When I use nginx as a proxy and block the access to the port 7474, It seems
that the connection is lost when I'm on the web application...
If I understand, the instance of the neo4j ui server is running on jetty?
Why is not possible to configure jetty like we want?
thanks

Hi John,
Thanks for showing an interest.
The compile error you got was due to the fact that a removed class was still
hanging around in the Git repo. I renamed BinaryRelationshipRoles into
BinaryRelationshipRole, but the original file was still active in the Git repo.
I fixed that.

I've this strange problem when I try to collect data from the graph with
the Java API in Groovy :

When iterating over all nodes, you also pull the reference node (with id = 0),
which probably doesn't have the requested property.
If you want to list all properties of a node, it's better to use a construct
like:
for(String key: node.getPropertyKeys()){

I think the hard part about transactions is recovering after crashes and

Regarding finding A--B, have you tried using a relationship index? See:

Hi Aseem,
When you GET a resource, you're asking for its state at a particular instant in
time. GET's don't always return the same content, what's important about them
is that clients can't be held responsible for any (unintended) side-effects of
a GET operation. For example, if you GET the

Feature (though perhaps PUT) would be a better choice of method. POSTing a new
set of properties can't update, because the semantics aren't clear - what would
it mean if a property was missing, is that an effective DELETE, or an
indication it should be left alone.

I checked the Git repo, and left two more files in that I had removed in my
local project. (Note to self: When deleting or renaming files always update

Actually the Enhanced API doesn't use any index at this moment. All look ups
are done within the graph and are all either ID lookups or a traversal of no
more than three relationships.
Including DBD would only serve to remove this book keeping from the graph. For

another page (via the main Google search page) is a JSON packet...which
I'd like to take a stab at implementing traversals in the Enhanced API. One of
