Hi, For using queries against the working memory : we do again need a knowledge of which query to fire against the working memory depending on which rule is fired. Also maintain a list of different queries which is ultimately written out to our output file. Is there any way to determine this in our rule itself?? I could set a variable stating which query to be fired. But again I will be maintaining a lot of global variables then. Any idea?? Any better solution??? Thanks M ---------------------------------------------------------------------- Message: 2 Date: Fri, 18 Jun 2010 15:12:28 +0100 From: "Swindells, Thomas" <TSwindells(a)nds.com&gt; Subject: Re: [rules-users] creating and integrating a specific output using drools To: Rules Users List <rules-users(a)lists.jboss.org&gt; Message-ID: <DAC86F5F3B84F14088F0DB16092558CA090238F5E7(a)UKMA1.UK.NDS.COM&gt; Content-Type: text/plain; charset="us-ascii" Rather maintaining global lists have you looked into using queries against the working memory to get out what you need?
