Hi, I wanna make an app server/client context and I wanna send to the server
a message like
Hi,
"BROADCAST " + SerializableObject
if its possible can you explain how can I do that or can you give me any
suggestion about sending Serialized Object without any conclusion sendng
only text message.
This is obviously possible, but you will have to decode yourself the
message, as you are mixing text and binary content.
It's not really a big deal though. The main issue is that you will have
to deal with data fragmentation, which means you must be able to
cumulate the full message before being able to decode it (remember that
TCP does not guarantee that you will receive your message in one single
fragment).
The best is to slightly modify your message, adding some data about the
full message size :
size / "BROADCAST" / serialized object
Or, if your text message is just a know verb, something like :
"BROADCAST" / object size / serialized object
Using a cumulative decoder, you'll be able to know when to stop grabbing
bytes and start the deserialization of the serialized object, because
you now its size.
I suggest you follow the sample provided in
http://mina.apache.org/chapter-11-codec-filter.html if you want to
implement such a decoder.
Hope it helps.
