NetworkTable error

[Arhowk]

I'm trying to make a SmartDashboard application that communicates with the robot via network tables. Im trying to use this code


NetworkTable.setIPAddress("10.20.12.2");
NetworkTable.setClientMode();
try {
NetworkTable.initialize();
} catch (Exception e) {
e.printStackTrace();
}
t = NetworkTable

but it prints this error

It looks like it's using the cRIO version of network tables. If you're writing a program for your computer, you need to use the networktables-desktop.jar.

would you mind posting a link to that jar file? :D

[fovea1959]

hunt around in your sunspotfrc folder; I'm pretty sure it's gets plopped there as part of the Netbeans FRC Plugin install.

[fovea1959]

yep. in the desktop-lib subfolder of the sunspotfrcsdk folder.
