[JPA] Logging in Oracle Application Server

Question

Hi,
I have a problem that the logging of SQL statements is lost in an application deployed in OAS 10.1.3.1.
I have set the following property in persistence.xml:
    <property name="toplink.logging.level" value="FINER"/>In Java SE and in the standalone OC4J, the SQL is printed in the console window. However, when deployed in the Oracle Application Server, the SQL statements are lost. They are not in the standard server's log file in $ORACLE_HOME/opmn/logs/ default_group~home~default_group~1.log where the rest of the log data can be found.
Can anybody tell me if there's anything special about JPA logging in OAS?
We currently use TopLink Essentials v2.0-b58g (RC8) but we have also tried with other versions and there's no SQL info in the log.
Best regards,
Bisser

Thank you very much!
I tried that option too. Sadly, it didn't work.
Now I have the following in persistence.xml:
    <property name="toplink.logging.level" value="FINEST"/>
    <property name="toplink.logging.level.sql" value="FINEST"/>I re-deployed the application. I even restarted the server. But nope, nothing helped. TopLink Essentials doesn't print to the standard console log and I don't know if it prints anywhere at all (and if it does, where?).
Through the server's administration console, I can see the following in the "Logger configuration":
oracle.toplink.essentials.session.file:/u01/app/oracle/product/10.1.3.1/OracleAS_1/j2ee/home/applications/asmPreview/asmModel.jar-ASM:  FINEST
    oracle.toplink.essentials.session.file:/u01/app/oracle/product/10.1.3.1/OracleAS_1/j2ee/home/applications/asmPreview/asmModel.jar-ASM.sql:  FINEST
.Previously, the latter was NULL, which meant that it was inheriting from its parent log. But now it's explicitly set to "FINEST" and yet it doesn't print anything.
I wish I could force it to print somehow. That would aid us a lot in the functional testing, when we see strange behavior.
