How are you invoking the java?  Are you loading a new instance every time?

My personal recommendation is to create a java server that's launched on 
system start up. The server code listens on a data queue.  Native code 
would then send a message to the server via the data queue and get it's 
response there.

That way you incur the java startup penalty once.
