Null Pointer Exception when not using Spring #77

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
I just found hibernate-generic-dao, and trying to integrate it with my project. 
I'm not using Spring, and I'm getting this exception:

java.lang.NullPointerException
    at com.trg.dao.jpa.JPABaseDAO._persistOrMerge(JPABaseDAO.java:256)
    at com.trg.dao.jpa.GenericDAOImpl.save(GenericDAOImpl.java:113)

Reading the code, I understand that I haven't assigned any value to 
EntityManager. What should I assign it? Is hibernate-generic-dao tested withot 
Spring integration?

It is in fact tested without Spring integration. The stack overflow topic looks 
like it's got the right answer.

I don't believe we actually have a problem with the framework here. If it turns 
out I'm wrong about this, feel free to post again.
