If the thing that triggers them is written in Java, you still have to
fire up the JVM.  To get around that you could use Excelsion jet which
creates native executables that start quickly.

You generate C code for the triggers and compile it. It could send a
TCP-IP request to your server code.

See http://mindprod.com/products1.html#ECHOSERVER for an absolutely
bare bones server you might flesh out.
