J2ee| Project In my experience as a developer, senior developer, architect, I have encountered good, poor, and even ugly enterprise-class Java projects. When I ask myself what makes a project successful and another failure, I find it hard to get a perfect answer, as if it's hard to define all the software projects with success. The Java EE project is no exception. Therefore, the project is divided into different levels of success or failure. In this a
Java EE is divided into: Lightweight Java EE Spring, hibernate as the core, without application server support, as long as it works well on a Web server such as Tomcat, jetty, etc. Classic Java EE With EJB3 as the core, need EJB container support , need to run in JBoss, WebLogic, WebSphere application Server ;The front-end MVC frame
The Java EE platform is comprised of a suite of services (service), application interfaces (APIs), and protocols that provide functional support for developing enterprise applications. 13 Core technologies are JDBC, JNDI, EJB, RMI, JSP, SERVLET, XML, JMS, Javaidl/corba, JTS, JTA, JavaMail and JAF.What is enterprise-class application?1. The amount of data is particularly large.2. The user is very much.3. High performance requirements.4. High security r

Section 1:application Design Concepts and principles Explain the main advantages of a object-oriented approach to system design including the effect of encapsulation, inherit Ance, and use of the 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 Edition application. Tiers include client (both GUI and web), Web (Web Container), Business (EJB container), integra

In recent years, the development of the Java industry has grown exponentially. As an enterprise application developer, architecture architect, or technical manager, you can choose from many vendors, best practices, specifications, and component types for your Java technology implementation. The purpose of the Java EE Explorer series is to help you find a way to assist you in selecting the right technology for any given situation. In this article, the
Currently, there are 3 versions of the Java 2 platform, which are Java 2 platform Micro (Java 2 Platform Micro edition,j2me) for small devices and smart cards, Java 2 Platform Standard Edition for desktop systems (Java 2 Platform Standard edition,j2se), Java 2 Platform Enterprise Edition for creating server applications and Services (Java 2 Platform Enterprise edition,j2ee). Java EE is an architecture that leverages the java-based 2 platform to simpli
This problem occurs when you add a project to Tomcat today: Tomcat version 6.0 only supports EE 1.2, 1.3, 1.4, and Java EE 5 Web ModulesThe reason for this is that the project used to be TOMCAT7. X now changes to tomcat6.x. (It should be possible to upgrade Tomcat to 7.x, but there is a tomcat6.x for the project now.) So I keep tomcat6.x)The workaround is to modify version= "3.0" in Org.eclipse.wst.common.p
WTP is very convenient to use the Eclipse IDE for Java EE developers, but it is too large and I like to configure on demand. First, let's understand what WTP is. The WTP (Web tools Platform) project expands on the Eclipse platform and is a toolset for developing Java EE WEB applications. WTP contains the following tools: A source editor can be used to edit HTML, Javascript, CSS, JSP, SQL, XML, DTD, X

Java EE Cluster Generally speaking, Java EE cluster technology includes "load Balancing" and "failover" two parts. In the above illustration, load balancing means that a target object is requested by many client objects simultaneously. The load balancer is between the caller and the callee, and you can distribute the request to a target object with the same functionality but different locations. Both hig
