This is exactly what I want.

So, which kind of connection is established between the remote client and
eclipse TPTP ?

I'm getting confused here... reminds me of the early days of X11 when
"client" and "server" often seemed turned on their heads. The problem is
that I think most TPTP terminology turns on the client being the local
side of things (it's often the Eclipse workbench, but doesn't have to
be) and the "agent" being the remote thing that receives commands from
the client and returns data to the client (with either side of things,
sending commands or receiving data, being optional behavior).
So let me see if I can be clear on terminology while drawing you a
verbal picture, and then you can tell me how to translate betweeen our
On some local machine, as I said, you have a client. This wants to have
work done and receive data as a result. This side communicates to the
agent controller (AC, running on a remote system potentially, though it
also can run locally) through a normal socket (to port 10006 by default
for the "new technology AC"), which acts on its behalf. The AC can
launch processes (console processes, agents, etc.), and provides the
communication channel between the two (client and agent). The
communication channel is actually (potentially) many channels... a
command channel for issuing commands, and one or more data channels for
data communication between the two. E.g., for a "normal" (console)
process, you need three data channels... for stdin, stdout, and stderr.
The connection between AC and Agent is "wrapped up" in the API... you
really don't have to (and probably don't want to) know the details of
(Note that whether these command and data channels are each physically
separate or physically the same but logically separate is just an
implementation issue, and potentially a configurable one.)
It sounds like you're looking at things more from the agents
perspective... if so, then try looking at it from this perspective... if
you have some kind of process that receives commands (in some form) and
generates data, you'll want to modify that process to become an agent in
the following way:
(1) when the process starts up, registerAgent with the AC to let it know
you exist, can accept connections, and do your work on some clients behalf,
(2) implement a processCommand that "receives commands" indirectly from
the client through the AC instead of directly from the client, ... more
or less just a "packaging" of your command handling, and
(3) implement sendData that provides the resulting information back to
I'm assuming in all this you're willing to use the new technology AC
framework, that your agent will extend an agent framework (like
BaseCollector), and thus you get a lot of the necessary scaffolding that
lets it be as simple as the 1..2..3.. above. Your agent will inherit a
multithreaded approach with at least the processCommands getting invoked
from one thread, and hopefully you driving the sendData from another,
with perhaps a third thread sitting in waitForTermination.
That's sort of the verbal picture... you can get a little bit of
concreteness around this by downloading the "new technology Agent
Controller SDK" and looking at the Samples included in it...
specifically ConsoleTestClient, SimpleAppl, SampleClient, and
TimeCollector. They might clear up any confusion the above creates in
I also might recommend you look at the PerfmonAgent in the Samples... it
used to be an agent with the old AC (called the "RAC"... actually, it
still is an agent in its original form with the RAC distribution), and
it was modified to behave in just the 1..2..3.. form I describe above.
