java.util.MissingResourceException: system is missing product derivations
-------------------------------------------------------------------------

                 Key: OPENJPA-8
                 URL: http://issues.apache.org/jira/browse/OPENJPA-8
             Project: OpenJPA
          Issue Type: Bug
         Environment: Windows 2000, using ant build.
            Reporter: Neil Hornbeck
            Priority: Blocker


I am trying to run the openjpac from within ant.  I am getting the error that the file META-INF/services/org.apache.openjpa.conf.ProductDerivation
is missing but it is right on the classpath that the Enhancer is running from.

 [openjpac] Caused by: java.util.MissingResourceException: Your system is missing product
derivations.  Product derivations provide configuration options for supported da
ta stores and specifications.  You must have a META-INF/services/org.apache.openjpa.conf.ProductDerivation
file in your classpath listing the available derivation classes
, and some listed class must be instantiable.  Typically this file is bundled as part of the
distribution.  Have you unbundled it, or unbundled its listed classes?
