Except, unfortunately, that the project in question does not use Hibernate. It seems that there is no way to accomplish this through EJB: http://forum.java.sun.com/thread.jspa?threadID=5174100&messageID=9671593 The impetus for this post was that, with a sufficiently large number of entities, I experience transaction timeouts due to the length of time it takes to iterate over the entities and delete everything using EJB's remove(). That said, perhaps the best (in this case, fastest) way to do this would be to use JDBC to delete the records and then iterate over any entities hanging around in the EJB cache and call remove() on those.
