Re: [Java-player-users] Questions about where to start upgrading JavaClient

[Leo N. <leo...@gm...>]

I have never found any documentation regarding the communication. Indeed,
the xdr library is build "on the fly" depending on the contents of the
"playercore/player.h" header by a Python process
"playerxdr/playerxdrgen.py".
The reason I have not released any patched version of the JavaClient is that
a patch will only work for a few time, as P/S developers do not consider
changes in this communication a problem, what unfortunately is a big issue
for those trying to interface Player from other languages. What we are
developing now is a process similar to this playerxdrgen to create the
xdr-based communications on java on-the-fly.

Hope this helps
