Hi,

 

            I am using eclipse IDE for Drools.

 

            I am new to Drools so just trying adding to numbers if they are other then zero, but I am getting Null Pointer Exception .

 

 

rule add

            salience 10

            when

                        a1 : AddNumber ( op1 != 0 )

                        a2: AddNumber ( op2 != 0 )

 

            then

                        a1.setResult( a1.getOp1() + a2.getOp2() );

System.out.println( "Result is "+a1.getResult());

End

 

 

Regards

Shilpa
