Hi, what I have is SOAP Web Service with two methods: fn_AddFacts, and fn_Conclude. I defined special XML implementation to send various fact's types via SOAP. Model is defined in DRL/Guvnor - and rules too. So now, I can add some facts (web service creates them using Drools "reflection" API) to knowledge base. And then use fn_Conclude method, to fire "fireAllRules" method and get response with results. But..... What if now I have 100 users, and I don't want their's facts to interfere each other? I want, to use Drools to conclude for different users. I want to use this same rules, but on different knowledge bases (each user has own knowledge base of his facts). Please help me, how to solve this problem... I am new in JAVA EE, and I don't understand some elementary issues well. (But I am trying to understand them :D ) regards, tom. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Thanks Esteban. I thought it could be a solution too, but I am not experienced (and my knowledge is not big either) in solving such a problems. If I would do, like You said - am I to write all communication between web service and client too? In web programming with browser, I have cookies. In them, I could keep some session ID. But using SOAP, I have to write this mechanisms alone, yes? Can AXIS do it for me? Or some other tool? regards, tom. 2010/8/20 Esteban Aliverti <esteban.aliverti(a)gmail.com&gt; A basic solution could be to have each user identified with an unique id. > Then, in the server side you could have different ksessions (and not kbases) > for each user. > > Best, > > XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX > > Esteban Aliverti > - Developer @ http://www.plugtree.com > - Blog @ http://ilesteban.wordpress.com > > > 2010/8/20 tom ska <tiberium.linux(a)gmail.com&gt; > >> Hi, >> what I have is SOAP Web Service with two methods: fn_AddFacts, and >> fn_Conclude.

Well, I will explain my architecture as well as I can: - I created "Dynamic Web Project" with Eclipse based on AXIS1.4.1 - I also added Drools Runtime to a project - In class I have KnowledgeBase kbase attribute - Each time I use fn_Conclude function, I create new StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession() and use fireAllRules method. I understand, that user who uses fn_Conclude will get his own results, but I don't get how using StatefulKnowledgeSession can I guarantee that user, who added his facts will get results only from facts he added. I see problem in connecting facts to user,but meybe that's not good point of view. Facts adding is done by ksession object (each user has his own), but I want to have this web service with states... Then user can add his own facts, than do something else, then process only his facts. Between adding and processing, I want other user to do this same. I want Web Service to wait for each user after adding by him some facts. I hope, it is clear for You (my english... :/ ) regards, tom. 2010/8/20 Mauricio Salatino <salaboy(a)gmail.com&gt; It depends on how are you exposing web services or the component behind > those web services.. > If you use a Stateful Session Bean, this component will do all the work > for you.
