SOAP has been mentioned, but I would also look at REST. An http post 
with an XML response although less powerful, has a wider range of 
support. Using port 80/443 to get to a server also greatly simplifies 
firewall issues when the systems are remote.

The biggest drawback to JNI (I feel) is that it opens up all the 
disadvantages of C in a Java environment. It is difficult (for me) at 
times to determine exactly where an error actually is as I use C only 
when forced to.

That is given by the HTTP transport more than the RPC style SOAP
vs RESTful POX.
