Yes the first try is this one.

Pierre will be glad to ear you :=)
The only trouble here is that the Java Federate has to launch a native
executable (RTIA). So Java Federate depends on a RTIA running on the
targeted platform.

We discuss the fact that we may implement RTIA in java too,
this way the Federate is 100% java and RTIA in java may be
java thread with potentially better performance than
(TCP) socket communication with the C++ RTIA.

The conclusion was that implementing RTIA in java is not
an easy task, so we started with a "simple" libRTI in java.

I say we "started" but may be it's already the best solution who knows...

Yep, I've already eared that :=)

I did not have time to give it a try, but I will and keep you informed.
