Entity Bean: Provides robust data persistence. The bean container handles most of the data integrity, resource management, and concurrency features, allowing developers to focus on business logic and data processing, rather than these low-level details. When using bean-managed persistence (Bean Managed persistence,bmp) entity beans, developers write persistent code and the container determines when the code
Section 1:application Design Concepts and principles Document a given system architecture by creating UML diagrams for it Explain the main advantages of an object-oriented approach to system design. Including the effect of encapsulation, inheritance, and use of interfaces on architectural characteristics. Describe how the principle of "separation of concerns" have been applied to the main system tiers of a Java Platform, Enter Prise E
Kodo EJB is a framework that supports object/relationship mapping, and Kodo EJB, in addition to supporting the lightweight persistence layer framework in common Java applications, supports the need to meet heavyweight enterprise applications in Java EE containers, as required by the EJB3 specification, taking full advantage of

1. Layered model for Java EE applications1.1. The Java EE architecture pattern can be broadly divided into the following layers:>> domain object layer: This layer is composed of Pojo (Plain old Java object, common, traditional Java
1. DefinitionA container is an interface between a component and the underlying service details. Before a Web component, an enterprise bean, and so on can be executed, it must be assembled into a Java EE module and deployed on a container. Such as: The assembly process mainly includes: Custom container transaction management features, Jndi services, etc. Of course, in

Java EE 7 provides a complete, comprehensive, integrated stack to help you build enterprise and Web applications. Java EE container Mostly JSF (JavaServer Faces) and EJB (Enterprise Java Bean) Two parts, JSF relies on EJB, and is heavyweight, JSF uses a lot of component con
Overview: Most application performance management (APM) solutions only consider and analyze performance issues at one level of the Java application. This approach is not sufficient to address the performance problems of architecture-complex applications. A good APM tool should enable you to drill down from the Java EE layer into the database layer to ensure that
JSF 2.0 Despite the fierce competition of Java in the presentation layer framework, JSF still sticks to its own territory. Although there are many questions about JSF's ease-of-use and robustness, jsf2.0 is designed to solve these problems positively. Its ease-of-use, innovation, and scalable features include: JSF officially uses facelets as the view technology. Maybe you are not familiarFacelets is also an open-source view technology that integrate
Many successful enterprise applications are built using the Java EE platform. However, the principles of Java EE are not designed to effectively support WEB 2.0 applications. A deeper understanding of the disconnect between Java EE
Google App Engine, you don't need to use virtual machines or install and manage operating systems, software, and databases. So far you can only use Python to program on the above, and data extraction and storage through the Datastore (permanently effective service). You are responsible for developing and deploying your application. You also have Google accounts, such as Gmail. Without operating systems, servers, and databases, but now it is still limited to Python and datastore, which makes it
Java EE introduction Java EE basic architectureThe birth of Java EE is to solve the disadvantage of traditional C/s architecture: The client is bloated and poor in expansibility. Java

So that later people less detours.Java development to now, according to the application to divide into three major chunks: J2se,j2me and
Software 152 Tang WeiJava EE uses a multi-tiered distributed application model, where the application logic is divided into components based on functions, and each application component is distributed on different machines depending on the layer in which they reside.In fact, the original purpose of Sun design Java EE is to solve the problem of the two-tier model
