Hey Tobias,
I finally got it working (reinstalled the neo4j.py library with a
fresh python2.5 install). What I'm having trouble with now is running
the sample application. I've tried several combos of this:
neo = NeoService("foo", classpath=["neo-1.0-b8.jar", "jta-1_1.jar"])
with neo.transaction:
ref_node = neo.reference_node
new_node = neo.node()
# put operations that manipulate the node space here ...
neo.shutdown()
I've also tried a version where I supplied the jvm path as /usr/lib/
jvm/java-6-openjdk/jre/lib/amd64/server/libjvm.so
However, every time I try to run it, i get:
Traceback (most recent call last):
File "neotest.py", line 4, in <module>
neo = NeoService("foo", classpath=["neo-1.0-b8.jar",
"jta-1_1.jar"])
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 56, in load_neo
backend.initialize(**parameters)
File "/usr/lib/python2.5/site-packages/Neo4j.py-0.1_SNAPSHOT-
py2.5.egg/neo4j/_backend/__init__.py", line 52, in initialize
raise ImportError("No applicable backend found.")
ImportError: No applicable backend found.
I've been trying to get help in #python on freenode for the past few
hours but to no avail. I'm fairly frustrated and decided to write a
jar and just access it from python's subprocess module, but if you
know what's wrong I would appreciate it. I'd love to get this working
with pure cpython and not try any hacks.
Thanks,
Karan
