Subject Misleading error message
Date Thu, 23 Aug 2007 22:44:20 GMT
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");
