Cannot add data to database in my web app using JSF, javaEE

Question

I tried to solve by myself but couldn't after spending so much of time and finally came here. I just want to add user's input into database but my create() method keeps getting NullPointerException. please tell me why it does and what i should do with my code. getter and setter are left out. Thanks.

Start by reading http://stackoverflow.com/questions/218384/what-is-a-null-pointer-exception-and-how-do-i-fix-it And how is this JSF related? Do you not get the value from the client? Then it is jsf related. If not, it is JPA related — Kukeltje, Oct 26 '16 at 12:43

It looks like your create() method definition does not take any parameters and yet you have a argument in the create(oci) when you use it. Try using the create() without the argument oci.

It's not linked to that because there are two methods create() and db.create(arg) – Cédric O. Oct 26 '16 at 11:45
I changed the way I understood what you said. But it still doesnt work well. Could you tell me why it doesnt...? – anonyrabbit Oct 26 '16 at 13:06
