[Pellet-users] Using Jess API and Pellet OWL-API, possible?

Thanks Bijan for your reply. However, at this moment I would like to concentrate back on Pellet. 
 
I was trying out with SWRL in my ontology and I needed the SWRL builtins (i.e. swrlb:add, swrlb:mutiply,swrlb:stringEqualIgnoreCase), however Pellet ignores those rules that have such builtins when I did a test using the Jena API. 
1) Could anyone please explain why are such builtins ignored? Are ALL builtins not classified as DL Safe SWRL rules?
2) Is there any possible solutions within the scope of Pellet other than using Jess to execute the rules?
 
Thanks for your attention.
