Hi Jojan, In 3.0.6 you can use Java zero-argument functions in LHS Return Value predicates and operators (see the documentation). You can use any Java in LHS eval statements (see the documentation). You can use any Java in the RHS. In 4.0.x this has been extended slightly to allow access to maps by named element, but I think it internally generates evals from your DRL. See the various links about what's new in v4.0.x for more (accurate) information. With kind regards, Mike -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Joj Sent: 31 May 2007 16:17 To: rules-users(a)lists.jboss.org Subject: [rules-users] Java methods in LHS ?
