Misleading error message
Hi,
Running the following code, and if the jpox.properties cannot be found, a
misleading message is raised that indicates a missing a EntityManager
persistence provider, but should actually tell me that my resource
jpox.properties cannot be found.
PersistenceManagerFactory pmf =
JDOHelper.getPersistenceManagerFactory("jpox.properties");
------------------
