In my sql ,I built a database called oko which is made up on table
with ID,firstname and Lastname, this is just for testing purposes.
in My netbeans i built a web app called AGAIN

Oko.java"
i built restful web service from entity class "Oko.java";
i used glassfish server 3.2.
when i tested the restful webservice it work pretty well.
i was very happy with this !!.
SECOND :
Now i tried to do thesame thing with my apache TomeePlus server ,
but it is not working .

Re: tomee+ and restful webservice
Posted by "John D. Ament" <jo...@gmail.com>.
I would start on line 40 of this class:
java.lang.NullPointerException
at service.AbstractFacade.findAll(AbstractFacade.java:40)
at service.OkoFacadeREST.findAll(OkoFacadeREST.java:66)
Since you're getting a null pointer.
