I just found the answer from a co-worker.
For the object I want to serialize and send via
a Mina ByteBuffer. I have to use writeObject
in the writeExternal func instead of write.
public void writeExternal(ObjectOutput out) {
byte[] bs = data.getBytes();
// Works!
out.writeObject(bs);
// Fails! Always capped by 1024 bytes
//out.write(bs, 0, bs.length);
}

There's no difference in sending just a byte buffer and sending a byte
buffer which contains an object. It's just a byte buffer from the
viewpoint
of MINA. Could you give us the previous code when you were not using
ByteBuffer.putObject()? The source code of receiving application would
help
us, too. And let us know which version of MINA you are using.
