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
