- Closing the socket connection and sending multiple res 2007-07-18 - By cazuza

Please I need help,
Appologies in advance if the questions are too naive, but I'm just starting
with Jboss and have a head full of doubts.
I have try to implement a socket server using jboss remoting and have hit a
wall.
the timeout attribute works but doesn't close the socket instead it sends error
messages to the console.

unless the client closes the connection itself it seems that the server will
timeout and write error messages to STDERR. I don't want to rely on the client
to close the connection, is it possible to close the socket connection after
sending the response?
the other question is How do I send multiple messages back to the client. At
the moment on my invoke method I receive the request, parse it and return a
string, what do I have to do to send another string without concatenating to
the previous string? lets say I'm reading a huge file and want to send it line
by line.
here is my configuration file
