Log Oracle SQL statements with Squeryl and Play 2

Question

I am trying to log the SQL produced by Squeryl in a Play 2 application, for debugging purposes. I am using this with the following Oracle logging properties:

.level=SEVERE
oracle.jdbc.level=FINE
oracle.jdbc.handlers=java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level=ALL
java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter
oracle.net.ns.level=FINEST
oracle.net.ns.handlers=java.util.logging.ConsoleHandler

This has worked for me before in a non-Play application with the same Oracle driver jar, but in a Play application, the JUL-to-SLF4J bridge seems to be causing a problem:

Oops, cannot start the server.

I tried simply removing the JUL to SLF4J bridge jar from my deployed application, but Play refuses to start if that jar isn't present, so that didn't work.

I obviously don't need to use this particular approach, I just want some way to log the SQL selects being executed (preferably without admin access to the Oracle server).

Answer 1

I just needed to change the oracle.net.ns.level to SEVERE. Logging of oracle.net is only needed if you want to log the network packets being sent to and from the server, which I didn't need in this case.
