Jaav supports serialisation naturally, you don't need any library to do it. All you have to do is say that a class implements serializable.

Then to serialise to disc, you can do something simple like:

Code:

import java.io.*;

// serialise an object to disc..

FileOutputStream f=new FileOutputStream(dataPath("data.ser"));
ObjectOutputStream o=new ObjectOutputStream(f);
o.writeObject(MyObj);
o.close();

// read it back in

FileInputStream f=new FileInputStream(dataPath("data.ser"));
ObjectInputStream o=new ObjectInputStream(f);
MyClass MyObj=(MyClass)o.readObject();
o.close(); 

It should be noted however that you can't necessarily serialise everything, as some pre-packaged classes may not have declared "implements serializable" and so you'll not be able to serialize them.
