Java: object to byte[] and byte[] to object converter (for Tokyo Cabinet)

I need to convert objects to a byte[] to be stored in the Tokyo Cabinet key-value store.
I also need to unbyte the byte[] to an Object when reading from the key-value store.

Are there any packages out there that will help me with this task? Or would the best solution to implement it myself?

Answer Source
public static byte[] serialize(Object obj) throws IOException {
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    ObjectOutputStream os = new ObjectOutputStream(out);
    return out.toByteArray();
public static Object deserialize(byte[] data) throws IOException, ClassNotFoundException {
    ByteArrayInputStream in = new ByteArrayInputStream(data);
    ObjectInputStream is = new ObjectInputStream(in);
    return is.readObject();
