These days, looking at some Java things, because just start, not very understanding of Java, the results of some Java nouns do not have a clear context, and now a little to tidy upI am struggling with Jdk,sdk,jre,jvm,ide,adt, cross-platform, j2ee,j2se, these nouns make me foggy.First, what is the SDK?Software Develop Kit, as the name implies, is the software development package. Software developers implement the underlying modules and encapsulate them

I. J2EE Concept Currently, the Java 2 platform has three versions. These are the micro version of Java 2 platform (Java 2 platform Micro Edition, j2_based) applicable to small devices and smart cards) java 2 platform Standard Edition (Java 2 platform Standard Edition, j2se) for desktop systems and Java 2 Platform Enterprise Edition (J2EE) for creating server applications and services ).

j2ee| Solution | problem | Chinese Java Chinese problem has been plagued by many beginners, if you understand the Java system in Chinese problem principle, we can take a fundamental solution to the Chinese problem. The oldest solution is to use string bytecode conversion, which is inconvenient, and we need to break the encapsulation of the object and do bytecode conversion. There is another way to the Java-EE container coding settings, if the applicat

Keeping track ofthe software impact ect, the competing "standards" can be bewildering. yet wocould you believe that today's choices actually make it a relatively easier time for enterprise developers, compared to the previous generations of tools? Microsoft and sun share compelling visions for a new enterprise architecture, and each vision features strong interoperability through Web Services and varous standards. it's certainly easier to deal with. net Framework and the Java 2 Platform Enterpri

Always use the MVC framework. 2. apply automatic unit testing and test management at each layer. 3. develop according to the specifications, rather than the application server. 4. Plan to use J2EE Security from the very beginning. 5. create what

I. Introduction Nowadays, more and more enterprise applications are built on the J2EE platform, thanks to the good framework and service support provided by J2EE for enterprise application development. j2EE provides enterprise applications with various services (such as security, transaction, and naming ). this document describes the security services provided by

Absrtact: Text will describe the author's experience in ANDROID+J2EE system integration development, hoping to inspire. A long time ago, I heard people say that Android will fire up later, as a forward-looking, understanding of it will be a good opportunity for transformation. Javaweb is too mature saturation, now on the market, a variety of Android phones, online, like a variety of Android video serials follow, Android has become a hot topic, just at

ajax|j2ee| Online Conference This year everyone in the hype Web2.0, one of the technology Ajax is also followed by fire, so I wrote a paper called "Cheat Ajax" article, simply analyze the essence of AJAX technology. Although I do not like to follow the follow, but there are some areas of Ajax is more useful. Some time ago did a EASYJF open source team of online conferencing system, used AJAX technology, the following design ideas

Since is the actual combat, first we create for oneself a development user, and creates a table!!There are more ways to create new users and tables in Oracle, as long as

Liu Yi (jeru@163.net)Bachelor of information and computing science, Wuhan University This article provides a comprehensive introduction to J2EE in five aspects. Starting from the concept of J2EE, to its advantages, to the typical J2EE layer-4 model, and its framework structure, it is finally an introduction to the thirteen core technologies of

With the rapid development of Internet networks, Internet-based enterprise applications require that software platforms be open, distributed, and platform independent. As a result, technologies such as rpc/COM/CORBA have emerged one after another, but these technologies have many shortcomings and limitations in practical application. Their specific protocols are difficult to pass through the firewall, so they are not suitable for application development on the web. To further develop web-based a

At present, there are more and more J2EE learners. With the continuous development of J2EE technology, various new concepts have emerged. I hereby write this article, the purpose is to explain these concepts to beginners from an easy-to-understand perspective, so that everyone can learn the J2EE learning direction and achieve a clear understanding. First, we need

J2EE is a complete set of standardized integration platforms for developing enterprise applications of mission-critical. Its many specifications and wide content bring a lot of "trouble" to the Development of J2EE applications ". For example, to implement Content-based RDBMS storage, we may use JDBC, Entity Beans, JDO, O/R Mapping tools (TopLink, Hibernate), XML-DBMS, JAXB, and other methods (some of which

The storage location of the first node in the list is called the head pointer, so the entire list must be accessed from the beginning. Each subsequent node, in fact, is the position that the previous successor pointer points to. Here is a place to pay attention to, is the concept of the right pointer, this is very important. The storage location of the first node in the list is called the head pointer, and
