[rules-users] Deploying Drools 5.0 project as Axis2 Web Service on Tomcat5.5

Hello, I want to deploy a Drools project as a web service. I am using Drools 5.0, tomcat-5.5.28 and Netbeans 6.9 to deploy the project as an Axis2 web service. The project just uses a simple decision table and works locally. If I try to run the service on the tomcat server I get the Runtime Exception java.lang.ClassNotFoundException: org.drools.rule.builder.dialect.clips.ClipsDialectConfiguration. I added all Drools libraries to the .aar file. Especially the drools-clips-5.0.1.jar is deployed, that should contain the missing class. I also tried to use the JANINO compiler as described here: http://community.jboss.org/wiki/RulesTomcat/diff?secondVersionNumber=8, but that didn't solve the problem. Are there any known conflicts between drools libraries and tomcat libraries that could cause the error? Thanks and Regards Hans Dampf The code that causes the error: public BREService(){ KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); final DecisionTableConfiguration dtableconfiguration = KnowledgeBuilderFactory.newDecisionTableConfiguration(); dtableconfiguration.setInputType( DecisionTableInputType.XLS ); kbuilder.add( ResourceFactory.newClassPathResource("Sample.xls", Laborwert.class ), ResourceType.DTABLE, dtableconfiguration); kbase = KnowledgeBaseFactory.newKnowledgeBase(); kbase.addKnowledgePackages(kbuilder.getKnowledgePackages()); } Error Message: [ERROR] Exception occurred while trying to invoke service method null org.apache.axis2.AxisFault: Unable to load dialect
