Thanks again!
We seem to be making progress :P
With the logger off, i get the following exception:
Traceback (most recent call last):
File "neotest.py", line 9, in <module>
neo = NeoService("foo", classpath=["neo-1.0-b8.jar",
"jta-1_1.jar"], jvm="/usr/lib/jvm/java-6-openjdk/jre/lib/amd64/server/
libjvm.so")
File "/usr/lib/python2.5/site-packages/Neo4j.py-0.1_SNAPSHOT-
py2.5.egg/neo4j/__init__.py", line 459, in __new__
neo = core.load_neo(resource_uri, params)
File "/usr/lib/python2.5/site-packages/Neo4j.py-0.1_SNAPSHOT-
py2.5.egg/neo4j/_core.py", line 128, in load_neo
log.debug("Transaction joining in effect "
AttributeError: 'NoneType' object has no attribute 'debug'
with the logger on:
classpath is: ['neo-1.0-b8.jar', 'jta-1_1.jar']
ext_dirs is: ['/usr/lib/python2.5/site-packages/Neo4j.py-0.1_SNAPSHOT-
py2.5.egg/neo4j/classes']
Trying JCC backend.
Trying JPype backend.
Using JPype backend.
Transaction joining in effect (mechanism used to discover threads).
This isn't normal is it?
