Tom, just tried this, works for me (notice there is no #!/usr/bin/env python at the beginning of the file). If this and the last trivial snippet I sent does not work, I would suspect some hickups in the setup and installation of JPype and the Neo4j bindings?
I did (on Mac OS X, Python 2.6) 1. download http://sourceforge.net/projects/jpype/files/ 2. unzip and run "python setup.py build && python setup.py install" 3. svn export https://svn.neo4j.org/components/neo4j.py/trunk neo4j-python 4. cd neo4j-python && sudo python setup.py install 5. run the above script with "python test.py" Cheers, /peter neubauer COO and Sales, Neo Technology GTalk: neubauer.peter Skype peter.neubauer Phone +46 704 106975 LinkedIn http://www.linkedin.com/in/neubauer Twitter http://twitter.com/peterneubauer http://www.neo4j.org - Your high performance graph database. http://www.thoughtmade.com - Scandinavia's coolest Bring-a-Thing party.
