Answer 1

if you are using IntelliJ or a maven project structure you need to place the entire "META-INF/persistence.xml" file in the in resources(src/resources) folder so that it will move your persistence.xml file into "WEB-INF/classes/persistence.xml" location.

if you are using eclipse or something else makes the changes accordingly so that it will move the file to WEB-INF/classes/persistence.xml

anything else did not work for me.
