I tried the following code and it worked. import java.util.ArrayList; rule createValidationReport dialect 'java' when ClaimRegistration($ailmentList : ailmentListFromScreen) then for(String ailment : (ArrayList<String>) $ailmentList){ System.out.println("ailment "+ailment); } System.out.println("then"); end But my requirement is to iterate the list in the when block and process something based on the data in the list. It should be something like import java.util.ArrayList; rule createValidationReport dialect 'java' when ClaimRegistration($ailmentList : ailmentListFromScreen) for(String ailment : (ArrayList<String>) $ailmentList){ System.out.println("ailment "+ailment); // My condition needs to be evaluated here } then System.out.println("then"); end Need help on this issue. Is this possible in Drools? kindly advice. Regards, Dinesh -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/How-to-Iterate-list-i...
