WEB容器:给处于其中的应用程序组件(JSP,SERVLET)提供一个环境,使JSP,SERVLET直接与容器中的环境变量接口交互,不必关注其它系统问题。主要由WEB服务器来实现。例如:TOMCAT,WEBLOGIC,WEBSPHERE等。该容器提供的接口严格遵守J2EE规范中的WEB APPLICATION 标准。我们把遵守以上标准的WEB服务器就叫做J2EE中的WEB容器。 容器:Ent...
web site includes online versions of the J2EE 1.3 BluePrints book, early access chapters to the upcoming J2EE 1.4 BluePrints book, a design pattern catalog put together by the authors of Core J2EE Patterns, and links to downloads of Pet Store and the adventure builder reference application. The...
Aggregating atomic pieces of the display together to create a single view introduces the potential for display errors, since subviews are page fragments. This is a limitation that can become a manageability issue. For example, if a JSP page page is generating an HTML page using a main page ...
If the user crosses the security policy domain boundary (for example, by requesting a Web application that is deployed in a different domain), he or she is forced to re-authenticate.In the context of Web applications and single sign-on on the J2EE Engine, a security policy domain must be...
WAF是WEB APPLICATION FRAMWORK的简称,是SUN蓝皮书例子程序中提出的应用框架。它实现了 MVC和其他良好的设计模式。 2.4.1. 细节分析 2.4.2. 视图-控制-模型 如图所示,开发人员编写的两个xml配置文件定义了WAF的运作参数。Screendefinition.xml定义了一系列的屏幕(screen)。Mapping.xml则定义了某个动作之后应该显示的屏...
Writeapplication.xmlyourself (more info). To use theDDInittools, just open a command window, move one directory level above the deployment directory (in our example, that'sbanking\deploy, aboveejbandweb). Then, enter either of these commands: ...
JNDI的高级使用支持对java对象和其他信息的复杂的存储和检索。 2什么是命名和目录服务 命名服务提供了一种为对象命名的机制,这样我们就可以不需要知道对象的具体位置而可以很方便的获取和使用对象,这类似于我们的web访问,我们可以定位到任何网络能够访问到的机器上的对象。
A J2EE module is a collection of one or more J2EE components of the same container type (for example, web or EJB) with deployment descriptors of that type. One descriptor is J2EE standard, the other is Sun Java System Application Server specific. Types of J2EE modules are as follows: ...
WebSphere Application Server 通过使用缓存实例存储和管理缓存的 Java 对象。缓存实例还可以用于对相关的对象进行逻辑分组。特定实例的缓存中存储的对象不会受到其他缓存实例的影响。如上所述,DistributedMap 公共接口使得应用程序可以直接访问缓存实例。 应用程序可以存储和检索任何实现了 java.util.Map 接口的对象。您所...
In the code example that can be downloaded in this article, you can find a table integrated in the server-side processing mode.For more details about integrating DataTables with a Java web application, see the JQuery Data Tables in Java Web Applications article....
