You can run the JT4Demo two different ways:
- On the same computer that runs the JavaTest harness (in a
separate JVM) by means of the Runtime.execJava API
method.
- On another computer or device using a JavaTest Agent.  The
JavaTest Agent runs tests on a separate computer and communicates
with the JavaTest harness over the network.  Choose this answer if
you cannot run your tests on the same computer that runs the JavaTest
harness.
