i have microservice scheduler. timing job via rest json. followed tutorials on how add persistence.xml doesn't seem work. don't failure messages nullpointerexception entitymanager.
it doesn't create tables etc. think there problem adding persistence.xml too?
there no problem in connecting datasource. tested , seems work properly.
