and a lifesaver for the ever-expanding Java EE system based on component-based, covered technology. It inserts a control component between the browser (the client agent is called the browser) and the JSP or servlet. This control component concentrates on handling the distribution logic of HTTP requests sent by the browser, that is, it distributes the request to the corresponding

1 Preface In the field of enterprise-class application system development, the Java EE architecture is now universally accepted. Although it has not fully honoured the new appearance of all kinds of beautiful promises, cross-platform, distributed, easy to develop and maintain, but the popularity of Java

result can be obtained by repeating the same parameter call. These methods do not affect the state of the system and can be called repeatedly without worrying about changing the system. For example: GetUserName () is idempotent, and DeleteFile is not. It is an important concept when we discuss HTTP session invalidation and EJB failover. java cluster What types of objects can be clustered? -only those components that can be deployed to the distribute

Generally speaking, the formation of the current Java-EE enterprise development efficiency is low because of a few: the division of meticulous, technical line long, customers can not participate in the development of the complexity of too high. These aspects of the factors between cause and effect, interaction, and finally the entire development process dragged into the mire. The following is discussed in d

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
