javax.resource.cci
Interface LocalTransaction

public interface LocalTransaction

The LocalTransaction defines a transaction demarcation interface for resource manager local transactions. Note that this interface is used for application level local transaction demarcation. The system contract level LocalTransaction interface (as defined in the javax.resource.spi package) is used by the container for local transaction management.

A local transaction is managed internal to a resource manager. There is no external transaction manager involved in the coordination of such transactions.

A CCI implementation can (but is not required to) implement the LocalTransaction interface. If the LocalTransaction interface is supported by a CCI implementation, then the method Connection.getLocalTransaction should return a LocalTransaction instance. A component can then use the returned LocalTransaction to demarcate a resource manager local transaction (associated with the Connection instance) on the underlying EIS instance.
