Rather maintaining global lists have you looked into using queries against the working memory to get out what you need? Thomas From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Fnu Mahalakshmi Sent: 18 June 2010 14:58 To: 'rules-users(a)lists.jboss.org' Subject: [rules-users] creating and integrating a specific output using drools Hi, I have my basic drools application up and running. Now I have a very disconnected input file (i.e all data is very diff from each other) As of now I am loading all the output data in a globallist and writing it to an output file. Now all the global lists are separate for different data inputs that I provide. Is there a more efficient way to do this rather than maintaining many global lists ??? Thank you.
