegate either directly to the target connection pool or to some intermediate proxy/adapter like ConnectionSpecConnectionFactoryAdapter.

Delegates to ConnectionFactoryUtils for automatically participating in thread-bound transactions, for example managed by CciLocalTransactionManager. getConnection calls and close calls on returned Connections will behave properly within a transaction, i.e. always operate on the transactional Connection. If not within a transaction, normal ConnectionFactory behavior applies.

This proxy allows data access code to work with the plain JCA CCI API and still participate in Spring-managed transactions, similar to CCI code in a J2EE/JTA environment. However, if possible, use Spring's ConnectionFactoryUtils, CciTemplate or CCI operation objects to get transaction participation even without a proxy for the target ConnectionFactory, avoiding the need to define such a proxy in the first place.

NOTE: This ConnectionFactory proxy needs to return wrapped Connections in order to handle close calls properly. Therefore, the returned Connections cannot be cast to a native CCI Connection type or to a connection pool implementation type.
