Sorry for the quantity of my questions, and I apologize in advance if any of
them are trivial or stupid.
ok - so I guess that in my Session Bean I would use the regular old
@Resource annotation:
@Resource
GraphDatabaseService graphDb;
Or do I need to declare Neo to jndi and then reference it?
No, that's wrong. To create ( and shut down GraphDatabaseService in
your bean, you should:
1) create @Singleton session bean. In its @PostConstruct method,
create appropriate GraphDataBase service object, and stop it in
@PreDestroy method. You can mark that bean as created on startup, if
you wish
I have two projects. One is full-on J2EE using Glassfish. The other is
Servlet based, using Tomcat.
At this point I am not using Spring or Guice - the only injection I get is
the standard J2EE injection for my beans.

wouldn't want to clog up the mail list with the hand holding - especially if
I summarize it in a cookbook).

We can fork of the discussion to a thread at help.neo4j.org then it stays

I would love if you could do that.
Btw. I also meant plain J2EE injection not spring or guice.

My understanding of the J2EE standard is that you should *not* do file I/O
from inside a bean (my assumption is to avoid issues if you run in a
clustered environment). If I access Neo4j directly from a bean, wouldn't I
be violating that?
I am not currently clustered, and my app is small enough I
To answer a few of your questions:
Neo4j is a database, GraphDatabaseService encapsulates your connection to
that database.
You don't mind using other databases from J2EE. If you run clustered just use
Neo4j's High Availability mode across the cluster.
As Neo4j has no concept of a connection
I use neo4j in Glassfish, with JCA connector (
https://github.com/alexsmirnov/neo4j-connector ), and currently tested
it with Jboss7.
The connector has been created for my startup project (
www.netoprise.com, sorry for horrible design, ot's only 10% done ),
and I plan to convert it to HA connector
Hi,
do you mean a javax.sql.DataSource or an JCA adaptor ?
Could you please explain your architecture and usage scenario where this would
be necessary.
You can use Neo4j in embedded mode inside any J2EE container without issues. If
the container
comes with its own XA-TM then you can
