[编辑] 原则

它的灵感源自下列原则:

  • 只有一种“工具”
  • 将JSF与EJB 3.0整合
  • 集成Ajax
  • 将业务流程作为首要的基础建筑
  • 声明式状态管理
  • Bijection(双向注入)
  • 工作区管理(Workspace Management)和多窗口浏览
  • 更喜欢XML注解
  • 集成测试轻而易举
  • 规范也非尽善尽美
  • Web应用程序不只是服务HTML页面

[编辑] Functions

Jboss seam architecture.png
  • Integrate JSF with EJB 3.0
  • Integrated AJAX
  • Integrate BPM: jBPM
  • Seam component
  • Declarative State Management
  • Bijection
  • Workspace Management
  • Annotated POJOs Everywhere
  • Testability as a Core Feature
Configuring Seam in Java EE 5

[编辑] Seam contexts

  • Stateless context
  • Event (or request) context
  • Page context
  • Conversation context
  • Session context

In a JSR-168 portal environment, the session context represents the portlet session.

  • Business process context
  • Application context

Seam stores its own configuration and metamodel in the application context.

[编辑] Seam component types

  • EJB 3.0 stateless session beans
  • EJB 3.0 stateful session beans
  • EJB 3.0 entity beans
  • JavaBeans
  • EJB 3.0 message-driven beans

[编辑] Seam events

  • JSF events
  • jBPM transition events
  • Seam page actions
  • Seam component-driven events
  • Seam contextual events

[编辑] Pageflow in Seam

There are two ways to define pageflow in Seam:

  • Using JSF navigation rules - the stateless navigation model
  • Using jPDL - the stateful navigation model

[编辑] install guide

Seam 2.0是针对JavaServer Faces 1.2开发的,所以我们推荐在JBoss 4.2下使用Seam,因为它包含了JSF 1.2参考实现。

  • Ensure that you have JDK 5.0 or above and Ant 1.6 properly installed (not Ant 1.7 beta).
  • For Seam 1.1.0.GA, download JEMS installer 1.2.0.BETA3 and install JBoss AS 4.0.5 with the ejb3 profile selected. Do not install any other version of JBoss, and do not try to install JBoss using any other profile, not even the Shakespeare and his quotes all profile.
  • Start JBoss AS with the bin/run.(sh|bat) script.
  • Download Seam and unpack it.
  • Edit build.properties in your Seam directory and configure the path to your JBoss AS installation directory.
  • In the jboss-seam/examples/booking directory, type ant deploy and check for any error messages.
  • Point your browser to http://localhost:8080/seam-booking/ and register an account.
  • In the jboss-seam/examples/dvdstore directory, type ant deploy and check for any error messages.
  • Point your browser to http://localhost:8080/seam-dvd/ and register an account.
  • In the jboss-seam/examples/issues directory, type ant deploy and check for any error messages.
  • Point your browser to http://localhost:8080/seam-issues/ and register an account.
  • Change the pages and/or source code in your the jboss-seam/examples/booking directory and redeploy the application by calling ant deploy - see how your modifications affect the application.
