Senthil Kumar Kamaraj created DROOLS-2348: --------------------------------------------- Summary: KIE Workbench deployment on Tomcat fails when already droolsEngine jars are in tomcat/lib folder Key: DROOLS-2348 URL: https://issues.jboss.org/browse/DROOLS-2348 Project: Drools Issue Type: Bug Components: integration Affects Versions: 7.6.0.Final Reporter: Senthil Kumar Kamaraj Assignee: Mario Fusco Hi, We have deployed the drools engine and KIE workbench on Tomcat container. droolsEngine - All the jars from "drools-distribution-7.6.0.Final" are copied into the <tomcat_home>/lib folder KIE Workbench - kie-drools-wb-7.6.0.Final-tomcat8.war deployment on <tomcat_home>/webapps folder. Now the issue is, we are getting the below error, so that KIE Workbench is not deploying on tomcat. Caused by: java.lang.ClassCastException: org.drools.beliefs.bayes.assembler.BayesAssemblerService cannot be cast to org.kie.api.internal.assembler.KieAssemblerService If we exculde drools-beliefs-7.6.0.Final.jar jar from <tomcat_home>/lib folder then the KIE workbench is deployed successfully. But, both the deployments of drools 7.4.1 is succeeded without excluding drools-beliefs-7.4.1.Final.jar. Can any one help me in this issue.. Is there any restriction to deploy both on a single container (tomcat). Thanks Senthil -- This message was sent by Atlassian JIRA (v7.5.0#75005)
