[jboss-jira] [JBoss JIRA] Closed: (JBRULES-1230) Not able to run drools if core-3.2.3.v_686_R32x.jar is not specified in the classpath

Not able to run drools if core-3.2.3.v_686_R32x.jar is not specified in the classpath ------------------------------------------------------------------------------------- Key: JBRULES-1230 URL: https://jira.jboss.org/jira/browse/JBRULES-1230 Project: JBoss Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: All Affects Versions: 4.0.0.GA Environment: Windows XP, Dell Optiplex GX 270 Reporter: Krishnan Sivaramakrishna Iyer Assignee: Mark Proctor Priority: Minor 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. TIA, Krishnan. Comments from Edson Tirelli Krishnan, You should not need decision tables and jsr94 jars if you are not using such feature. Regarding the compiler, you must use either core (jdt) jar or Janino jar... I'm not aware of any hard dependency on core itself... if it exists, please open a jira for us to fix. []s Edson
