There is a set of methods in JTA which "packages" your traditional JDBC calls into the Two-Phase-Commit protocol.
JTA中有一组方法，它将传统的JDBC调用封装到了两阶段提交（Two-Phase-Commit）协议中。
11
Use local transactions if you don't need to use JTA because JTA requires many more resources and is much slower than local transactions.
如果不需要JTA就用本地事务，因为JTA需要更多资源，比本地事务更慢。
12
Always remember that XA connections are participating in a JTA transaction.
一定要记住XA连接参与了JTA事务。
13
Updates to the cache and the database are wrapped in the same JTA transaction so that the cache and database are always synchronized.
对缓存和数据库的更新被包装在同一个JTA事务中，这样缓存与数据库总是保持同步的。
14
To demarcate a transaction with JTA, the application invokes methods on the javax. transaction. UserTransaction interface.
要用JTA进行事务界定，应用程序要调用javax.transaction.UserTransaction接口中的方法。
15
