Error Deserializing from Servlet

Question

I am sending a serialized object to my client via HTTP using a servlet.
The data appears to be sent over fine but when I try to deserialize the object I get an java.io OptionalDataException.
My code looks something like this
ObjectInputStream is=new ObjectInputStream(urlConnection.getInputStream());
SerializedObject obj=(SerializedObject)is.readObject();
The data is available on the stream, and is the same length as the bytes of the serialized object on the server.
It has something to do with BlockDataMode inside ObjectInputStream. Here is the offending source code in ObjectInputStream
private final Object readObject...
if (blockDataMode){
if (count==0)
{refill();}
if (count>0)
//this is the line which throws the exception
{throw new OptionalDataException(count);}
Thanks for your help!

Answer 1

I errored in one part of the post, the length of the object stream on the server is 862 but my client input stream has 871 bytes. Is it possible that HTTP has added something to the inputstream on the client?
