I'm working with JPA for the first time, and have come across a problem I can't seem to find a solution for, executing a WHERE IN native query.
The RegistrantsFilter isn't being used currently, I can't even run a test case. The Exception thrown isn't much help, just an EJB exception subsequently being thrown by an AbortProcessException.
I'm using EclipseLink JPA 2.0 to a MySQL 5.x database w/ Glassfish 3.1. My persistence.xml works with 4 other entity classes with basic CRUD operations, but this WHERE IN is starting to be the death of me. I've tried different data structures, removing the () around :branches, tried making the List generic with integers, everything.
