Dobromir,

I think that the best way to construct rule2 would
be:

<rule name="rule2">
   <param type="String">s</param>
     <when>
       <cond>( ! s.equalsIgnoreCase("dobromir") )</cond>
     </when>
     <then>
        pr.println("Don't know what to say!");
        retractObject( s );
     </then>
</rule> 

The idea is to contruct conditions that the engine can
see are the same or nearly the same to create a RETE network
that evaluates terms of conditions the minimum number of times.

I am not sure the the DROOL engine is up to the task.
