I'm getting java.sql.SQLException: org.apache.tomcat.dbcp.dbcp.DelegatingPreparedStatement is closed.

This is occurring within a spring managed hibernate session but not consistently. That is, upon server startup, all works well for any given criteria until, for some reason it stops working and we get the exception. At that point we can reliably reproduce the exception.

I will happily post more info if needed.

Thanks for any help!
Ben

Well, I can't help too much. I'd guess that either you have some code somewhere that is committing the transaction or explicitly closing the Session. Another possibility is that you don't have your Spring-managed Sessions working correctly. Perhaps one Session that should be discarded is hanging around on a ThreadLocal variable and not being cleaned up?

I'm not sure which connection pool you are using, but perhaps there is a bug in the connection pool?
