You can also replace the command layer with session EJB components.

您还可以使用会话ejb组件来代替命令层。

For example, when you migrate an EAB session EJB or a navigator, the migration tool locates and converts contained command classes and record classes used by the commands.

举例来说，当您迁移eab会话ejb或导航器时，迁移工具将定位并转换所包含的由命令所使用的命令类和记录类。

However, to use the connector in a transactional context, you must call the command from an EJB.

然而，要在事务上下文中使用连接器，您就必须从ejb调用命令。
