I have written a JCA connection factory which works fine. I use it in a stateful session bean. On first use I always get | 2007-06-15 18:39:42,746 TRACE [org.jboss.resource.connectionmanager.CachedConnectionManager] popped object: org.jboss.resource.connectionmanager.CachedConnectionManager$KeyConnectionAssociation@5522e1 | 2007-06-15 18:39:42,746 INFO [org.jboss.resource.connectionmanager.CachedConnectionManager] Closing a connection for you. Please close them yourself: com.Connection@ec76fa | java.lang.Throwable: STACKTRACE | at org.jboss.resource.connectionmanager.CachedConnectionManager.registerConnection(CachedConnectionManager.java:290) | at org.jboss.resource.connectionmanager.BaseConnectionManager2.allocateConnection(BaseConnectionManager2.java:417) | at org.jboss.resource.connectionmanager.BaseConnectionManager2$ConnectionManagerProxy.allocateConnection(BaseConnectionManager2.java:842) | | Now my question is why? I have not called close on the connection for a reason - I want the bean to reuse it. What is going on here? I return the connection to the pool when I am done with it but jboss appears to try to pre-empt this. How do I fix this? thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4054851#...
