re[rules-users] move hardcoded values in DRL or have constants inside drl

[karthizap]

Thanks for your reply Earnie. In the following example, don't want to
hardcode Person Name value like "John" in the DRL file. I want to refer it
from some other sources(If i refer it from java class file, name value is
getting changed quiet often, have to recompile the java source and deploy).
My main requirement is, if the name value is getting changed, don't want to
redeploy/restart the application. i would like to do the changes in the drl
file only without hard coding.


rule "Test Rule"
	
	when
		$person : Person( name == "John") 
	then 
		$person.setActivation(true)
		
end

Karthikeyan

Please explain, how i can refer global object in LHS?
