Project: Cayenne
Issue Type: Bug
Components: Cayenne JPA
Affects Versions: 3.0M5
Environment: MS Windows XP
Eclipse 3.4.1
JDK 1.5.08
Reporter: Neil Rutherford
Attachments: patch.diff
While running a test app with 1 entity from inside Eclipse I get the below
exception:
2009/03/12 02:17:03 org.apache.cayenne.jpa.Provider createEntityManagerFactory
INFO: Extra PersistenceUnitInfo properties: {}
Exception in thread "main" java.lang.NoClassDefFoundError:

This seems to be caused by this line in
org.apache.cayenne.jpa.conf.EntityMapLoader (inside
locateClassesInFolder(File,...):
classes.add(absPath.substring(
rootPathLength,
absPath.length() - suffixLen).replace('/',
'.'));
because on Windows the path separator is a '\\', replacing the '/' with
File.separatorChar fixes my problem.
