Environment:

Resolution:
========
Usually this exception is seen when you try to deploy a decision table based on a DB concept.

To resolve this issue, modify &ltBE home>\DecisionManager\configuration\bui-config.tra

1). Add the following property

bui.tester.engine.feature.level=local

It also works with 'full' but is not recommendation  unless it is required or you may inadvertently join someone else's tangosol cluster, plus it's harder to set up.

2). Add cep-modules.jar in tibco.bui.codegen.prepend_classpath, like following:

tibco.bui.codegen.prepend_classpath=C:/tibco/be/3.0/hotfix/lib/cep-common.jar;C:/tibco/be/3.0/hotfix/lib/be-functions.jar;C:/tibco/be/3.0/hotfix/lib/cep-kernel.jar;C:/tibco/be/3.0/lib/cep-common.jar;C:/tibco/be/3.0/lib/be-functions.jar;C:/tibco/be/3.0/lib/cep-kernel.jar;C:/tibco/be/3.0/lib/cep-modules.jar
