(Switch) 13 core technologies of J2EE and j2ee13 core technologies I. JDBC (Java Database Connectivity) JDBC APIs provide a unified way to access different databases. Like ODBC, JDBC shields developers from some details. In addition, JDBC access to databases is also platform-independent. Ii. JNDI (Java Name and Directory Interface) The jndi api is used to run the name and directory services. It provides a c

With the rapid development of the Internet, communication technology is experiencing a huge revolution, because the number of users accessing the network rapidly increases. As a network connected to the end users in the communication network, the access network has become a hot topic in network technology. Currently, the main access technologies include hybrid fiber/coaxial (HFCs) access technology, optical fiber access technology, copper wire access

C ++ basics, important technologies, and basic technologies1. Implementation of class and object 1.1 The first method is to define the member functions of the class in the class body.The second method is to place the implementation of the member functions in the class body. In this case, the domain operator ":" is required, which has the same effect as the first one. Class apple {public: // data member int index; // member function int getindex () ;};

Java EE was originally in the browser and the client machine. At the time, many people questioned whether it was suitable for server-side development. Now, with the increase in Third-party support for the JAVA2 platform Enterprise version, Java is widely accepted as one of the preferred platforms for developing enterprise server-side solutions. The Java EE platform is comprised of a suite of service (services), application interfaces (APIs), and protocols that provide functional support for d

technologies of MySQL are familiar, such as the transaction mechanism (Isolation level , locks, etc.), to trigger, partition and other technologies have a certain understanding and application; For MySQL performance, there are disk optimizations (SAS migration to SSD), Server optimizations (memory, server itself configuration), and other core performance tuning options in addition to the two phase (Innodb_

conventions. JavaBean can provide common functionality and can be reused, which allows developers to extract some key functions and core algorithms to encapsulate as a component object, which increases the reuse rate of code and the security of the system. Advanced Web projects are applied to all of these technologies, and joint use and collaborative development between them can improve the efficiency of development and the performance of the system.

This chapter provides a general overview of WebService technologies and client-side invocation techniques. The figure above contains almost all the relevant content of the current webservice. I'm going to go through two big chunks to illustrate, that's the service side, the client. The service side mainly introduces the following 3 kinds: 1. Axis1 or Axis2 release WebService. 2. Use Xfire to publish WebService. 3. Use the latest CXF to publish WebSe

Of the Very best Ajax Tutorials Ajax is not a new language, it is actually a combination of several technologies (such as DHTML, Javascript, XML, and JSON) to become a powerful new technology. Ajax breaks the habit of page overloading, and with Ajax, users can create a direct, highly available, richer, more dynamic Web user interface that is close to local desktop applications. The following is an example tutorial for the 10 most common Ajax

users can get more resources nearby, so to speak, CDN = mirror (mirror) + cache (cache) + Load balancer (GSLB). At present, the CDN is based on the static data in the cache website, the user downloads the dynamic content from the main station server and then downloads the static file to the CDN.First, the CDN architecture:CDN implementation to consider load balancing, and load balancing includes DNS resolution load balancing, cluster load balancing and operating system load balancing, content m

The most important part of the Spring framework is the IOC (inversion of Control) container, which derives from the AOP (aspect-oriented programming) technology, the 80/20 rule, which solves most programming problems?! Finally, this is based on the test-driven development of TDD (test-driven-development).So, learning Spring is mainly engaged in three aspects, the most basic of the IOC, above the AOP, the last TestSpring Learning Note Core Technologies
