Automatic generation of SOAs for Business Process execution: A vision based on models

Business Process Management (BPM) promotes in organizations a horizontal vision based on the processes they perform to reach their objectives, and on the systems that support them. These systems are "aware" of the business processes they integrate, which guide the system execution (Process Aware Information Systems, PAIS). Automating pieces of these processes by means of services orchestration (mainly web services) allows to integrate to process execution the invocation of legacy systems, systems from other organizations (clients, providers, partners, etc.) and newly developed systems. In this article we present a proposal for the automatic generation of this kind of systems to support business processes with services. The proposal is based on models and transformations between them, from the specification of the business process model in BPMN2, through the services model in SoaML, to the code generated for invoking services from process execution. In particular, the paper provides details on the generation of code in Java EE and Web Services.
