Hi!
I'm having some trouble getting Neo4j DB to work from servlets in my Jetty
server.
There's no problem when I open the DB from a simple jar program file,
however when
I put the same code inside a servlet I get this exception:
org.neo4j.graphdb.TransactionFailureException: Could not create data source
[nioneodb], see nested exception for cause of error

I have to say that I'm not an expert at all dealing with jetty so it's
possible that this exception
is related to server configuration stuff I don't know about.
Any ideas?
Thanks in advance,
Cheers
