[protege-owl] a question about SWRL inference

Hi,

I have two properties which are in inverse relationship, for instance:
hasFather(?a, ?b) <-> isFatherOf(?c, ?d)

I tried to use SWRL to  create rules to get the inferred triple assertions.
For examples, I have a triple:

hadFather(Jack, Paul)

and I created a rule such as:

 hasFather(?a, ?b) -> isFatherOf(?b, ?a)

 But by running Jess on this rule, I could not get the inferred triple:
isFatherOf(Paul, Jack)

What is wrong? or is it not doable?

Thanks for any tips!

yy.
