I am trying to consume an Object type message from an Oracle Transaction Event Queue from a java application and it is throwing the above error. A little googling reveals that a custom java class that implements ORADataFactory interface must be specified when creating the subscriber in a pub/sub pattern.
I do not have enough information regarding the concepts and/or mechanics of implementing such a class and wiring it up to the rest of my java consumer code. I couldn't find a clear description of the concepts and implementation guidelines in the TEQ documentation. I believe the same help is needed for JSON data type in TEQs consumed with JMS.
Thank you
