[rules-users] how to check reference

[Sikkandar Nawabjan]

Hi,
we are using drools version 3.0.6. I want to check the object references of t inserted objects in working memory.
How to check the condition in LHS?
right now am doing the following way
when 
    $obj1:object()
    $obj2:object()
then
   if($obj1!=$obj2)
         System.out.println("Fired");
 
how to move the if(if($obj1!=$obj2)) statement to LHS? am not able to use this operator in version 3.0.6
Thanks and Regs.
Basha
