[rules-users] error while running a dsl

[Michael Anstis]

Your DSL shows a class called "employee" with field "statename".

Perhaps your DSL should read:-

[when]employee belongs to a particular state{state}=$employee:employee
(state=="{state}");

[then]Greet Employee=System.out.println("Hello");

Your class name "employee" also doesn't follow normal practice of
capitalising the first letter; so "Employee" would be preferential.
