Abstraction of Transaction Demarcation in Component-Oriented Platforms

Romain Rouvoy and Philippe Merle (INRIA)

Component-oriented middleware becomes the privileged substrate for distributed computing in
heterogeneous and open environments.Technically they promote the notion of container as
structure to host application components. They transparently take charge of a large set of technical
or non-functional services like security or transactions. The transaction service is integrated using
a set of transaction demarcation (TD) policies. Nevertheless, they are strongly linked to a specific
transactional monitor and they are not often isolated. The main contribution of this paper is to
propose a component-based framework to deal with TD policies. Thus, this framework allows one to
instantiate several configurations of TD policies with different platforms like EJB, CCM, OSGi,
WebServices and several transaction monitors like JTS, OTS, WS-T, BTP, etc. It proposes an
extensible abstraction of TD policies. This framework shows that no performance degradation are
introduced by the refactoring process.
