OpenJPA provides configurable channel-based logging, as described in the chapter on Logging. The simplest example of enabling verbose logging is by using the following property in your persistence.xml file:

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
version="1.0">
<persistence-unit name="example-logging" transaction-type="RESOURCE_LOCAL">
<properties>
<property name="openjpa.Log" value="DefaultLevel=TRACE"/>
</properties>
</persistence-unit>
</persistence>
