java - EntityManages NullPointerException, eclipselink + tomee + Jersey + Derby -
i new jpa, ejb , rest topic , wanted make simple crud app. when use entitymanagerfactory entities derby problem starts when want use transactions persisting objects. when try inject entitymanager nullpointerexception. i've seen several topic @ stackoverflow similar problems apparently cannot solve problem.
i want run app , focus on persistence concept , not spent few days trying set up. don't know why cannot provide datasource in web-inf/resources.xml (warning - failed register in jmx: javax.naming.namenotfoundexception: name "resource/crud/localdb" not found.)

first of remove javax.persistence.jdbc. properties , configure localdb in conf/tomee.xml datasource configuration belongs to.
then npe think lookup name reference @ injection point not right, remove name, if type enough injection no need precise it
