frnds i have a rule
 
and its not working and i  for checking i have put a Sop in my  when  but it not  prints  the 
Inside Area_SqFt_1_10-01-09_12-31-14
so how can we put SOP inside when clause.

rule "Area_SqFt_1_10-01-09_12-31-14"

date-effective "01-Oct-2009" date-expires "31-Dec-2014" salience 6

no-loop true

when

System.out.println("Inside Area_SqFt_1_10-01-09_12-31-14");

objectP2483 : Para_2483( (fid2335=="Block") && (fid2336==16) );

then

System.out.println("Area_SqFt_1_10-01-09_12-31-14");

objectP2483.setFid31003(new Double(497)); end
