    Hi, Peter Schröder!

    Ah thank you! with the addition of ByteArrayOutputStream it is very easy:

    //writing:
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    ObjectOutputStream oos = new ObjectOutputStream(baos);
    oos.writeObject(new BitSet());
    oos.close();
    byte array[] = baos.toByteArray();
    writeProperty(BIT_SET_PROPERTY, array);

    //reading:
    ByteArrayInputStream bais = new
            ByteArrayInputStream((byte[])readProperty(BIT_SET_PROPERTY));

    ObjectInputStream o = new ObjectInputStream(bais);
    BitSet date = (BitSet) o.readObject();

    //is closing necessary: (?)
    o.close();

    Thank you again and sorry for this not-cayenne-related question,

    Peter Karich.
