There must be a persistence.xml file in the WEB-INF/lib/*.jar. META-INF/persistence.xml is not the right place to package persistence.xml in a war, so it being ignored by GlassFish. You should package it as WEB-INF/classes/META-INF/persistence.xml or META-INF/persistence.xml in any of jar in WEB-INF/lib/.
