Re: problem with NChar in Oracle 10g

Hi Mohammad, I don't think we can set a system property by using persistence.xml and even if we could, that would affect your entire app server anyways. System properties affect the whole JVM even if set during runtime. The Oracle doc you mentioned [1] suggests that you can use

Re: Best way to prime OpenJPA before first request?

I'm building a REST-based app using CXF and OpenJPA 1.2.1. The app works fine, but I've noticed that the first request to the app after startup takes quite a while, and most of the time is spent on the first JPA request. Following requests, even for different objects and classes, goes much

Re: How to implement a map where the key is in the join table, not in the target table?

For JPA 2.0 (OpenJPA trunk), the map key does not need to be a field in the target entity. For example, please see the test case in org.apache.openjpa.persistence.jdbc.maps.*. - Original Message From: KARR, DAVID (ATTCINW) dk0...@att.com To: users@openjpa.apache.org Sent: Tue,
