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

You can't directly use java code inside the LHS of a rule. You can though
use eval to call a java method inside your LHS. Also remember that you don't
have to use ; in the patterns.

You should read at least chapter 4 of
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-expert/ht...
where eval() and everything else you can use in a rule is described.
Using output statements on the left hand side of a rule is not a very good
way of determining whether a rule fires or not. Using the
KnowledgeRuntimeLogger (see section 3.3.6) might be a better way of seeing
what goes on in your rule based system.
There is no special class for methods you can call in an eval(). An import
(in the .drl file) may be required if it is a static method. In any case, an
expression used inside eval() must result in a boolean value.
