I'm new to Neo4J and I want to work with it using Java.  I want to be able
to create/update/delete Nodes, Relationships programmatically and to
dynamically add/remove properties and relationships from nodes.

*Three questions*

   1. Is Spring Data Neo4J the way to go, or should I stick with the native
   Neo4J API?
   2. Is graph traversal via the traversal API recommended or is CYPHER
   replacing that API?
   3. Where can I get an up to date end-to-end Java tutorial? Seems like a
   lot of tutorials are outdated.

Depends, if you have an object domain model which you want to map to a graph or if a more procedural approach of doing the mapping would suit you better.
The core-api is better suited for really dynamic properties and relationships. in SDN you would use different domain types that you can project the nodes/rels to.

The tutorial in the manual is always up to date: http://docs.neo4j.org/chunked/milestone/tutorials-java-embedded.html (Or which tutorials did you mean with outdated?)

You can also stick to cypher which now has update functionality.

Usually we nowadays recommend cypher and see the Java API as a performance optimization.

Cheers

Michael

Thank you.

I'll use Spring Data Neo4J because I have a domain model.  I'm having a
hard time finding a complete example that can help me do the following:

   1. I'm running Neo4J as a Server instead of as an embedded server.
   2. I want to connect to the Neo4J server using Spring Data Neo4J and
   perform CRUD operations.  I've found out about SpringRestGraphDatabase but
   I can't find any example of how to configure/use it.

Is there a complete step-by-step tutorial available that shows full Java
code and configuration details for connecting to a Neo4J server using
Spring Data Neo4J SpringRestGraphDatabase?

Hi,

You can find the documentations for configuration in 21st chapter of 'Good
Relationships' doc, here is the link for the same,
http://static.springsource.org/spring-data/data-neo4j/docs/2.1.0.RELE...

Also, please find below the sample configuration,

<context:annotation-config />

<context:spring-configured />

     <!-- Neo4j configuration (creates Neo4jTemplate) -->

    <neo4j:config graphDatabaseService="graphDatabaseService"/>

    <!-- REST Connection to Neo4j server -->

    <bean class=
"org.springframework.data.neo4j.rest.SpringRestGraphDatabase" id=
"graphDatabaseService">

 <constructor-arg index="0" value="#{systemEnvironment['NEO4J_REST_URL']}"/>

 <constructor-arg index="1" value="#{systemEnvironment['NEO4J_LOGIN']}"/>

 <constructor-arg index="2" value="#{systemEnvironment['NEO4J_PASSWORD']}"/>

 <!--<constructor-arg index="0" value="http://localhost:7474/db/data" />-->

    </bean>

<!-- Package w/ automatic repositories -->

<neo4j:repositories base-package="org.netvogue.server.neo4japi.repository"
/>

 <context:component-scan base-package="org.netvogue.server.neo4japi"/>

 <context:property-placeholder location="classpath*:*.properties"/>

Thanks,
Abdul

What is the name of the file and it's location where this configuration
information should go?

Hi,

You can add this part of applicationcontext.xml file or you can have
separate configuration file specific to Neo4j like
neo4j-applicationcontext.xml file and load this.
