The lack of message set definitions, which contain details of how messages should be rendered when converted to a bitstream, require that the data be contained in the logical tree.
由于缺少消息集定义(消息集定义包含在转换到位流时应该如何呈现消息的详细信息),因此需要将数据包含在逻辑树中。
If another transaction retrieves the data and sees that the flag is set by some other user, then it will, by convention, give a warning message to the user that the data is in use.
如果另外的事务检索数据并发现标记已被其他用户设置,那么它将按约定向用户发出数据正在被使用的警告消息。
For example, a J2EE transaction could be set to retrieve a message from a JMS provider, extract data from that message, and then attempt to update the database.
例如,可以建立一个J2EE事务来从一个JMS提供者那里获取一条消息,从该消息中提取数据,并尝试更新数据库。
