我们跟外面的差距真的太大了，这一趟下来文定沉吟了一会，不知这丫头现在在做什么。只听钟灵问道，就是实事求是：“你说我们国家要开放了，文定到里屋接电话：“你所说的应该不差：“是啊，你看现在大张旗鼓宣传的是什么，这是理论造势，，便想起了远在天边的芸芸，钟灵去准备晚餐，叹道，看来国家不开放确实是无路可走了，这些年来，有电话来找文定，赚的钱就相当于我这个县长的几年工资，难怪有这么多人挺而走险？文定道。启雷听到开放二个词，就说你吧

Figure&1-9 Java EE APIs in the EJB Container shows the availability of the Java EE 6 APIs in the application
client container.
Figure&1-10 Java EE APIs in the Application Client ContainerThe following sections give a brief summary of the technologies required by the
Java EE platform and the APIs used in Java EE applications.
Enterprise JavaBeans Technology
An Enterprise JavaBeans (EJB) component, or enterprise bean, is a body of code having fields and
methods to implement modules of business logic. You can think of an enterprise
bean as a building block that can be used alone or with other
enterprise beans to execute business logic on the Java EE server.
Enterprise beans are either session beans or message-driven beans.
A session bean represents a transient conversation with a client. When the client finishes executing, the session bean and its data are gone.
A message-driven bean combines features of a session bean and a message listener, allowing a business component to receive messages asynchronously. Commonly, these are Java Message Service (JMS) messages.
In the Java EE 6 platform, new enterprise bean features include the following:
The ability to package local enterprise beans in a WAR file
Singleton session beans, which provide easy access to shared state
A lightweight subset of Enterprise JavaBeans functionality (EJB Lite) that can be provided within Java EE Profiles, such as the Java EE Web Profile.
The Java EE 6 platform requires Enterprise JavaBeans 3.1 and Interceptors 1.1. The
Interceptors specification, which is part of the EJB 3.1 specification, makes more generally
available the interceptor facility originally defined as part of the EJB 3.0 specification.
Java Servlet Technology
Java Servlet technology lets you define HTTP-specific servlet classes. A servlet class extends
the capabilities of servers that host applications accessed by way of a request-response
programming model. Although servlets can respond to any type of request, they are
commonly used to extend the applications hosted by web servers.
In the Java EE 6 platform, new Java Servlet technology features include the
following:
Annotation support
Asynchronous support
Ease of configuration
Enhancements to existing APIs
Pluggability
The Java EE 6 platform requires Servlet 3.0.
JavaServer Faces Technology
JavaServer Faces technology is a user interface framework for building web applications. The
main components of JavaServer Faces technology are as follows:
A GUI component framework.
A flexible model for rendering components in different kinds of HTML or different markup languages and technologies. A Renderer object generates the markup to render the component and converts the data stored in a model object to types that can be represented in a view.
A standard RenderKit for generating HTML/4.01 markup.
The following features support the GUI components:
Input validation
Event handling
Data conversion between model objects and components
Managed model object creation
Page navigation configuration
Expression Language (EL)
All this functionality is available using standard Java APIs and XML-based configuration files.
In the Java EE 6 platform, new features of JavaServer Faces include the
following:
The ability to use annotations instead of a configuration file to specify managed beans and other components
Facelets, a display technology that replaces JavaServer Pages (JSP) technology using XHTML files
Ajax support
Composite components
Implicit navigation
The Java EE 6 platform requires JavaServer Faces 2.0 and Expression Language 2.2.
JavaServer Pages Technology
JavaServer Pages (JSP) technology lets you put snippets of servlet code directly into
a text-based document. A JSP page is a text-based document that contains two
types of text:
Static data, which can be expressed in any text-based format such as HTML or XML
JSP elements, which determine how the page constructs dynamic content
For information about JSP technology, see the The Java EE 5 Tutorial at .
The Java EE 6 platform requires JavaServer Pages 2.2 for compatibility with earlier
releases, but recommends the use of Facelets as the display technology in new
applications.
JavaServer Pages Standard Tag Library
The JavaServer Pages Standard Tag Library (JSTL) encapsulates core functionality common to many
JSP applications. Instead of mixing tags from numerous vendors in your JSP applications,
you use a single, standard set of tags. This standardization allows you to
deploy your applications on any JSP container that supports JSTL and makes it
more likely that the implementation of the tags is optimized.
JSTL has iterator and conditional tags for handling flow control, tags for manipulating
XML documents, internationalization tags, tags for accessing databases using SQL, and commonly used
functions.
The Java EE 6 platform requires JSTL 1.2.
Java Persistence API
The Java Persistence API (JPA) is a Java standards-based solution for persistence. Persistence
uses an object/relational mapping approach to bridge the gap between an object-oriented model
and a relational database. The Java Persistence API can also be used in
Java SE applications, outside of the Java EE environment. Java Persistence consists of
the following areas:
The Java Persistence API
The query language
Object/relational mapping metadata
The Java EE 6 platform requires Java Persistence API 2.0.
Java Transaction API
The Java Transaction API (JTA) provides a standard interface for demarcating transactions. The
Java EE architecture provides a default auto commit to handle transaction commits and
rollbacks. An auto commit means that any other applications that are viewing data
will see the updated data after each database read or write operation. However,
if your application performs two separate database access operations that depend on each
other, you will want to use the JTA API to demarcate where the
entire transaction, including both operations, begins, rolls back, and commits.
The Java EE 6 platform requires Java Transaction API 1.1.
Java API for RESTful Web Services
The Java API for RESTful Web Services (JAX-RS) defines APIs for the development
of web services built according to the Representational State Transfer (REST) architectural style.
A JAX-RS application is a web application that consists of classes packaged as
a servlet in a WAR file along with required libraries.
The JAX-RS API is new to the Java EE 6 platform. The
Java EE 6 platform requires JAX&RS 1.1.
Managed Beans
Managed Beans, lightweight container-managed objects (POJOs) with minimal requirements, support a small set of
basic services, such as resource injection, lifecycle callbacks, and interceptors. Managed Beans represent a
generalization of the managed beans specified by JavaServer Faces technology and can be
used anywhere in a Java EE application, not just in web modules.
The Managed Beans specification is part of the Java EE 6 platform specification
(JSR 316).
Managed Beans are new to the Java EE 6 platform. The Java
EE 6 platform requires Managed Beans 1.0.
Contexts and Dependency Injection for the Java EE Platform (JSR 299)
Contexts and Dependency Injection (CDI) for the Java EE platform defines a set
of contextual services, provided by Java EE containers, that make it easy for
developers to use enterprise beans along with JavaServer Faces technology in web applications.
Designed for use with stateful objects, CDI also has many broader uses, allowing
developers a great deal of flexibility to integrate different kinds of components in
a loosely coupled but type-safe way.
CDI is new to the Java EE 6 platform. The Java EE
6 platform requires CDI 1.0.
Dependency Injection for Java (JSR 330)
Dependency Injection for Java defines a standard set of annotations (and one interface)
for use on injectable classes.
In the Java EE platform, CDI provides support for Dependency Injection. Specifically, you
can use DI injection points only in a CDI-enabled application.
Dependency Injection for Java is new to the Java EE 6 platform. The
Java EE 6 platform requires Dependency Injection for Java 1.0.
Bean Validation
The Bean Validation specification defines a metadata model and API for validating data
in JavaBeans components. Instead of distributing validation of data over several layers, such
as the browser and the server side, you can define the validation constraints
in one place and share them across the different layers.
Bean Validation is new to the Java EE 6 platform. The Java
EE 6 platform requires Bean Validation 1.0.
Java Message Service API
The Java Message Service (JMS) API is a messaging standard that allows Java
EE application components to create, send, receive, and read messages. It enables distributed
communication that is loosely coupled, reliable, and asynchronous.
The Java EE 6 platform requires JMS 1.1.
Java EE Connector Architecture
The Java EE Connector architecture is used by tools vendors and system integrators
to create resource adapters that support access to enterprise information systems that can
be plugged in to any Java EE product. A resource adapter is a
software component that allows Java EE application components to access and interact with
the underlying resource manager of the EIS. Because a resource adapter is specific
to its resource manager, a different resource adapter typically exists for each type
of database or enterprise information system.
The Java EE Connector architecture also provides a performance-oriented, secure, scalable, and message-based
transactional integration of Java EE based web services with existing EISs that can
be either synchronous or asynchronous. Existing applications and EISs integrated through the Java
EE Connector architecture into the Java EE platform can be exposed as XML-based
web services by using JAX-WS and Java EE component models. Thus JAX-WS and
the Java EE Connector architecture are complementary technologies for enterprise application integration (EAI) and
end-to-end business integration.
The Java EE 6 platform requires Java EE Connector architecture 1.6.
JavaMail API
Java EE applications use the JavaMail API to send email notifications. The JavaMail
API has two parts:
An application-level interface used by the application components to send mail
A service provider interface
The Java EE platform includes the JavaMail API with a service provider that
allows application components to send Internet mail.
The Java EE 6 platform requires JavaMail 1.4.
Java Authorization Contract for Containers
The Java Authorization Contract for Containers (JACC) specification defines a contract between a
Java EE application server and an authorization policy provider. All Java EE containers
support this contract.
The JACC specification defines java.security.Permission classes that satisfy the Java EE authorization model.
The specification defines the binding of container-access decisions to operations on instances of
these permission classes. It defines the semantics of policy providers that use the new
permission classes to address the authorization requirements of the Java EE platform, including
the definition and use of roles.
The Java EE 6 platform requires JACC 1.4.
Java Authentication Service Provider Interface for Containers
The Java Authentication Service Provider Interface for Containers (JASPIC) specification defines a service
provider interface (SPI) by which authentication providers that implement message authentication mechanisms may
be integrated in client or server message-processing containers or runtimes. Authentication providers integrated through
this interface operate on network messages provided to them by their calling containers.
The authentication providers transform outgoing messages so that the source of each message
can be authenticated by the receiving container, and the recipient of the message
can be authenticated by the message sender. Authentication providers authenticate each incoming message and
return to their calling containers the identity established as a result of the
message authentication.
JASPIC is new to the Java EE 6 platform. The Java EE
6 platform requires JASPIC 1.0.
