Packaging of event mappers and JAXB serialization | HCL Digital Experience

It is good practice to package event mappers in a shared library rather than together with the business portlets.

If you decide to package event mappers with more than one business portlets, the Screen Flow Manager runs JAXB-based marshalling and unmarshaling. This action prevents ClassCastExceptions caused by the use of one or more isolated classloaders. You can influence the behavior of the JAXB based marshalling by using specific configuration options.
