[ https://issues.jboss.org/browse/WFLY-3177?page=com.atlassian.jira.plugin.... ] Scott Marlow commented on WFLY-3177: ------------------------------------ In the wildfly/modules/system/layers/base/org/eclipse/persistence/main folder is the jipijapa-eclipselink-1.0.1.Final.jar file. Contents of jipijapa-eclipselink-1.0.1.Final.jar are: {quote} META-INF/ META-INF/MANIFEST.MF org/ org/jipijapa/ org/jipijapa/eclipselink/ META-INF/services/ org/jipijapa/eclipselink/JBossAS7ServerPlatform.class org/jipijapa/eclipselink/VFSArchive.class org/jipijapa/eclipselink/VFSArchive$1.class org/jipijapa/eclipselink/JBossAS7ServerPlatform$JBossAS7TransactionController.class org/jipijapa/eclipselink/EclipseLinkPersistenceProviderAdaptor.class org/jipijapa/eclipselink/JBossArchiveFactoryImpl.class org/jipijapa/eclipselink/JBossLogger.class META-INF/services/org.jipijapa.plugin.spi.PersistenceProviderAdaptor META-INF/maven/ META-INF/maven/org.jipijapa/ META-INF/maven/org.jipijapa/jipijapa-eclipselink/ META-INF/maven/org.jipijapa/jipijapa-eclipselink/pom.xml META-INF/maven/org.jipijapa/jipijapa-eclipselink/pom.properties {quote} In [https://github.com/jipijapa/jipijapa/blob/master/eclipselink/src/main/jav...], the "eclipselink.logging.logger" property should be set to org.jipijapa.eclipselink.JBossLogger which looks right to me.
