使用无状态会话EJB组件
另一方面,无状态的服务器端组件不那么复杂,很容易跨进行负载平衡的服务器进行设计、编写和分布。
Stateless server-side components, on the other hand, are less complicated to design, write, and distribute across load-balanced servers.
其中您想要避免的最大的麻烦是无意间公开的无状态的请求-响应范例,但该范例是基于组件的框架,比如jsf,所想要隐藏的。
The biggest headache of all, and the one you really want to avoid, is the unintended exposure of the stateless, request-response paradigm that a component-based framework like JSF is intended to hide.
例如,sca导出组件会带来一个生成的无状态会话ejb。
For example, an SCA export results in a generated Stateless Session EJB.
使用无状态页面和组件,可以扩展到非常大规模的用户数。
Scale to extremely large Numbers of users with stateless pages and components.
这些方面的考虑将使您转向Web服务 /SOA框架,通过无状态EJB组件把各种服务和业务流程公开为 Web 服务。
These considerations should point you toward a web services/SOA framework, with your various services and business processes exposed as web services via stateless EJB components.
REST应用程序存在一个更重要的组件:RESTful应用程序应该是无状态的。

通过使用 WSAD中支持的Web服务向导,我们能够很容易地生成所需的构件来将我们的计算器服务无状态的会话EJB组件作为 Web 服务公开。

在CustomerSession中定义的方法,将调用无状态会话ejb组件的方法(这个bean起到一个外观(facade)的作用),例如OrderService,从而调用EIS上的事务。

有状态会话bean的池不能象无状态EJB组件的池那样用来容纳任何客户机请求。
A pool of stateful session beans cannot be used to accommodate any client request the way that a pool of stateless EJB components can.
以上示例演示了CSP的复合语言——即如何用Parallel构造把细致的无状态的组件组成分层的网络。
The above examples demonstrate the compositional semantics of CSP — namely how the Parallel construct can be used to compose layered networks from fine-grained stateless components.
