Should I use CDI SessionFactory injection or Hibernate SessionFactory?

Hi expert,

I'd like to seek your advice as to what is the best solution for my problem.



I'd like to know for the session portion, is it best to use EJB session or just simply stick to Hibernate SessionFactory?

However, to change to EJB I'd have to install TomEE and I am not sure if it is cheap for hosting plus I'd have to deal with all the mechanism of TomEE from scratch

For the above code, Eclipse is pointing to the error :


java.lang.NullPointerException
at Business.RegisterService.isTutorExists(RegisterService.java:82)
at Business.RegisterService.register(RegisterService.java:20)




Or is there something wrong with the above code ?
