Answer 1

If you don't want to go the write your own JNI/C route.

The other option is to use jpype which for me is always what I use to access Oracle databases becuase installing the oracle c drivers on a PC is a pita. You can do stuff like (from docs):

 from jpype import * 
 startJVM("d:/tools/j2sdk/jre/bin/client/jvm.dll", "-ea") # or path to your jvm
 java.lang.System.out.println("hello world") 
 shutdownJVM()

It hasn't been updated in a while and there isn't much in the way of documentation but it does work reasonably well.
