1. For object collections try JDBM (one jar). Gives you a map that is stored on disk.

   DB db = new DBMaker(fileName).build();

   Map map = db.createTreeMap("mapName")

   map.put("obj1", myObject1);

2. For config JAXB is really simple and does not have dependencies. Stores in XML.

   JAXB.marshall(myObject, new File("config.xml") ); // saved. that's it
