Hi, I am using Drools 4.0.7 and was able to successfully create a knowledgebase. I am trying to install the knowledgebase in tomcat/axis2. I am running into problems here. The exception is below: org.drools.RuntimeDroolsException: Unable to load dialect 'org.drools.rule.build er.dialect.mvel.MVELDialectConfiguration:mvel' at org.drools.compiler.PackageBuilderConfiguration.addDialect(PackageBui lderConfiguration.java:160) at org.drools.compiler.PackageBuilderConfiguration.buildDialectConfigura tionMap(PackageBuilderConfiguration.java:146) at org.drools.compiler.PackageBuilderConfiguration.init(PackageBuilderCo nfiguration.java:121) The files in the lib directory in the aar file are below: C:\Users\rsundaar\projects\temp\SimpleService>jar tvf SimpleService.aar 0 Sat Apr 25 21:23:36 EDT 2009 META-INF/ 71 Sat Apr 25 21:23:36 EDT 2009 META-INF/MANIFEST.MF 0 Sat Apr 25 07:14:54 EDT 2009 com/ 0 Sat Apr 25 07:14:54 EDT 2009 com/satsoc/ 0 Sat Apr 25 08:20:12 EDT 2009 com/satsoc/prototype/ 1216 Sat Apr 25 07:54:36 EDT 2009 com/satsoc/prototype/Message.class 2293 Sat Apr 25 21:22:14 EDT 2009 com/satsoc/prototype/SimpleService.class 0 Thu Apr 23 06:34:56 EDT 2009 conf/ 0 Sat Apr 25 20:29:14 EDT 2009 lib/ 92015 Sat Mar 21 17:06:18 EDT 2009 lib/antlr-runtime.jar 109131 Fri Mar 20 23:56:50 EDT 2009 lib/drools-analytics-4.0.7.jar 10618 Fri Mar 20 23:56:50 EDT 2009 lib/drools-ant-4.0.7.jar 560267 Fri Mar 20 23:56:50 EDT 2009 lib/drools-compiler-4.0.7.jar 1096031 Fri Mar 20 23:56:48 EDT 2009 lib/drools-core-4.0.7.jar 78626 Fri Mar 20 23:56:48 EDT 2009 lib/drools-decisiontables-4.0.7.jar 23499 Fri Mar 20 23:56:48 EDT 2009 lib/drools-jsr94-4.0.7.jar 13749 Sat Mar 21 17:06:18 EDT 2009 lib/jsr94.jar 121070 Sat Mar 21 17:06:18 EDT 2009 lib/junit.jar 499068 Sat Mar 21 17:06:18 EDT 2009 lib/jxl.jar 870188 Sat Mar 21 17:06:18 EDT 2009 lib/mvel.jar 12745047 Sat Mar 21 16:55:50 EDT 2009 lib/org.drools.eclipse_4.0.7.jar 4372548 Sat Mar 21 15:35:48 EDT 2009 lib/org.eclipse.jdt.core_3.4.4.v_894_R34x.j ar 895924 Sat Mar 21 17:06:18 EDT 2009 lib/xercesImpl.jar 109318 Sat Mar 21 17:06:18 EDT 2009 lib/xml-apis.jar 119888 Sat Mar 21 17:06:18 EDT 2009 lib/xpp3.jar 24677 Sat Mar 21 21:53:52 EDT 2009 lib/xpp3_min.jar I have looked through some of the earlier postings. Based on that I have made sure, mvel.jar and org.eclipse.jdt.core_3.4.4.v_894_R34x.jar are in the lib directory and still get the same error. Any clues? I would appreciate any help I can get from you!! Thanks, Ravi. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
