How to make a "Custom VI" in Java?

[Zaque]

Hello all,

In the past, our team has used LABView to program our robots. This year, we have switched over to Java. In LV, I could make custom vi's to do, for example, ramping. I have a small understanding of the concepts needed to do this in java, but it is very, very hazy, so if anyone could point me to a tutorial or other documentation on how to do this, I would much appreciate it.

Thanks,
Zaque
