EJB (Enterprise JavaBeans) 3.0 is a commonly used database persistence technology in Java EE applications. EJB 3.0 has simplified the development of EJBs with an annotations-based API that eliminates the use of remote/local interfaces, home/local home interfaces, and deployment descriptors. A number of other books are available on EJB 3.0, but none covers EJB 3.0 support in Oracle Fusion Middleware 11g, which is one of the leaders in the application server market.This is the first book that covers all aspects of EJB 3.0 database persistence development using Oracle Fusion Middleware technology. It covers all the best practices for database persistence ensuring that your applications are easily maintainable. Leaving theory behind, this book uses real-world examples to guide you in building your own EJB 3.0 applications that are well integrated with commonly used Java EE frameworks.The book gets going by discussing the new features in the EJB 3.0 specification. As some readers may still be using EJB 2.0, the book explains how to convert your EJB 2.0 entity beans to EJB 3.0. It then goes on to discuss using EJB 3.0 database persistence with JDeveloper, WebLogic Server, and Enterprise Pack for Eclipse, the main Java EE components of Oracle Fusion Middleware 11g. The book also covers EJB 3.0 relationships and integrating EJB 3.0 relationships with JSF user interfaces. EJB 3.0 database persistence with some of the commonly used frameworks such as ADF Faces, AJAX, and Web Services is also discussed in the book. It uses the integrated WebLogic Server 11g in some of the chapters and the standalone WebLogic Server in other chapters. While JDeveloper is the primary Java IDE used in the book, one of the chapters is based on the Oracle Enterprise Pack for Eclipse.By the time you reach the end of this book, you will be well-versed with developing EJB 3.0 applications using the different Java EE components of Oracle Fusion Middleware 11g.
E-konsument w Europie - komparatywna analiza zachowań
Magdalena Jaciow, Agata Stolecka - Makowska, Robert...
Kraje Europy rozwijają się w różnym tempie, stopniu i zakresie, w zależności od czynników ekonomicznych, demograficznych, społecznych, kulturowych czy stopnia zaawansowania technologicznego. Innowacyjność gospodarki ma coraz większe znaczenie dla rozwoju danego państwa, ponieważ przekłada się na konkurencyjność podmiotów rynkowych i zwyczaje konsumentów. Jednym z przejawów tej innowacyjności jest wirtualizacja życia społeczno-gospodarczego, o określonych skutkach dla handlu międzynarodowego. Książka uzupełnia wiedzę w zakresie zachowań e-konsumentów w Europie. Autorzy skupiają się przede wszystkim na identyfikacji i porównaniu zachowań nabywczych e-klientów w wybranych krajach (we Francji i Włoszech, w Polsce, Portugalii, Rumunii i na Słowacji). Zawarto w niej także informacje, które mogą pomóc w podejmowaniu decyzji przedsiębiorstwom prowadzącym działalność w Internecie i kierującym ofertę do e-konsumentów na obszarze naszego kontynentu. Książka stanowi swoiste kompendium wiedzy na temat zachowań e-konsumentów w Europie, pozwala zidentyfikować ich profil demograficzno-psychograficzny oraz wskazać, jak zachowują się dokonując zakupów w Internecie. To powoduje, że jest ona rzetelnym źródłem wiedzy w zakresie zachowań nabywczych młodych e-konsumentów a przez to może stanowić inspirację dla pracowników naukowych czy studentów prowadzących badania o takiej lub zbliżonej tematyce. prof. US dr hab. EDYTA RUDAWSKA, Uniwersytet Szczeciński (fragment recenzji książki) Analizy dokonane przez autorów pozwalają czytelnikowi zaktualizować swoją wiedzę na temat nowych wyzwań i możliwości, jakie stwarzają globalizacja i technologie internetowe. Styl pisania i struktura książki - mimo iż mamy do czynienia z pracą naukową - są przyjazne czytelnikowi. Książkę czyta się przyjemnie. Jest ona zarówno podręcznikiem, jak i „przewodnikiem” po zagadnieniach marketingu międzynarodowego i międzynarodowych badań rynku. Gorąco polecam. doc. Ing.
