I use jboss4.0.2+spring1.2.8+ibatis2.x+Oracle10g I configured an xa datasource in jboss, everthing configured fine and startup without errors. But when request a function with db operation. Functions work fine but jboss has shown following errors: 20:46:01,687 INFO [CachedConnectionManager] Closing a connection for you. Plea se close them yourself: org.jboss.resource.adapter.jdbc.WrappedConnection@ 4b2f7f java.lang.Exception: STACKTRACE at org.jboss.resource.connectionmanager.CachedConnect ionManager.register Connection(CachedConnectionManager.java:321) at org.jboss.resource.connectionmanager.BaseConnectio nManager2.allocateC onnection(BaseConnectionManager2.java:467) at org.jboss.resource.connectionmanager.BaseConnectio nManager2$Connectio nManagerProxy.allocateConnection(BaseConnectionMan ager2.java:874) at org.jboss.resource.adapter.jdbc.WrapperDataSource. getConnection(Wrapp erDataSource.java:103) at org.springframework.jdbc.datasource.DataSourceUtil s.doGetConnection(D ataSourceUtils.java:112) at org.springframework.jdbc.datasource.TransactionAwa reDataSourceProxy.g etConnection(TransactionAwareDataSourceProxy.java: 107) at org.springframework.jdbc.datasource.DataSourceUtil s.doGetConnection(D ataSourceUtils.java:112) at org.springframework.jdbc.datasource.DataSourceUtil s.getConnection(Dat aSourceUtils.java:77) at org.springframework.orm.ibatis.SqlMapClientTemplat e.execute(SqlMapCli entTemplate.java:165) at org.springframework.orm.ibatis.SqlMapClientTemplat e.insert(SqlMapClie ntTemplate.java:303) at com.iBatisDaoBase.insert(iBatisDaoBase.java:22) at com.MyDaoImpl.createData(MyDaoImpl.java:10) at com.MyServiceImpl.createData(MyServiceImpl.java:18 ) at sun.reflect.NativeMethodAccessorImpl.invoke0(Nativ e Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Native MethodAccessorImpl. java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(De legatingMethodAcces sorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.springframework.aop.support.AopUtils.invokeJoi npointUsingReflecti on(AopUtils.java:287) at org.springframework.aop.framework.ReflectiveMethod Invocation.invokeJo inpoint(ReflectiveMethodInvocation.java:181) at org.springframework.aop.framework.ReflectiveMethod Invocation.proceed( ReflectiveMethodInvocation.java:148) at org.springframework.transaction.interceptor.Transa ctionInterceptor.in voke(TransactionInterceptor.java:96) at org.springframework.aop.framework.ReflectiveMethod Invocation.proceed( ReflectiveMethodInvocation.java:170) at org.springframework.aop.framework.JdkDynamicAopPro xy.invoke(JdkDynami cAopProxy.java:176) at $Proxy406.createData(Unknown Source) I saw there are some discussion on hibernate + spring run on jboss to contol the connection close on each transaction. how to configure with ibatis?
