We've seen how the EJB extensions file defines the relationship roles, and how these roles may map to attributes in the EJB DD.

我们已经知道EJB扩展文件如何定义关系角色以及这些角色可能如何映射到EJBDD中的属性。

To understand how the extensions file works, let's first present part of the standard EJB 1.1 DD for our example (some parts have been removed for clarity — they are described below).

要理解扩展文件的工作原理，首先让我们介绍一下用于我们示例的部分标准e JB 1.1DD(为清晰起见除去了某些部分？它们将在下面描述)。

After the two commands, the file state.YYYY-MM-DD, such as state.2007-08-05, is created with contents similar to this.

在执行了这两个命令之后，创建了文件state . YYYY - MM - DD，如state . 2007-08-05，其内容与以下所示类似。

Dd is a file system copy utility that makes binary copies of file systems.

dd是一个文件系统复制实用工具，它产生文件系统的二进制副本。

However, dd is not file based, so you can only restore data to an identical hard drive partition.

然而，dd不是基于文件的，因此您只能使用它来将数据还原到完全相同的硬盘驱动器分区。

The trick is that the deployment plan adds the information (in the alt-dd element) that the mysql-plan.xml file USES to provide the connector configuration.

这里的关键是，部署计划中添加了mysql - plan . xml文件，以提供连接器配置的信息(在alt - dd元素中)。
