[Pellet-users] Problem with running the RulesExample2 sample

[Evren Sirin]

Mostly for historic reasons Pellet rules support partly depended on 
OWLAPI structures on 1.5.0 release. You will need at least api-1.0.jar 
from lib/owlapi directory in Pellet distribution in the classpath for 
this example program to work. You might add all the jar files in that 
directory if you get more ClassNotFound exceptions. I think there is no 
OWLAPI dependency left in the rules support so this should not be an 
issue for the upcoming Pellet releases.

Cheers,
Evren
