Hi, Just to clarify my understanding,

When I run Hbm2ddl.java, it creates gefp.ddl. Do I need to run it in the pgAdminIII first? Or should I use it as a guide and create the tables in the gefp-create.sql based on it? Because I ran my gefp.dll in pgAdmin but its id field are not auto increment even though I used the specified annotations. Feeling confused!

PostgreSQL uses sequence to generate unique ids, not auto_increment. If you run gefp.dll, it will create a sequence called "hibernate_sequence". You don't need to use that sequence directly, but if you want to learn more about sequence, you can read PostgreSQL documentation.
