Hi, I am using JBoss 4.2.2 with jdbc3.(jcon3.jar) For some operations that access a database I have this error: | 2008-03-12 13:14:53,653 INFO [org.jboss.resource.connectionmanager.CachedConnectionManager] Closing a connection for you. Please close them yourself: org.jboss.resource.adapter.jdbc.WrappedConnection@3324df | I found a previous post in this forum. http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3846334#... As stated in that forum I have added to my -ds.xml the following: | <track-statements>false</track-statements> | And now it seems not to happen, at least as far as I have tested. I ask again because my JBoss version is the JBoss 4.2.2 and I wonder if this is something that should be fixed. By the way, before moving to jdbc3 I did not have this problem. Maybe is there some problem with 4.2.2. and jdbc3? some configuration issue I have skipped? What puzzles me is that it only happens with certain database accesses, not all the time. thanks in advance!
