Due to the autonomy, heterogeneity and continuous evolution of Web services, mediators are usually needed to support service interactions to overcome possible mismatches that may exist among business processes. In this paper, we introduce a space-based architecture for process mediator which considers both control-flow and data-flow, present possible mismatch patterns, and suggest how they can be automatically mediated. Our work can be used to perform runtime mediation and thus to facilitate service interactions.","PeriodicalId":275591,"journal":{"name":"2008 IEEE International Conference on Web Services","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123169404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Until recently, it was difficult to build a SOA based grid/distributed system using Web services due to the inability to learn the state of services. The state of a Web service could only be accessed through specialized clients and/or services. Should the specialized client or service fail, the state can't be accessed. This paper shows the innovative resources via Web instances (RVWI) framework. RVWI grants to web services the ability to show the state of dynamic resources in their WSDL. This was achieved via software components called connectors which watch for any changes in a resource and updates the web service. The significance of this report is the support for resources which can change state between requests and the innovation is the improvement of state updates between the service and discovery services.","PeriodicalId":275591,"journal":{"name":"2008 IEEE International Conference on Web Services","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115819594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Organizations frequently use many services, each with its own access control policies, which must interoperate while maintaining secure access to information. The integration problem is to take the set of such services and to find a globally consistent access control policy that ensures that the system composed from the services does not have any authorization failures or information disclosures. We give a sound and complete algorithm for access control integration by reducing the problem to Boolean constraint solving. We have implemented ROLEMATCHER, a tool to infer global role-based access control schemas for a set of services, and show on examples that it can quickly infer global roles for composed systems, or determine the absence of a globally consistent role schema.","PeriodicalId":275591,"journal":{"name":"2008 IEEE International Conference on Web Services","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124997247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As composite Web services are often long-running, loosely coupled and cross-organizational applications, advanced transactional support is required to ensure reliable execution. In addition, in the presence of multiple Web services with equivalent functionality, users will discriminate the alternatives based on their quality of service (QoS). This paper address the issue of selecting and composing Web services not only according to their functional requirements but also to their transactional properties and QoS characteristics defined using a quality model. In this model, Web services are selected in a way that satisfies user preferences. These preferences are expressed as weights over QoS criterion and as risk level defining semantically the transactional requirements.","PeriodicalId":275591,"journal":{"name":"2008 IEEE International Conference on Web Services","volume":"159 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134218082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our goal is to increase the maximum throughput available on a system that has multiple dynamic content services while meeting different service time criteria for these services in dynamic workloads. Our challenge is to significantly improve response times for dynamic content on a busy well-tuned thread-pool-based system without prioritizing any specific services. Our experiments demonstrate that a prototype using our approach on J2EE middleware quickly (around every 20 ms) adjusted the thread counts for the services and that it improved the average 90th-percentile response times by up to 27% (and 22% on average) for the SPECjAppServer2004 benchmark.","PeriodicalId":275591,"journal":{"name":"2008 IEEE International Conference on Web Services","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134279548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach is based on the explicit distinction between NFP offered by providers and requested by users, on the concept of policy that aggregates NFP descriptions into single entities with an applicability condition, and finally on a set of constraint operators, which is particularly relevant for NFP requests. The semantic meta-model embracing the above perspective is defined by a BNF syntax whose semantics is formalized by an ontology. The ontology has been formalized in OWL-DL and WSML to provide for logical syntax. The logic upon which the meta-model supports NFP-based selection is discussed in the paper.","PeriodicalId":275591,"journal":{"name":"2008 IEEE International Conference on Web Services","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115785158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The intermediaries may add support services to the SOAP message exchange, such as routing, logging, and security. The typical processing by a SOAP intermediary is parsing the incoming SOAP messages, checking the data in each message, and then serializing the messages to put them back into the network. DOM is one of the popular interfaces to navigate an XML tree. Existing DOM implementations are not efficient for SOAP intermediary processing. Existing DOM implementations parse XML data to create tree data and traverse the tree data for serialization. Typically, a SOAP intermediary rarely modifies the tree data. In such situations, creating the tree data and serializing it back into XML data is computationally expensive. We propose a DOM implementation based on a hybrid data representation that uses both literal XML and DOM objects. In our implementation, a SOAP intermediary stores the original literal XML representation and reuses it to avoid traversing all of the tree data during serialization. We prototyped the DOM implementation and evaluated its performance.","PeriodicalId":275591,"journal":{"name":"2008 IEEE International Conference on Web Services","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123060036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
