I am looking for simple-to-use embeddable Open-source Object-oriented database for Java desktop application.
I am working on small portable Java app with embedded database. Originally I was thinking of using SQLite or H2 with JPA. However I am not the 100% sure that the data scheme will not change over time and I am already working with Objects so I might save some trouble by using ODBMS right away.
Maven repository and GUI would be appreciated.
