Trying to integrate either Java or a C++ library into PHP just so that one can
run a Java or C++ machine learning system sounds really painful. Unless the
performance needs to be high and the transaction latency extremely low, this
sounds like a perfect case for NOT integrating the code, but calling it via
some sort of remote procedure call (RPC) or remote method instantiation (RMI
-- Javaspeak for a previously existing concept -- grrrr >:-( ).
How about writing a Java server that does the machine language stuff that can
accept an XML-RPC socket connection from Drupal instead? That's got to be a
thousand times easier to do, and the performance won't be that bad.
I've already done this kind of thing twice. In one instance I open a socket
to a Java server to do "real time" transactions with it from a Drupal module,
and in another, I make a SOAP connection to a C++ server from a Drupal module,
likewise to do "real time" transactions. I would not even have a prototype
working if I tried to write a PHP extension that tried to run the Java or C++
