JOGL is a pretty low-level API, almost direct calls to OpenGL wich is a quite hard API to use. Maybe you will have better progress using a games framework that usually have code for doing operations like displaying a height-field.
Personally I like jMonekyEngine (http://jmonkeyengine.org/) or Ardor3D (https://github.com/gouessej/Ardor3D).
Even if you do not use those libraries you can look at their source code to learn how they do for displaying a height field.
