http://drools.46999.n3.nabble.com/file/n3979822/Sans_titre.jpg I have this decision table. I have a Class XMLTool which contains static fields as SICF and some methods (non static) as addNodes(String str); I don't find the way to use the method addNodes in my decision table. (I import all the good classes) I tried several stuff but no success. I'm sure there is one good way to do it.

Sorry, I read too fast ... You have addNode(...) on XMLTool ? So you have to get a XMLTool somewhere in CONDITION or make it a global variable, or a java singleton, or link it with your service. If you can't do all previous, then you will have to find a trick to match it in your conditions, but it will be a trick ... ----- Mail original ----- De: "Vincent LEGENDRE" <vincent.legendre(a)eurodecision.com&gt; À: "Rules Users List" <rules-users(a)lists.jboss.org&gt; Envoyé: Vendredi 11 Mai 2012 15:06:35 Objet: Re: [rules-users] Decision table call external method In ACTION, you can use : - static methods - non-static method on a previous matched objects using "addNode(...)" like this is nonsense, even in plain java If your addNode method applies to your matched Service object (which you binded to variable "s"), use "s.addNode(...)"

If there is just one object of class XMLTool and all addNode() calls should refer to this single object, you should do what Vincent suggested by making this single object accessible via a DRL global variable, or by using the singleton design pattern (as in Java). Adding this object as a fact and using (by applying tricks) it in the condition isn't the way this is supposed to be done (as you have rightly noticed). -W -- View this message in context: http://drools.46999.n3.nabble.com/Decision-table-call-external-method-tp3...
