Substitute for Ebean Server

i'm developing a plugin for a Game and it provides a version of Ebean Server, but that version is really outdated and doesn't work properly, so i'm looking for a substitute. It have to be compatible with MySQL and SQLite. Right now im doing everything manually (Create queries, load data, save data...) since i couldn't use Ebean Server, but it's very dirty because i have +25 variables to save in, and i would like to have more data stored in, any help is appreciated.
