Using SOAP as a UDDI Search Engine by Bilal Siddiqui
In this paper we will take a detailed look at the Description, Discovery and Integration process. For this purpose, we will discuss UDDI's usage models and its internal architecture. We will then see what's already present on existing UDDI registries and conduct a detailed analysis of SOAPClient.com, one of the leading UDDI related services of today. We will then move on with an in-depth discussion of what else UDDI offers as a search service and show that in fact it offers a lot that is yet to be brought to common Internet users. We present a conversation between an Internet user and a UDDI registry. The user specifies what service they want, and the registry responds. While doing this, we will design a Graphical User Interface (GUI), which will implement the User-UDDI conversation. We round off with a look at a smaller version of the GUI, for use on J2ME enabled devices, and a discussion of the technological and architectural issues involved in such a design process.

J2EE based Web Services Solution for Health Insurance Portability and Accountability Act Compliance by Kapil Apshankar
The Health Insurance Portability and Accountability Act (HIPAA, The Act) is poised to become the next Year 2000 or Euro issue in terms of deadlines and revenue expenditures. What sets The Act apart from Y2K, however, is the geographical impact region - only the USA in this case. Just as solution providers are rising up after the economic downturn, this is a golden opportunity to both bring in new business and introduce new technologies into an otherwise legacy applications sector. After covering the background in a little more detail, this paper looks more closely at a J2EE-based Web Service methodology which can be used to provide industry standard solutions. Also included are the advantages and disadvantages of a J2EE solution as compared to a .NET solution using Web Services.

Web Services and Remote References by Jørgen Thelin
What are "remote references", and how do they relate to distributed object technology? Are the concepts of a remote object reference still applicable for Web Services technology? This paper describes the software architecture concept of remote references and shows why they are best avoided when using XML Web Services due to the fundamental mismatch between the service oriented middleware approach of Web Services and the object oriented middleware required to support a remote reference architecture. It assesses the impact of remote references on interoperability between different Web Service infrastructure products and applications, and examines some ways architects and developers can minimize the problems in this area. It also examines the problem of exposing as a Web Service an existing system that already uses remote references extensively as remote factory objects (which is a very common approach in mature CORBA systems), and how a simple "façade application" can be used in this context.

Web Services and the Real Estate Industry by Kunal Mittal
This paper focuses on how Web Services can revolutionize the real estate industry. We concentrate on the residential real estate industry, identifying the complex nature of a real estate transaction. It emphasizes the fact that the number of distinct people involved in a single transaction, and the coordination and management of these people to serve the best interests of the buyer and seller, is an intricate process. We present ideas on how Web Services can be used to streamline these interactions. The concepts described in this paper can be similarly applied to the commercial real estate industry.

Network Security for Web Services by Whitney Hankison
These days, building a secure network infrastructure involves much research and implementation planning. The fundamental strategy of building a secure environment involves letting subscribers access authorized resources without hindrances while ensuring that intruders fail to gain access. In this paper we outline what the concerns are, some steps to remediation, and some further sources of information. In addition we approach security from a programmatic standpoint and discuss measures developers need to take to add to the security of a Web Services application.

Web Services and Logistics by John Fou
In this paper, we take a look at the application of Web Services in the area of logistics. Our case study offers an insight into a slightly unusual aspect of logistics, in that it doesn't pertain to the shipping of large quantities of goods. The information upon which our discussion is based comes from interviews carried out with Wade William from Networkcar, and examines the use of Web Services in their real time processing of diagnostic data from vehicles. As well as more details on the Web Services exposed, and more information on the business benefits, we take a look at the differences between the architectures of the old and new systems.

Web Services Security by Eduardo B. Fernandez
At the InfoWorld Next Gen Web Services conference in January 2002, 51% of the attendants considered security the single largest obstacle to general acceptance of Web Services. Are these fears warranted, or are these people just scared of something they don't fully understand? Is the security of Web Services so precarious? Can we overcome these problems so that businesses and the general public will trust these services? In the extended version of this article, we take a more in depth look at these issues, along with examining who is doing what to provide security for our Web Services.

UDDI Based Electronic Marketplaces by Bilal Siddiqui
eMarketplaces are designed to bring together businesses on the Web. Both buyers and sellers should be able to interact with each other inside an architecture that is easy to use and maintain. eMarketplace owners can implement several types of processes depending upon their target audience, operations and finance models. The greatest benefits lie with cost reduction for all players and the ability to reach otherwise untapped business prospects. This paper discusses how UDDI and WSDL work together to form the core architecture of the next generation e-commerce model, increasing efficiency and reducing the costs inherent in B2B integration.

Testing for SOAP Interoperability by Judith M. Myerson
The one big reason why many enterprises look to Web Services for increased operational efficiency is the promise of cross-platform, cross-language interoperability, and increased operational scope, especially for the small and medium-sized enterprises. This promise, in reality, has not been completely fulfilled to date, as we still encounter interoperability problems, particularly with Simple Object Access Protocol (SOAP) and Web Services Description Language (WSDL). In this paper we look at SOAP and WSDL, in both cases version 1.1, and in more detail at the interoperability testing available.
