Light weight alternative to Hibernate? [closed]

Answer 1

My ORMLite library is one such alternative. It supports MySQL, Postgres, Microsoft SQL Server, H2, Derby, HSQLDB, and Sqlite, and can be easily extended to others. It uses annotations to configure classes, good Spring support, flexible query builder, etc..
