Gary,
(and other interested parties):
Here is a kludgy first pass:
https://github.com/SWATRobotics/JniBridgeTest1/
to test it out without a robot, run TableViewer in server mode on, say, the local host. Let's say that localhost's IP address is 1.2.3.4. Change the IP address in the code to "1.2.3.4". (and the PATH environment variable needs to be right, and this code assumes that networktables-desktop.jar is at C:\Windriver\WPILib\desktop-lib\) The JDK and/or the JRE needs to be installed already. I suspect that I have left some dangling references in, which may be why the destroyJVM call had to be commented out.
This is NOT a complete interface to NetworkTables; additional methods can be added. I'll try to post the method signatures for the whole NetworkTables as an additional commit later.
Please let me know if you have any questions.
Best,
Martin
