How to wrap up multiple byte arrays in such a way that it can be serialized and used over RMI

Question

I am creating a client/server RMI application and need to search for images on the server database and return to the client multiple images.

I immediately thought to do this ArrayList<Byte []>arrayBytes = new ArrayList <Byte []>(); and return arrayBytes, I soon found that it is impossible.

Researched ByteArrayOutputStream but I do not think the support for what I'm trying to do ...

What alternative have for this?

In my understanding, an array of bytes is the same as a byte array. Do I miss something? — paolo, Jan 28 '15 at 21:43
@aioobe That's an array of arrays, which isn't what he wants. — mbomb007, Jan 28 '15 at 21:46
You need to be specific about what form is your input an what form is your output. `byte[]` is something entirely different from `Byte[]` which is entirely different from `ArrayList` which is entirely different from `ArrayList`. — Hot Licks, Jan 28 '15 at 21:47

@mbomb007, are you sure? He says he wants to return multiple images. That sounds like a `List` to me. — aioobe, Jan 28 '15 at 21:50

You're probably after ArrayList<byte[]>. (You don't need to use Byte as component type for the array. byte[] is an Object.)

You can't do new ArrayList<byte>[]. Perhaps that's what confused you.
