having an exception when saving oracle type object in some entity

As we can see here you have closed connection to DB in that time when you try to setString do.
The way It is possible

  1. When you don’t create any connection to DB
  2. When you create but don’t open any connection to DB
  3. When you create and, even open, but, close connection before tries to make DML into DB.
