[jboss-user] [Javassist Users] - Instrumenting SQL execution times (Statement and PreparedSta

Hello, Does anyone have any clues as to how its possible to instrument JDBC SQL query times ? I have successfully been able to instrument other classes, but I am unable to find the class that actually executes the Query. I have tried, for each class loaded in the classloader, to looks at its implementations to check if one the class implements either java.sql.Statement or java.sql.PreparedStatement. If thats not the case, I check the superclass for up to 10 levels. The application uses DBCP, and the following classes gets instrumented: java.sql.PreparedStatement java.sql.CallableStatement org.apache.commons.dbcp.DelegatingPreparedStatement org.apache.commons.dbcp.DelegatingStatement org.apache.derby.iapi.jdbc.EnginePreparedStatement org.apache.derby.iapi.jdbc.EngineStatement However, none of these classes seems to fire off the actual execute(), executeQuery() or executeUpdate methods - at least the instrumentation times do not get returned as expected. Is there a good strategy to be able to instrument JDBC ? My main goal here is to be able to store the execution times per. SQL that is ran through the system.
