今天用JBOSS进行测试时，connect 连接关闭报错 一般情况下 jboss会自动关闭连接的，代码里面也加了关闭连接的代码 ，但是还是出现 Closing a connection for you. Please close them yourself: org.jboss.resource 。
解决方法：JBOSS 4.0以上 jboss-4.0.5.GA\server\default\deploy/jbossjca-service.xml
将文件当中的
<mbean code="org.jboss.resource.connectionmanager.CachedConnectionManager"
name="jboss.jca:service=CachedConnectionManager">
<depends optional-attribute-name="TransactionManagerServiceName">jboss:service=TransactionManager</depends>
<!-- Enable connection close debug monitoring -->
<attribute name="Debug">true</attribute>
将红色部分的true 改为false
这样jboss就不会报错了
