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?
