I couldn t get the accepted answer to work using the Netbeans IDE  Create Table  GUI  and I m on Netbeans 8 2   To get it to working  create the id column with the following options e g     and then use  New Entity Classes from Database  option to generate the entity for the table  I created a simple table called PERSON with an ID column created exactly as above and a NAME column which is simple varchar 255  column    These generated entities leave it to the user to add the auto generated id mechanism   GENERATION AUTO seems to try and use sequences which Derby doesn t seem to like  error stating failed to generate sequence sequence does not exist   GENERATION SEQUENCE therefore doesn t work either  GENERATION IDENTITY doesn t work  get error stating ID is null   so that leaves GENERATION TABLE   Set your persistence unit s  Table Generation Strategy  button to Create   This will create tables that don t exist in the DB when your jar is run  loaded   i e  the table your PU needs to create in order to store ID increments   In your entity replace the generated annotations above your id field with the following       I also created a controller for my entity class using  JPA Controller Classes from Entity Classes  option   I then create a simple main class to test the id was auto generated i e     The result is that the PERSON ID TABLE is generated correctly and my PERSON table has two PERSON entries in it with correct  auto generated ids
