Morgan and Yeung set out a diverse andstimulating selection of materials and give them context with a compre-hensive and critical commentary. By adopting an interdisciplinary approachand emphasising the role of law in its broader social and political context, itwill be an invaluable tool for the student coming to regulation for the firsttime. This clearly structured, academically rigorous title, with a contextualizedperspective is essential reading for all students of the subject.BRONWENMORGANis Professor of Socio-legal Studies at the University ofBristol.

She was auniversity lecturer at Oxford University and a Tutorial Fellow in Law atSt Anne’s College from 1996 until 2006. Her research lies in the intersectionof public law and socio-economic regulation. The Law in Context SeriesEditors: William Twining (University College London) and Christopher McCrudden(Lincoln College, Oxford)Since 1970 the Law in Context series has been in the forefront of the movement tobroaden the study of law. It has been a vehicle for the publication of innovative scholarlybooks that treat law and legal phenomena critically in their social, political and eco-nomic contexts from a variety of perspectives. The series particularly aims to publishscholarly legal writing that brings fresh perspectives to bear on new and existing areas oflaw taught in universities. A contextual approach involves treating legal subjects broadly,using materials from other social sciences, and from any other discipline that helpsto explain the operation in practice of the subject under discussion. It is hoped thatthis orientation is at once more stimulating and more realistic than the bare expositionof legal rules. The series includes original books that have a different emphasis fromtraditional legal textbooks, while maintaining the same high standards of scholarship.They are written primarily for undergraduate and graduate students of law and of otherdisciplines, but most also appeal to wider readership. In the past, most books in theseries have focused on English law, but recent publications include books on Europe law,globalisation, transnational legal processes and comparative law.Books in the SeriesAnderson, Schum & Twining: Analysis of EvidenceAshworth: Sentencing and Criminal JusticeBarton & Douglas: Law and ParenthoodBeecher-Monas: Evaluating Scientific Evidence: An InterdisciplinaryFramework for Intellectual Due ProcessBell: French Legal CulturesBercusson: European Labour LawBirkinshaw: European Public lawBirkinshaw: Freedom of Information: The Law, the Practice and the IdealCane: Atiyah’s Accidents, Compensation and the LawClarke & Kohler: Property Law: Commentary and MaterialsCollins: The Law of ContractDavies: Perspectives on Labour LawDembour: Who Believes in Human Rights?: The European Convention in Questionde Sousa Santos: Toward a New Legal Common SenseDiduck: Law’s FamiliesElworthy & Holder: Environmental Protection: Text and MaterialsFortin: Children’s Rights and the Developing LawGlover-Thomas: Reconstructing Mental Health Law and PolicyGobert & Punch: Rethinking Corporate CrimeHarlow & Rawlings: Law and Question Bank Introduction to .NET and Programming in C# 1. .NET is said to accelerate the next generation of the Internet [0.5] a) True b) False 2.

We cover version 1.0 of the Java portlet API, also known as Java Specification Request (JSR) 168. Portlets are the individual components that pro- vide content for a portal. Portals aggregate one or more portlets into web pages, which are usually personalized or customized for individual users or groups of users. Some portals also support mobile devices and voice support. Before the release of this portlet API, each portal had a different API for develop- ing portlets. Most Java portal vendors will support the JSR 168 standard in addition to their existing proprietary API. If you develop your portlets to the new portlet API standard, you can deploy them on any JSR 168-compatible server, just as any com- patible servlet container can deploy servlets. You may use the open source portal server Apache Pluto to run the portlets we write in this book. You are able to deploy your portlets on any other portals that support the standard, because none of the portlets will use any proprietary features. We use several open source software components to provide additional functionality beyond the portlet API. Some of the problems we provide solutions for in later chapters are person- alization, portal deployment, Single Sign-On (SSO), content syndication, and the porting of an existing application into a portal infrastructure. In this chapter, we discuss portals, information architecture, and background on the portlet API. Providing a Solution with Portals Usually, the decision to build a portal environment is made at a high level within an organization after users become frustrated with using applications that are not integrated and are not immediately visible. Other times, a project involving an extranet for suppliers and customers gets started, and the easiest way to aggregate security for all of these new users is through a portal’s SSO feature. In this book, we do not discuss the business case for a portal within an organization. We wrote this book for developers and architects who have chosen to use a portal server that implements the Java portlet API and need to solve technical problems. 2840ch01.qxd 7/13/04 12:43 PM Page 1 Download at Boykma.Com Chapter 1 2 From a technical perspective, a portal provides a solution for aggregating con- tent and applications from various systems for presentation to the end user. The users do not need to know how the content or functionality is provided; they just want to enjoy the benefits of a single web site and all of its services. Typically, a portal has an integrated user interface and an SSO approach for security. The software developer’s job is to take all of the systems that provide these services and add interfaces to them to work with the portal. Portlets are the individual compo- nents displayed in the portal. Prior to the introduction of the standardized portlet API, portlets had to be custom-developed for each portal server because the API was different for each server. The leading portal vendors joined to create a standard to promote portal technology. Inside the Java Community Process (JCP), the name of the standard for the first version of the Java portlet API is JSR 168. Future versions of the portlet API will have different JSR numbers. One of the problems for the designer or architect in charge of the portal proj- ect is that the existing systems do not always separate cleanly into presentation and business logic layers. Also, consider portal security and personalization when .. .Introduction to Society and Social Interaction be no tricks or cheating, simply warrior against warrior If all goes... remembered and acknowledged throughout the community, even among other tribes To the Maasai, lion hunting is about more than food and security It is a way to strengthen the bonds of community and the... village members come to congratulate the victors The warrior who wounded the lion first is honored and given a nickname based on his accomplishment Songs are sung about the warrior, and from now on
