Client interaction can be presented through plain HTML web pages, through web pages powered by applets, Java Servlets, or JavaServer Pages technology, or through stand-alone Java applications. Another advantage of the J2EE platform is that the application model encapsulates the layers of functionality in specific types of components. Components communicate transparently using various standards: HTML, XML, HTTP, SSL, RMI, IIOP, and others. Entity beans are intended to be persistent, surviving as long as the data they're associated with remains viable. Mozilla Corporation Firefox. Containers intercede between clients and components, providing services transparently to both, including transaction support and resource pooling. De Java / J2EE Developer voor deze relatie is een ‘technologist’ met een sterke focus voor de business, opererend in commerciële en overheidsomgevingen. Wilt u Java downloaden voor een andere computer of een ander besturingssysteem, klik dan op de onderstaande koppeling. Connectors promote flexibility by enabling a variety of implementations of specific services. The JSP 2.0 specification supports static templates, simplified access to Java objects, and easy extensibility.Enterprise JavaBeans (EJB) technology enables a simplified approach to multitier application development, concealing application complexity and enabling the component developer to focus on business logic. And, because it's based on the Java programming language, this model enables all J2EE applications to achieve all the benefits of Java technology: scalability, portability, and programming ease. Thanks to the J2EE application model, maybe the most interesting thing about J2EE applications is what they don't do. Connectors sit beneath the J2EE platform, defining a portable service API that communicates with existing enterprise vendor offerings. Support for simple HTML means quicker prototypes, and support for a broader range of clients.
Java-technologie biedt een veilige computeromgeving voor werk en ontspanning. The functionality of J2EE is developing and deploying multi-tier web-based enterprise applications. The bottom line benefits are increased programmer productivity, better strategic use of computing resources, and greater return on an organization's technology investments.The J2EE application model divides enterprise applications into three fundamental parts: components, containers, and connectors. Session beans can serve as Web service endpoints. Technisch ontwerp en implementatie; Java Servlets enable developers to easily implement server-side behaviors that take full advantage of the power of the rich Java API. Java Platform, Enterprise Edition（Java EE）はコミュニティ主導のエンタープライズ・ソフトウェアの標準です。 Java EEは Java Community Process を使って開発されており、業界の専門家、営利団体とオープンソース団体、Javaユーザー・グループ、さらに数え切れないほど多くの個人が貢献しています。 Entity beans represent collections of data -- such as rows in a relational database -- and encapsulate operations on the data they represent. J2EE Interview Questions. Belangrijke update van de Oracle Java licentie De Oracle Java licentie is gewijzigd voor releases vanaf 16 april 2019. This means that an e-commerce site could be built using a combination of off-the-shelf EJB components for shopping cart behaviors, modified EJB components for specialized customer services, and completely customized layouts using JavaServer Pages technology that bring a unique look and feel to the site. For server-side generation of dynamic content, the J2EE platform supports two types of web component technologies: Java Servlets and JavaServer Pages (JSP). Business logic is encapsulated in Enterprise JavaBeans (EJB) components. The messages may be sent by any J2EE component--an application client, another enterprise bean, or a Web component--or by a JMS application or system that does not use J2EE technology.The Java 2 Platform, Enterprise Edition version 1.4 is the most complete Web services platform ever. Java EEの概要 Java Platform, Enterprise Edition（Java EE）はコミュニティ主導のエンタープライズ・ソフトウェアの標準です。Java EEはJava Community Processを使って開発されており、業界の専門家、営利団体とオープンソース団体、Javaユーザー・グループ、さらに数え切れないほど多くの個人が貢献しています。
Session beans represent behaviors associated with client sessions -- for example, a user purchase transaction on an e-commerce site.
A message-driven bean normally acts as a JMS message listener, which is similar to an event listener except that it receives JMS messages instead of events. Clients can run on desktops, laptops, PDAs, cell phones, and other devices.

Containers and Connectors: Hiding Complexity, Enhancing Portability JavaServer Pages technology combines the ubiquity of HTML with the power of server-side dynamic content generation. Note that "J2EE" usually references Java EE 1.2 up to 1.4. Additionally, the J2EE platform supports automatic download of the Java Plug-in to add applet support where it's lacking. In particular, connectors implementing pluggable messaging contracts enable bidirectional communication between J2EE components and enterprise systems.The J2EE platform provides choices for graphical user interfaces across a company's intranet or on the World Wide Web. De nieuwe Oracle Technology Network licientieovereenkomst voor Oracle Java SE verschilt aanzienlijk van eerdere Oracle Java licenties.
