Dear all, I initially did my project in WebLogic using the following jars: *drools-compiler-4.0.7.jar *drools-core-4.0.7.jar *drools-decisiontables-4.0.7.jar *drools-repository-4.0.7.jar However, now I need to port all of these to a JBoss server. On doing so, I got some exceptions on "Eclipse" ??? Knowing more I realised that this is some compiler conflict. The sites I hit upon are- http://www.mail-archive.com/rules-users@lists.jboss.org/msg00375.html http://www.jboss.org/community/docs/DOC-11925 What is JBoss-rules and how different is it from a the compiler that I'm using listed above? Are there any 'other' jars to be used specifically for JBoss?? Thanks a lot. -Promod George
