在客户端用HTTPcookie或者隐藏表单字段存储会话状态有很大的安全风险——它将应用程序的一部分内部内容暴露给了非受信任的客户层。
Storing session state in the client using HTTP cookies or hidden form fields has significant security risks — it exposes a part of your application internals to the untrusted client layer.
该应用程序包括一个无状态会话Bean，由一个简单的Web客户端使用。

A pool of stateful session beans cannot be used to accommodate any client request the way that a pool of stateless EJB components can.
无状态会话bean不维护任何两次方法调用(它提供的服务)之间的状态，但有状态会话bean维护与客户机有关的状态。

在无状态会话bean上下文外部的客户机层中使用编程事务时，您不需要设置事务类型。
When you use programmatic transactions in the client layer outside of the context of a stateless session bean, you don't need to set the transaction type.
通过使用一个客户机cookie，我们可以跟踪客户机会话的缓存状态。
We can track the cached state of the client session by using a client cookie. Listing 1 puts it together
有状态会话bean维护客户机的“会话状态”，适合处理那些跨越多个客户机请求的任务。
Stateful session beans maintain a "conversational state" with the client and are good for sets of related tasks that span multiple client requests.
无状态会话bean用于那些为单一客户机请求提供服务的业务逻辑任务。
Stateless session beans are used for business-logic tasks that service a single request from client code.
IBMRecordsManagerAPI包含一些用于客户机的有状态会话bean。

In this example Web application, the client (a JSP page in the Web tier) holds a reference to, and calls methods on, an instance of the CustomerSession stateful session EJB component.
有状态会话bean保存特定客户机调用之间的信息。
A stateful bean preserves information between invocations from a specific client.
由于无线网络的有限带宽，而且多数无线网关不支持“cookie”，所以将用户会话状态从服务器端推入到客户端是不太可能的。
Due to the limited bandwidth on the wireless network and the lack of support for "cookies" in most wireless gateways, it is not possible to push the user's session state from the server to the client.
