hi all, In my application, I use simple drl file based rules and it is not a J2EE application. Based on the dependencies documentation http://anonsvn.labs.jboss.com/labs/jbossrules/tags/4.0.1.14754GA/README_D... , it seems I am in the compiler option The only jars I am including are as follows :- drools-compiler-4.0.0.jar drools-core-4.0.0.jar drools-decisiontables-4.0.0.jar drools-jsr94-4.0.0.jar antlr-runtime-3.0.jar mvel14-1.2rc1.jar core-3.2.3.v_686_R32x.jar [Can anyone explain why I need this, the documentation seems like this is optional, but when I don't specify this, it does not work ?.] I also tried not including the core but including the janino library and specifying the janino compiler at run time and that also expects the core to be included. Any help is appreciated.
