you could use a Byte Array ObJect stream, then send the resulting
byte[].

Your objects had better not be attached to too much or they won't fit
in a packet.

No because UDP cannot guarantee delivery.

Plus a TCP connection is like a stream - but UDP are just individual
packets.

However if you can serialize your class and make it smaller than a single
packet you shouldn't have trouble just inserting the info into a UDP packet
and sending away.

Hi,

The MAIN difference between TCP and UDP is that UDP DOES NOT insure you
that received packets are in the proper order. If you want to use UDP
to send objects, you can BUT you must do the following on server-side :
    a) Break your byte array to 512 bytes chunks for example
    b) Add a header to each packet giving the sequence number (the
ordinal number of the packet) and the global number of packet
    c) Add some code to acknwoledge each packet*
and on the client side :
    a) Re-assemble all that data that may have come not in the right
order, once all packets have arrived
    b) Aknwoledge all incoming packets

A good example inh the TFTP protocol (you can find an implementation in
jakarta Commons-Net project).

TCP also does not support passing objects.

Both are transport protocols for octets. TCP connection/oriented, UDP
connection-less. Both don't care about objects. What is it what you
really want?
