implement autoresume file sending in activemq?
what can I do to implement this ? I think I can maintain the connection
and destination in client, and get the outputstream if resume is acted.But I
do not have a try,I do not know how dose the server handle stream msg ,so
I can't predict the actually behavior of the server. any suggestion?
especially whether there exists some API that I can judge a new msg or a
resume msg from the server?

If you are using auto-reconnection, then I don't think you should need
to do anything particular to re-resume things on a reconnection. So
just use the failover: transport to connect to the broker and use JMS
streams

I have met another probelm: if I interrupt the server while sending file, no
affection on sender.but when I try to receive the file, I encounted an
exception, it says
java.io.IOException: Received an unexpected message: expected ID: 264 but
was: 265 for message.
thanks for suggestion.

Its your call - if you want, failover can keep trying to reconnect for
a period of time then throw an exception and fail - or you can keep
auto-reconnecting for ever if you prefer.

Currently we have no solution to automatically re-start the client if
it fails midway through.

yes! I just have a try,it is. thanks.
but if I just keep a connection and dose nothing ,shut down server will shut
down the client with no exception. this is the test I have done before. so
I thought you was misunderstanding me. sorry!
but how could I do if the client is shut down? no way or do it myself using
other technology?
thanks to any suggestion.

The failover: transport does that part for you.

thanks for reply.
but I think there is a misunderstanding. my problem is the server is shut
down while a client is sending a file using stream message, how could the
client resume the sending? the definition of 'resume' here is just send the
remained content of the file when the server is up again.
thanks again!
