Integrating voice / video communication into business processes can accelerate resolution time, reduce mistakes, and establish a full audit-trail of the interactions. Some VoIP service providers offer website based or plugin based solutions, which are, however, difficult to integrate with other applications. A promising approach to overcome these disadvantages is the development of appropriate Web...
In this paper, we propose an approach to simulation and validation of Web services choreography described by WS-CDL. Simulation of Web services choreography is important to analyze and test the choreography model written by SOA designers. On the other hand, CDL specification regulates the correct behaviors a CDL program has to obey. Thus, constraints are specified in CDL specification including static,...
The veracity of the decision in the perishable goods retail is partly relied on the accurate and rapid real time data. Combined with the mobile technologies an information system based on SOA is built to manage the data. The Smart phone is used to collect, exchange and display the information. To be collected the data, the barcode scanner and the barcode identification software which are planted in...
In service oriented architecture (SOA) environment, the communication and infrastructure security is crucial. The most important specification addressing Web services security is WS-Security, which collaborates with the SOAP message specifications, providing integrity, confidentiality and authentication for Web services. However, WS-Security focuses SOAP message security between trusted partners....
An example is given to analyze its security flaws and security requirements in the services oriented architecture. Aimed at the increasingly severe security of SOA, a model for building end to end security services is proposed, the specification concerned with Web services message-level security is put forward, such as WS-security and SAML, according to these specifications, the design and realization...
Web service security is one of the important areas of research both in industry as well as in academia. SOAP messages with XML signatures under Web service security specification provide secure message exchange solutions in SOA based applications. Recent researches established that the solutions based on the specification have several limitations. XML rewriting attacks on SOAP messages exposed the...
This paper accomplishes the automatic composition of web services by leveraging semantics in XML Schemas, and by automatically generating aligned ontologies from mappings between XML schemas. Hence, we propose to encode the import of schemas and their mappings in HTML, which when combined with JavaScript libraries enable a web user to write mashups that hide coding and ontological complexities and...
