Utilizing cross-domain SOAP Web services using client-side languages in an enterprise mashup platform

Service oriented architectures (SOA) based on Simple Object Access Protocol (SOAP) Web services have attracted the attention of enterprises mainly for business-to-business integration and to create composite applications that execute business processes. An existing problem is the lack of preoccupation with non technical users due to the fact that to create a composite application to fulfill users needs, it is necessary to be in contact with IT staff. To overcome this issue, enterprises can take advantage of web 2.0, 'introducing in the development stage some technologies like mashups and some concepts like user empowerment, collaborative work and collective intelligence. Some results [3] [13] have shown how web 2.0 concepts can help non technical users to produce relative complex business processes. However, traditional enterprise requirements goes beyond typical web 2.0 solutions in several aspects: (1) traditional enterprise systems are based on heterogeneous stack of technologies that are not directly exploitable from a web-based client (where SOAP web services play an important role); (2) web browsers set some cross-domain security constraints making difficult to integrate services from diverse domains. In this paper, a contribution to two web 2.0 research projects [14] [15] partially solves the problems described: provide a way to invoke cross-domain backend services (based on SOAP technologies) directly only using clientside languages, without a need for any adaptation layer. © 2010 ACM.

Arquitetura Orientada a Serviços baseada na Tecnologia Jini: um caso de teste em Computação Ubíqua

T he people’s daily lives are surrounded by computing devices, with increasing resources (sensors) and, with increasing processing. How these devices communicate is still not natural and This retards the growth of Ubiquitous Computing. This paper presents a way in which these devices can communicate using Jini technology and concepts of Service Oriented Architecture, applying these concepts in a test case of Ubiquitous Computing. To conduct the test case was constructed a fictitious system for management of a soccer championship, where users can interact with each other and with the system in a simplified way, have access to data in real time of the championship during the event. This communication is performed by services built using Jini technology, which were based on key SOA concepts, such as modularity and reusability
