      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 

      <server>
<!-- ==================================================================== -->
 <!-- Invokers to the JMX node -->
 <!-- ==================================================================== -->
 <mbean code="org.jboss.remoting.transport.Connector"
