public class VMJavaActivity
extends JavaActivity

A VMJavaActivity is a java activity with extensions for use in the virtual machine. A java activity is a primitive activity but is used to call an externally specified activity written in Java. The external java activity is specified in a class that either implements the IExternalActivity interface or extends the AbstractExternalActivity class.
