You have something similar to what you want. If *resultState *is a global variable, there is nothing stopping you from writing any amount of java code you want in the consequence part. Create whatever you want and then do *resultState.add(SOMEOBJECT); *You already perform a similar action with the code you have already: frontAxleAttributes.put("Capacity" ,new Double(c.attributes.Capacity)); hth Minh On 10/18/2010 2:58 PM, Navdeep Kumar wrote: Hi..

Please do check the global declaration if that is wrong.* will appreciate your help.

AvailabilityRuleState s = new AvailabilityRuleState(); s.setValue("Not Available"); s.setReason("Type Specific"); s.setReference("Availability rule FrontAxle and FrontSuspension Type"); resultState.add(s); this code is not working..can you please tell me what will be the syntax for creating a new Object in the rule consequence. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/How-can-i-create-a-ne...
