Here's what I would Do:
Create two LXRT tasks, making one of them hard-realtime, the other is
soft-realtime, both communicate using RTAI IPC calls. Additionally, the
second task opens a socket (say, a named pipe) and passes on the data on to
the socket.
You then write a java app that, too, opens the named pipe, and you use that
pipe to pass data from/to the LXRT app.
Of course the pipe may run full (the soft-realtime task will have to drop
data) whenn the java app is busy doing garbage collecting, but what did you
expect? :-)
