error parsing repository.xml

Fri, 09 Jan 2004 20:37:35 -0800

I've got a very strange error cropping up when I try to run a simple test program for OJB.  Note that I can build and execute the JUnit tests using the distribution and things work fine.  However, when I construct a simple batch file to include all the jar files from the ojb "lib" directory and add in the directory that contains the properties files I get a NullPointer exception during the parse due to "isolation-level" being null.  Now this appears to be an internal table lookup, so I'm not sure how it can fail.  Also, I copied the repository.xml file from the OJB distribution as my starting point, so the isolation-level attribute is being properly specified.  I've attached the debug output and the exception trace below. Any help or insights would be appreciated.

Thanks.
