I am developing a Java Desktop Application but have some confusions in choosing a technology for my persistence layer.

Till now, I have been using JDBC for DB operations. Now, Recently I learnt Hibernate and JPA but still I am a novice on these technologies.

Now my question is What to use for my Java Desktop Application from the following?

  • JPA

  • Hibernate

  • JDBC

  • DAO

  • any other suggestion from you...

I know that there is no best choice from them and it totally depends on the complexity and the requeirements of the project so below are the requirements of my project

  1. It's not a complex application. It contains only 5 tables (and 5 entities)
  2. I wan't to make my code flexible so that I can change the database later easily
  3. The size of the application should remain as small as possible as I will have to distribute it to my clients through internet.
  4. It must be free to use in commercial development and distribution.

On the basis of the below answers, I would like to go with JPA so as to prevent myself from writing vendor-specific SQL code.

But I have some problems in JPA which are mentioned at Java Persistence API

java hibernate jpa jdbc dao
