开发了EJB后，程序员必须设置定义各种特征(如ejb的事务支持和隔离级别)的部署描述符。
After developing an EJB, the programmer must set deployment descriptors that define characteristics, such as transaction support and isolation levels for the EJB.
因为EJB的事务隔离级别是在部署描述符中设置的，所以具有不同事务隔离级别的不同应用程序可以重用同一个EJB。
Because the EJB's transaction isolation level is set in its deployment descriptor, the same EJB could be reused in different applications with different transaction isolation levels.
虽然示例中使用的资源适配器不响应J2EE事务性隔离级别设置的变化，但是某些围绕关系数据库系统构建的EIS确实可能会受到影响。
Although resource adapters used in the example do not respond to changes in J2EE transactional isolation level Settings, some EISs built around relational database systems may be affected.
