are not reserved.Of course, there are many similar frameworks. As a team developing J2EE applications, we need to filter various frameworks and select a Framework suitable for the project requirements, teams, and company development directions.Generally, too many frameworks are not suitable for the target products to be developed. First, various J2EE technologies have developed rapidly, and too many framew

As mentioned above, different vendors provide their own J2EE solutions, such as IBM WebSphere and BEA WebLogic. All the examples in this book are run in a reference implemention) the reference implementation is provided by Sun free of charge, which fully complies with J2EE specifications. It should be noted that this reference implementation is just a working model and is not suitable for enterprise-level d

after JDK, tomcat, and eclipse are installed, and tomcat-plugin and lomboz-plugin required for JSP development are installed, the J2EE development environment has been set up. However, in case of computer poisoning, the system needs to be reinstalled once and for all, this complicated process has to be re-launched. Therefore, it is best to install these systems in the same root directory from the very beginning, for example, E: \

. Although the J2EE platform has improved the standard of living for ordinary enterprise developers, this improvement is at the cost of having to learn many specifications and technologies, these specifications and technologies are integrated by J2EE to become an all-encompassing distributed computing platform.

In my experience as a developer, Senior developer, or architect, I have encountered good, bad, or even ugly enterprise-level Java projects. When I ask myself what makes a project succeed and another failure, I find it difficult to get a perfect answer, as if it is difficult to define all software projects with success. The J2EE project is no exception. Therefore, projects are divided into different levels of success or failure. In this article, I main

specifications. JDBC Specification was the first standard to be downloaded. Many concepts are clear at a glance, especially the transactional control of the DATABASE. I have gained a deeper understanding of her understanding. For the development of C/S structures, such as Swing + JDBC, the development of database application systems, let me learn to develop two-layer structure application systems. Awesome. I don't know when to start developing a webs

install j2sesdk before installation.After installation, you must set the java_home, j2ee_home, and classpath environment variables and run j2eeserver.To facilitate developers, Sun divides Java into j2se (java2standardedition), java2javasiseedition, java2microedition, and javacard. J2se is the foundation of all Java technologies. No matter what platform Java applications developers need to develop, they must first learn from j2se. The

J2EE development framework (6) and j2ee development framework There are many orm frameworks, such as guzz, hibernate, and mybaits ...., when encapsulating a framework, we can choose one or more implementations for future use. Here I only implement hibernate, And the directory structure is as follows: 1. first, query the BaseRepository interface. This interface is generic: T indicates the object type, and I

the following section, we will describe various technologies that constitute J2EE and learn how WebLogic servers support them in a distributed application. The most common J2EE technologies are JDBC, JNDI, EJB, JSP, and servlets. We will take a closer look at these technologies. Java database connectivity (JDBC) The jdbc api accesses a variety of databases in a

The J2EE project needs to run through the Deployment Server. What are common deployment servers? In java, tomcat or wbelogic is generally used (less)This i

. Even more commendable, Rod Johnson does not try to claim that his solution is a perfect method for Java Enterprise applications. Throughout the book, readers can feel that Johnson most wishes to convey to readers a "evidence-based architecture" method based on practice. If this book has its unique merits, I think it is not because it promotes IOC or AOP, but because it helps some readers break through the technical knowledge, learn to select an arc

of common programming tasks on your behalf, including providing transaction services, security fields, reliable messages, name and directory services, database access and connection pools, thread pools, load balancing, and fault tolerance Processing. By providing these public services in a standard and easy-to-use way, products such as WebLogic servers have created application systems with better scalability and maintainability, this increases availability for a large number of users.

Digress: It was just half a year ago when I got started with java. When I first learned java well, I forgot cpp. Now I have put the hot cpp in my hand and picked it up again, can I remember these two OOP languages clearly? All of the following are from Teacher Liu Yan of Tongji University (EnterpriseJavaProgramming) 1. What is Servlet? When I learned J2EE for almost a month, I suddenly began to ask myself, but what is the role of Servlet in MVC Patter

P.s: From the PHP project team to the Java project team, I am a beginner of J2EE. I found this article and reposted it. I hope you can spur me. Java has developed into three main parts by application: j2se, j2-and J2EE. These three modules complement each other and have different application scopes. J2se is the standard version of Java2 and is mainly used for programming desktop applications; Mainly used f
