hi, you can't use stateless session for your problem. http://downloads.jboss.com/drools/docs/5.1.1.34858.FINAL/drools-expert/ht... "A stateless session can be called like a function passing it some data and then receiving some results back" the way i understand "...receiving some results back" part is that facts can be updated (you can call methods on them) but inserting any new facts into session in WHEN section is not possible On 06/05/2011 20:05, Dean Whisnant wrote: This is not an answer to your question, but rather asking the same question with a slight twist: I'm in the middle of trying to see if I can shift from stateful to stateless in my project and the "session.getObjects" method is what we would use in stateful as well to read back all of the new objects created during rules execution. My project seems to be much more geared towards stateless and thus far testing has shown our time would benefit significantly from the change. I see in the docs where ExecutionResults are used with the execute: ExecutionResults results = ksession.execute(CommandFactory.newBatchExecution( cmds) ); But even within results I do not see how to gather my objects from memory. Any thoughts on what I am missing here?

I have the following rule definition: rule "open work item" when Task ( status == "OPEN") then insert(new Action("Take","take_task")); insert(new Action("Complete","complete_task")); insert(new Action("Close","close_task")); end Basically I want to insert a Task and then get back a list of Actions that are available for the Task (based on the status. I have this working with a statefulknowledgesession with the code: List<Command> commands = new ArrayList<Command>(); for (Task task : tasks) { commands.add(CommandFactory.newInsert(task)); } session.execute(CommandFactory.newBatchExecution(commands)); session.fireAllRules(); session.dispose(); //this returns the actions Collection objects = session.getObjects(new ClassObjectFilter(Action.class)); I was wondering whether it is possible to do this with a statelessknowledgesession instead? I could'nt see how to achieve this without updating the task to include the actions. Any help would be appreciated.
