Due to their long-duration and loosely coupled properties, Web service based applications require transactional support beyond traditional transactions. Some Web service standards have been proposed to deal with the transaction aspect of Web service applications. Compensation is a commonly used mechanism in these standards for backward recovery. However, the compensation mechanism usually adopted is too fixed and cannot satisfy the various requirements of different applications. In this paper, we first analyse the compensation protocol of current standards. Then we enrich the protocol by allowing flexible compensation and extend our proposed multiple-compensation mechanism in Web service environment. The implementation of the extended compensation mechanism is discussed and the incorporation of the mechanism into current standards is also addressed","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"85 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132736979","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}

It is supported by various modelling tools but so far no systems can directly execute BPMN models. The business process execution language for Web services (BPEL) on the other hand is a mainly block-structured language supported by several execution platforms. In the current setting, mapping BPMN models to BPEL code is a necessary step towards unified and standards-based business process development environments. It turns out that this mapping is challenging from a scientific viewpoint as BPMN and BPEL represent two fundamentally different classes of languages. Existing methods for mapping BPMN to BPEL impose limitations on the structure of the source model. This paper proposes a technique that overcomes these limitations. Beyond its direct relevance in the context of BPMN and BPEL, this technique addresses difficult problems that arise generally when translating between flow-based languages with parallelism","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"230 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121981474","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}

However, most of the XML-based applications, particularly the emerging Web services, suffer from low performance caused by XML processing and thus bring negative user experience in terms of response time. We argue that by reducing the considerable overhead in garbage collection the XML processing performance can be improved. We begin by conducting a set of experiments to understand the XML parser's memory characteristics, such as heap composition, object size and type distributions, object lifetime, and so on. Then, we get the valuable findings for improving performance that XML processing, which violates the weak generational hypothesis, is a memory allocation intensive workload in which most objects are small and long-lived. The findings can benefit the design of XML parsing specific GC and related tools designed to improve XML processing performance for Web services","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125477108","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}

Previous comparisons support the skeptics: Web services are shown to be significantly slower than RPC, and they lack features like automatic proxies. However, these studies are biased because they are based on an RPC communication style. Web services support a document-oriented style of communication that performs well even in the face of the high latency found in Internet or business transactions. We investigate these issues by comparing the design and implementation of a small file server application implemented using RMI and Web services. For this application, using the most straightforward implementation in both technologies, Web services outperform RMI when accessing multiple/deeply nested files, especially over high-latency channels. However, the default Web services interfaces are awkward to use, so we develop a technique for wrapping the Web service to make it as easy to use as the distributed object implementation. The same wrappers are then used to implement the document-oriented communication style in RMI, which improves performance but significantly complicates the design. This case study provides a more detailed comparison of the relationship between Web services and distributed objects","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130027964","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}

Therefore, the coordinator process is complex, less scalable, and bulky. This paper introduces an architecture and a technique for distributing the centralized coordination logic of traditional workflows by (i) extending the stateless Web services into self-coordinating entities using coordinator proxy objects, and (ii) creating a workflow over these entities by interconnecting them into a distributed network of objects using Web bond primitives. Previously, we have developed Web bond primitives to enforce interdependencies among autonomous entities.

(2005) is about building large-scale distributed applications by composing coarse-grained autonomous services in a flexible architecture that can adapt to changing business requirements. These services interact by exchanging one-way messages through standardized message processing and transport protocols. This vision is being driven by economic imperatives for integration and automation across administrative and organizational boundaries. This paper presents a concise yet expressive model for service contracts to describe messaging behavior. The idea is simple: we use Boolean conditions to specify when a message can be sent and received, where the conditions refer only to other messages in the service contract - that is, conditions only refer to a service's externalized messaging state and not to internal state","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114666838","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}

But their great drawback, the invocation overhead, has not been a research focus. So far, only invocations of simple Web services were considered. But Web service composition may create additional performance problems. Our measurements demonstrate that Web service composition may reduce the maximal load of a system drastically. The reduction quotient increases quasi-exponentially with the number of service compositions. We call that phenomenon \"service congestion\" since it is not due to the combined payload of the composed services. Such detrimental performance effects can not be tolerated in many areas. For that reason, we propose an optimized service composition architecture as a solution. This service component architecture uses service connectors on top of standard Web service middleware. It optimizes automatically the local invocation of services with a Lookup&Service bus. The result is that no service congestion occurs since local service invocations have the cost of local calls","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114247851","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}
