Enabling transactional composites services
Web services do not limit themselves into e-business and information delivery; their scope is much wider than that through offering services to businesses and individual customers. Aiming to provide new business functions, it is important that inter-organisational information systems are effectively integrated. These services should display availability, scalability and adaptability in order to ensure fast processing even under dynamically changing scenarios. A single organisation may offer basic services whose wide variety over the Internet may lead to new business opportunities by composing multiple basic services into new composite ones. Urged by this the ADAPT project focused on advancing middleware technologies that would support web services that are adaptive and capable of being easily composed. Towards this goal suitable technology and software infrastructure was developed for specifying, enacting and monitoring inter-enterprise business processes. Part of project work involved the realisation of the Java Advanced tranSaction Support (JASS) tool. This is a Java implementation of two standards for advanced transaction processing. One of the standards is the Java Platform Enterprise Edition (J2EE) Activity Service Java Specification Request (JSR) 095 from Java Community Process (JCP). This activity offers a core service for handling and propagating transactional contexts. Moreover, it supports the implementation of advanced transactional models on top of this core service without retaining resources during the transaction processing. The second standard that was implemented was the OASIS Web Service Composite Application Framework (WS-CAF). OASIS (Organisation for the Advancement of Structured Information Standards) is an international consortium for developing data representation standards for computer software. The standard comprises of three specifications, namely WS-Context, WS-Coordination and WS-Transaction. The JASS tool is currently a pre-industrial product that can be easily turned into a commercial one. Collaborations are sought with partners interested in commercially exploiting the result or its industrial usage. Consultancy is offered on its use and application.
