Thanks, Dan et al. StatementFinalizer is exactly what I was looking for. A quick look at the source code<http://javasourcecode.org/html/open-source/tomcat/tomcat-7.0.29/org/apache/tomcat/jdbc/pool/interceptor/StatementFinalizer.java.html> reveals exactly what I needed to know: statements are stashed away and individually closed on Connection.close(). -Igor.
