The recent developments in the scope of Web 2.0 highlight the benefits of exchanging users' experiences and turn the focus onto collaborative working. E-Learning ecosystems and CSCW systems should aim to provide as many functionalities as needed from users in order to act as a centralized interface for their collaborative learning and daily work. Since more and more functionalities are made available as webservices, these can be adapted into a collaborative system. In contemporary collaborative systems, however, such an adaption is often a challenge.Service oriented architectures (SOAs) facilitate the adaption and linking of webservices and build an ideal platform for new e-Learning ecosystems and CSCW systems. This paper presents the key aspects of turning the established CSCW system open-sTeam into a service oriented architecture (SOA). Our new flexible Wasabi framework, based on EJB 3 and JBoss, results in the next level of e-Learning ecosystems and CSCW enterprise architectures which is highly adaptable due to the support of webservices.
