什么是SDP-会话描述协议？

Session notes: Enter short notes describing observed session details, such as tool analysis results and session information.
在两种情况下，每个会话bean (Task或Service)的部署描述符仅仅包括他所实际使用的每个会话bean的EJB - REF。
In either case, the deployment descriptor for each session bean (Task or Service) simply includes an EJB-REF for each session bean that it actually USES.
而且因为我们描述的是自动化测试执行系统，而不是手动系统，所以参与者仅需建立与正运行的实例的直接远程桌面协议(rdp)会话。
(And since we're describing an automated test execution system instead of a manual one, participants rarely need to establish a direct remote desktop protocol (RDP) session with running instances.)
它描述了通过一个可以更新jdbc和JMS数据的简单会话ejb来实现xa事务。
It described a simple session EJB method that updates both JDBC and JMS data, necessitating an XA transaction.
WAR文档的部署描述符现在需要引用这个会话ejb。

具有容器管理事务方法的无状态会话bean，如清单5和清单6所描述的，降低了管理数据库实体的复杂性。
The stateless session bean with container-managed transactional methods, as described in Listing 5 and Listing 6, reduce the complexity involved with managing database entities.
我们已经描述了两个典型的Web应用程序技术漏洞：会话控制和劫持漏洞，以及注入漏洞。

如果Domino服务器被迫承担超出合理范围的压力，就可能产生严重的后果，上面描述的未经身份验证的会话问题就是这种问题的示例。
The unauthenticated session problem just described is an example of an outcome that can result if a Domino server is forced to go beyond reasonable expectations.
清单1显示了一个交互式会话，这里使用了刚才所描述的dumps和loads函数。
Listing 1 shows an interactive session using the dumps and loads functions just described.
无状态会话Bean的声明式事务设置可以在ejb部署描述符(ejb - jar . xml)中完成。
The declarative transaction Settings for the stateless session bean are done in the ejb deployment descriptor (ejb-jar.xml).
因为我们将在运行这个应用程序时从Web项目中引用会话beanHelloWorldSession，所以我们必须把EJB引用添加到 Web模块部署描述符中。
Since we will be referencing the session bean HelloWorldSession from the Web project when running the application, we have to add an EJB reference to the Web module deployment descriptor.
现在双方都有了“mastersecrets”，规约描述了我们如何生成会话所需的所有的密钥，我们需要使用PRF函数来创建一个“keyblock”，然后从这个块中提取所需的密钥？
Now that both sides have a "master secrets", the spec shows us how we can derive all the needed session keys we need using the PRF to create a "key block" where we will pull data from.
在ejb - jar . xml部署描述符中可以看到新会话bean的描述，如清单1所示。
