Making EclipseLink Logging Play Nice With GlassFish 3.1.2.2

To get logging working properly with EclipseLink 2.3.2 and GlassFish 3.1.2.2, you want to configure the actual logging values in GlassFish’s logging.properties file, not in your META-INF/persistence.xml file.  You have to set two levels (a bit mysterious, as one is a child of the other; setting values on the parent logger should cause them to flow downhill, but for some reason they do not).

Then, to be able to see SQL parameters in the output, you have to set a property in your META-INF/persistence.xml file.

Assuming you have a domain called domain1:

  • Edit $GLASSFISH_HOME/glassfish/domains/domain1/config/logging.properties and add the following lines:
    1. org.eclipse.persistence.level = FINE
    2. org.eclipse.persistence.sql.level = FINE
      • The first allows you to see SQL statements.  The second must be set in order for SQL parameters to be seen, but it is not sufficient on its own.
  • In your META-INF/persistence.xml, add the following element as a child of the <properties> element:
    <property name="eclipselink.logging.parameters" value="true"/>
