Can openjpa scan directories for classes (such as WEB-INF/classes)?

[David Jencks]

I'm having some trouble getting openjpa to work properly with  
persistence units directly in unpacked wars in geronimo, and before I  
spend a lot of time looking for dead ends I wonder if anyone knows if  
there are some circumstances in which openjpa can scan for classes in  
an unpacked directory such as WEB-INF/classes?  Right now in the  
geronimo integration openjpa seems to be trying to read the directory  
as if it is an xml file, which fails with a SAX exception:

Caused by: java.io.IOException: org.xml.sax.SAXException: file:/Users/ 
david/geronimo/svn/(.....).war/WEB-INF/classes/ [Location: Line: 1,  
C: 1]: org.xml.sax.SAXParseException: Content is not allowed in prolog.
