How to get Object from MQTT message payload

Question

On receiving mqtt message I am trying to get Object from payload (byte[])

Object ob = SerializationUtils.deserialize(message.getPayload());

I am getting:

org.apache.commons.lang.SerializationException: java.io.StreamCorruptedException: invalid stream header: 7B22736E
    at org.apache.commons.lang.SerializationUtils.deserialize(SerializationUtils.java:168)
    at org.apache.commons.lang.SerializationUtils.deserialize(SerializationUtils.java:193)

How did you write the object in that message? It does not look like a serialized Java object. — eckes, Aug 28 '16 at 18:18

You need a JSON parser not the Apache Commons Serialization library.

Something like the JSON.org parser

JSONObject obj = new JSONObject(msg.toString());
