This is not Jess specific question. JVM simply can not find Java class

As for overall design, is C++ requirement? Can you do it all in Java?

Yasir,
Jess does not interpret string as arguments for the set method. You need
to specify each argument, like in:
(call ?futureCal set (Calendar.HOUR) 8)
where (Calendar.HOUR) is the jess call into static field.

That is because shadow fact uses getters from the object to populate
