Problem on JPA Merge Entity.

Hello, I have a problem with the EntityManager.merge() function. I set a property value of an entity (statement) with an other entity (newSingleConstraint). newSingleValue is already persisted.

Entity factory - best practices

Suppose I run a website that handles services such as user registration, user login checks, etc. I have all the credentials stored in an ObjectDB. Currently, each time user sends a request, I initiate a db connection by creating entity manager factory from db on disk, get the entity manager, modify stuff, close the connections. I wonder if it is better to have an overall db manager created on server init, then provide the shared instance over all requests, instead of creating a new one every time. ... if it is better to have an overall db manager created on server init, then provide the shared instance over all requests, instead of ... one EntityManagerFactory per database during the application lifecycle, as demonstrated in the Guest Book web application ...
