Hi
The import works fine but when I try to create the DB it falls over with the
following error.
>>> neo = NeoService( "/home/sky/Desktop/tmp" )
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/usr/local/lib/python2.6/dist-packages/Neo4j.py-0.1_SNAPSHOT-py2.6.egg/neo4j/__init__.py",

ImportError: No applicable backend found.
Looking through the archives I found this post
http://www.mail-archive.com/[email protected]/msg01589.html. Which
requested a more detailed error log, included below.

I have tried reinstalling both JCC and JPype, and both seem to be working
Would appreciate any help. Thanks
