Imagine having a tool that can automatically detect if you are using JPA and Hibernate properly. Hypersistence Optimizer is that tool!

  1. Hi Vlad,

    Hope you are having a great weekend! I was wondering if you are available for 30min-1hour consultation and how much would it cost. I am fairly new to Spring /JPA2/Hibernate and I am struggling a bit on creating a OnetToMany relationship where null can be a possibility (the relationship should be optional). I am having troubles even listing both objects by invoking the parent entity service. The session dies before invoking the second object, I thought JPA can handle that. I ran into something similar before and fixed in one of my training courses,but it was a while ago. I read one of your articles, but still struggling. Thank you, Gabriel.
