In most cases, portlets are built to be deployed by local portals. This is not practical if the organisation wishes to publish their Web services and expects other business partners to use these services in their portals. UDDI extension for WSRP enables the discovery and access to user facing Web services provided by business partners while eliminating the need to design local user facing portlets. Most importantly, the remote portlets can be updated by the Web service providers from their own servers. Remote portlet consumers are not required to make any changes in their portals to accommodate updated remote portlets. This results in easier team development, upgrades, administration, low cost development, and usage of shared resources. In this chapter, we deal with the technical underpinning of the UDDI extensions for WSRP (user facing remote Web services) and their role in service sharing among business partners. We outline the WSDL extensions relevant to the remote portlets and WSRP (WSRP specification version 1, 2003). publishing and binding process in UDDI.

In SOA framework, Portal applications aggregate and render information from multiple sources in easily consumable format to the end users. Web services seem to dominate the integration efforts in SOA. Traditional data-oriented web services require portlet applications to provide specific presentation logic and the communication interface for each web service. This approach is not well suited to dynamic SOA based integration of business processes and content. WSRP 2.0 aim at solving the problem and providing the framework for easy aggregation of presentation services. Is not practical to publish portlets locally if the organisation wishes to publish their portlets as web services to allow their business partners using these services in their portals. UDDI extension for WSRP enables the discovery and access to user facing web services while eliminating the need to design local user facing portlets.

Purpose The success of web services involved the adoption of this technology by different service providers through the web, which increased the number of web services, as a result making their discovery a tedious task. The UDDI standard has been proposed for web service publication and discovery. However, it lacks sufficient semantic description in the content of web services, which makes it difficult to find and compose suitable web services during the analysis, search, and matching processes. In addition, few works on semantic web services discovery take into account the user’s profile. The purpose of this paper is to optimize the web services discovery by reducing the search space and increasing the number of relevant services. Design/methodology/approach The authors propose a new approach for the semantic web services discovery based on the mobile agent, user profile and metadata catalog. In the approach, each user can be described by a profile which is represented in two dimensions: personal dimension and preferences dimension. The description of web service is based on two levels: metadata catalog and WSDL. Findings First, the semantic web services discovery reduces the number of relevant services through the application of matching algorithm “semantic match”. The result of this first matching restricts the search space at the level of UDDI registry, which allows the users to have good results for the “functional match”. Second, the use of mobile agents as a communication entity reduces the traffic on the network and the quantity of exchanged information. Finally, the integration of user profile in the service discovery process facilitates the expression of the user needs and makes intelligible the selected service. Originality/value To the best knowledge of the authors, this is the first attempt at implementing the mobile agent technology with the semantic web service technology.

In the modern electronic business world, services offered to business partners as well as to customers have become an important company asset. This again produces interests for attacking those services either to paralyze the availability or to gain unauthorized access. Though founding on decades of networking experience, Web Services are not more resistant to security attacks than other open network systems. Quite the opposite is true: Web Services are exposed to attacks well-known from common Internet protocols and additionally to new kinds of attacks targeting Web Services in particular. This chapter presents a survey of different types of such Web Service specific attacks. For each attack a description of the attack execution, the effect on the target and partly the results of practical experiments are given. Additionally, general countermeasures for fending Web Service attacks are shown.

This paper focuses on addressing the problem of web service monitoring by evaluating its suitability and privacy in a distributed web service environment (DWS). The need for web services monitoring and evaluation is necessary because the quantity and quality of retrieved web services generally does not fulfill the demands or requirements of the web service requesters. In the literature, many authors proposed suitable solutions for checking the quality of web service in an ad hoc scenario but there is no available testbed for this purpose. In this work, it is proposed to develop a framework as a testbed for evaluating the web service for its suitability and privacy. In order to verify, the retrieved web services fulfill the demands and requirements of the requester in a DWS environment. The Framework to Evaluate the Web Service Suitability (FEWSS) supports service providers in modeling the services with testbed and to design service behavior to comply the service suitability. It generates run-time instances of web services, client's requests, service registries and other entities in order to emulate realistic SOA environments. By generating a real testbed, our approach assists in runtime test for provider system/services. Particular focus has been put on the privacy policy extensibility to allow the service providers and users in a complex environment. FEWSS also provides an intuitive interface for testing all services under SOA control.

Recently, web services have presented a new and evolving model for constructing the distributed system. The meteoric growth of the Web over the last few years proves the efficacy of using simple protocols over the Internet as the basis for a large number of web services and applications. Web service is a modern technology of web, which can be defined as software applications with a programmatic interface based on Internet protocol. Web services became common in the applications of the web by the help of Universal, Description, Discovery and Integration; Web Service Description Language and Simple Object Access Protocol. The architecture of web services refers to a collection of conceptual components in which common sets of standard can be defined among interoperating components. Nevertheless, the existing Web service's architecture is not impervious to some challenges, such as security problems, and the quality of services. Against this backdrop, the present study will provide an overview of these issues. Therefore, it aims to propose web services architecture model to support distributed system in terms of application and issues.
