大佬教程收集整理的这篇文章主要介绍了连接与托管连接无关.org.jboss.resource.adapter.jdbc.jdk6.WrappedConnectionJDK6，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
自从您一年前提出这个问题以来，这个答案实际上可能为时已晚。但它将帮助将来会遇到此错误的人。
您的错误可能来自不同的来源，但在我的情况下，它的所有原因均与事务超时有关，某些查询可能需要很长时间，因此超时已到，hibernate会引发异常。在我的情况下，我将事务超时设置为更高的值。这解决了我的问题。
这是一个有用的链接。 交易不活跃！
了解JDBC内部超时配置

我在JBoss服务器上使用Hibernate。我得到下面的错误。
当我尝试在同一会话中第二次连接到数据库时，发生错误。
另外，我还会收到错误消息“为您关闭连接。请关闭您的连接”。
