Building a Service-Oriented ERP from an Open Source Software

The opening and the interconnection of the enterprise information systems, added to the unceasingly increasing changes of the software environments, involve the development (designing) of flexible, interoperable and distributed applications. Thus the existing software systems must evolve to conform to these requirements. The model which currently address this kind of concern is SOA (service oriented architecture). This article deals with the reuse of ADempiere within the framework of the implementation of a service oriented ERP. To operate the migration of the existing code, firstly we reconstituted the architecture of this ERP. This operation made it possible to acquire the technical knowledge necessary to develop services by injection of dependence. The new software resulting from this operation distinctly separates the presentation tier from the back-end. The back-end tier exposes a set of Web services which encapsulates the code of ADempiere. These services can either be in a synchronous way throughout the Spring XFire technology, or in an asynchronous way through Apache ActiveMQ technology.
