However when deploy using the same solution on a WAS 8.5 cluster (3 WAS App server and 1 deploy manager), we can access the home page, but no link on the page works.We see exception and message "The CDI BeanManager is not available for applications that are not CDI enabled". Our web app does not use CDI. If we package a beans.xml, the exception becomes "java.lang.ClassCastException: org.apache.webbeans.context.CustomContextImpl incompatible with com.sun.faces.flow.FlowDiscoveryCDIContext". IBM analyzed the trace from our local WAS where the web application works fine, they see nowhere CDI is logged. But we could not get rid of CDI exceptions on WAS cluster after trying different configurations.
