I'm new to the ICN environment, so I'm sorry if these are easy questions to answer.
I'm trying to extend functionality on the default properties section of the adding documents action. I'd like to query based on a field, then update the rest with the results. There should be no other changes, just that switching fields in the properties section will execute the query. If my understanding is correct (based on the ICN customization redbook), I'll need a plugin .jar file which calls the service, and the EDS service .war file which will handle the field updating.
Where should the query be run from? Is there anything that I'm missing? Am I wrong in thinking that the field updating should be defined in the .war file?
