可以想象，这是相当可怕的代码(例如没有事务管理)，虽然其可以正常工作。
Granted, this is pretty terrible code (no transaction management, for example), but work with me here.
对于要求普通JCR代码的应用程序，JCR模块允许用直接使用JCR API的代码，透明地使用事务驱动会话。

此外，bean开发人员实际上不需要编写任何用于处理事务的代码，比如确定何时调用commit方法以及调用失败时该如何处理。
Furthermore, the bean developer doesn't actually have to write any code for handling transactions, such as deciding when to invoke the commit method and what to do if it fails.
SQLDatastore全部使用托管代码写成，完全支持事务，并且允许用任何语言来写存储过程。
SQLDatastore is written completely in managed code, fully supports transactions, and allows stored procedures to be written in any language.
您将测试清单3中的代码，发现persist方法在没有事务的情况下不能工作。
So, you test the code in Listing 3 and discover that the persist method didn't work without a transaction.
现在，我将修复清单1中的代码，方法是应用HighConcurrency事务策略的先读取技巧。
Now I'll fix the code in Listing 1 by applying the High Concurrency transaction strategy's read-first technique.
TransactionDemo应用程序的Directlyremove Sol菜单项提供了一个例子，说明如何从Web 应用程序角度调用事务代码。
The Directly remove Sol menu item in the Transaction Demo application provides an example of how to call transaction code from the Web application's perspective.
TransactionDemo应用程序使用XDoclet代码生成器设置事务类型。
The transaction Demo application sets up the transaction type using the XDoclet code generator.
容器处理事务，因此bean开发人员不需要编写事务处理代码。
The container handles the transactions, so the bean developer doesn't need to write transaction-handling code.
在新代码中，事务持续时间只有300ms，这显著低于清单1中的6100 ms。
The transaction duration in the new code is only 300 ms, dramatically lower than the 6100 ms from Listing 1.
如表2所示，在事务作用域中执行的代码至减少至300ms。
As you can see in Table 2, the code executing within the transaction scope is reduced to 300 ms.
例如，将业务上下文信息(比如业务事务ID和授权代码)包含在SOAP消息体中。
For example, include business context information such as business transaction ids and authorization codes into the SOAP message Body.
