I'm currently searching for a really easy way to get simple Java Objects persistent in Databases and/or XML and/or other types of data stores.
For big projects in the company i would use hibernate, ibatis, datanucleus or something like that. But with small private projects this will take over 80% of the worktime.
I also found "simpleORM" but this one requires to code data-related stuff pretty hardly into the data-model classes. I don't really like that style so this is no option for me.
Do you have a suggestion for some library which simply takes my objects and saves / loads them as they are or with very little configuration?

Hibernate is a Java persistence framework that simplifies the development of Java application to interact with the database. It is an open source, widely used, lightweight, ORM tool.
There are several persistent frameworks and ORM options in Java. A persistent framework is an ORM service that stores and retrieves objects into a relational database.
Object-relational mapping (ORM) is a programming technique in which a metadata descriptor is used to connect object code to a relational database. Object code is written in object-oriented programming (OOP) languages such as Java or C#.
ORM sits in between your application and JDBC providing the missing link between the object oriented model and relational database model of programming. In fact this so called ORM interacts with the JDBC to talk to the database ultimately.
You could try my ORMLite library, which was designed as a simple replacement for hibernate and iBatis. I'm the main author. It supports a number of JDBC databases and has an Android backend. Here is the getting started section of the manual which has some code examples. Here also are working examples of simple usage patterns.
