Since version 1.2.7 the desktop enforce and implemented neo4j scheme to connect to Aura instance.
This needs to be reflected in https://neo4j.com/developer/aura-connect-neo4j-desktop/ instructions

In head_partial.erb the <title> HTML tag is hard-coded to be the same title for pretty much every page.

I'm unsure of the ruby templating bits of how to state a title in the asciidoc pages, but that variable needs to be set, and then I guess head_partial.erb needs to substitute it.

Will look further into this when I can get the time.

So it seems that getting Spring-boot and spring-data-neo4j 3.3.0 to talk to each other proves troublesome. I have tried doing several of the different examples for Spring boot and all work fine until I try and use spring-data-neo4j 3.3.0 or higher. I've been banging my head against this wall for a few days, does anyone have any advice for me on how to implement a simple rest interface using spring-data-neo4j-3.3.0? This is mostly for faster iterative development on eventual server extension methods. The error I continously get is:

java.lang.NoClassDefFoundError: org/springframework/data/mapping/PersistentPropertyAccessor

i followed the doc.. but when i do "mvn compile exec:java".. i am getting

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.3.2:java (default-cli) on project neo4j-movies: The parameters 'mainClass' for goal org.codehaus.mojo:exec-maven-plugin:1.3.2:java are missing or invalid -> [Help 1]

i am sure i am missing something silly.. please help..

Hello all,
I'm trying to run the server-extension java example, I have no experience with java and some help would be extremely appreciated. So far I have:

• forked the repository
• installed eclipse with m2e
• imported language-guides\java\server-extension\pom.xml into eclipse

Now I'm a bit stuck on how to run the code. Since from m2e I cannot do
mvn compile exec:java
I have tried the running the package with the following configuration:

But an error says that: The parameters 'mainClass' for goal org.codehaus.mojo:exec-maven-plugin:1.3.2:java are missing

If in the Run Configuration I add the paramenter "exec.mainClass" with value "example.extension.movies.MovieResource" then I get another error saying that there is no "main" method defined.

Am I missing something? What is the correct Run Configuration?

For Neo4jClient, how about summarizing and linking to these instructions?
https://github.com/Readify/Neo4jClient/wiki

Assuming @tathamoddie is ok with this?

Something similar for @mtranter's CypherNet ?

Hi, I am trying to just use the jdbc driver and I am getting No suitable driver found for jdbc:neo4j://localhost:7474/ with Neo 2.1.4

on Getting Started page
link book to
neo4j.com/graph-databases-book
NOT neo4j.com/books/graph-databases

I get an error with this application when I update the dependency of spring-data-neo4j-rest to 3.3.0.RELEASE.
java.lang.ClassNotFoundException: org.springframework.data.neo4j.core.UpdateableState
The error occurs when instantiating the graphDatabaseService

The URI scheme should be updated in https://neo4j.com/developer/aura-connect-cypher-shell/ to reflect the new URI scheme neo4j+s to connect to Aura instead of bolt+routing

Idea by @albertoperdomo

We have to split out all examples into separate repositories that live either side-by-side or with the driver and include them as submodules (if we want that)

To make it easy to test that new versions of the libraries are working

And possibly replace with Causal Cluster setup

And that the page will be updated and Bloom will be available natively on Aura.

There are many great resources for data visualization + Neo4j (a lot of D3 stuff). This the current just mentions D3 and moves on to commercial packages.

How about separating Graph Visualization into different files (similar to how the drivers are organized) and having an article per graph visualization method?

Content is sparse and may be out of date, but the two drivers have good documentation on their respective repos.

Can @jmcvetta and @wfreeman take a look at the Go page and suggest any updates or edits?

I'm trying to read the neo4j url from application.properties as I usually do in spring.boot projects. But here it doesn't work:

package movies.spring.data.neo4j;

import org.neo4j.graphdb.GraphDatabaseService;
import org.neo4j.graphdb.Relationship;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import org.springframework.data.neo4j.config.EnableNeo4jRepositories;
import org.springframework.data.neo4j.config.Neo4jConfiguration;
import org.springframework.data.neo4j.core.TypeRepresentationStrategy;
import org.springframework.data.neo4j.rest.SpringRestGraphDatabase;
import org.springframework.data.neo4j.support.typerepresentation.NoopRelationshipTypeRepresentationStrategy;
import org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.transaction.annotation.EnableTransactionManagement;

// tag::config[]
@EnableTransactionManagement
@Import(RepositoryRestMvcConfiguration.class)
@EnableScheduling
@EnableAutoConfiguration
@ComponentScan(basePackages = {"movies.spring.data.neo4j.services"})
@Configuration
@EnableNeo4jRepositories(basePackages = "movies.spring.data.neo4j.repositories")
public class MyNeo4jConfiguration extends Neo4jConfiguration {
    public MyNeo4jConfiguration() {
        setBasePackage("movies.spring.data.neo4j.domain");
    }

    @Value("${graph.db.url}")
    private String url;

    @Bean
    public GraphDatabaseService graphDatabaseService() {
        return new SpringRestGraphDatabase(url);
    }

    @Override
    public TypeRepresentationStrategy<Relationship> relationshipTypeRepresentationStrategy() throws Exception {
        return new NoopRelationshipTypeRepresentationStrategy();
    }
}
// end::config[]

Here is my application.properties file

graph.db.url: http://localhost:7474/db/data/

Also it fails to load it using @ConfigurationProperties approach.

A new guide on the differences between enterprise and community editions of Neo4j is needed for the get started section.

Focus should be on application requirements and user volume.

• remove "easy", "simple" etc. and superfluous text
• add a quick example for docker run with ports and auth
• add a quick example for a compose file
• clearly link to the docker hub https://hub.docker.com/_/neo4j
• fix broken link

Just a newbie in neo4j

Something along the lines:

• driver behavior in 4.0 changed, doesn't trust self-signed certs anymore, but encrypted=true by default
• if you don't have a proper trusted certificate (e.g. in Docker) you have to use encryption=false
• link to davids article for lets's encrypt

on the /cypher intro pages
so that people googling for it find it

Hey guys!

I was just notified that the example movie dataset you guys are using here looks like it’s the data that Spring.io used from their tutorial here. The Spring.io data was sourced from The Movie Database (TMDb) and while we have attribution on the tutorial, I’m wondering if we could have the same attribution on the Neo4j website.

Technically speaking our terms disallows sub licensing our data like this but as long as we get attributed I see no problem why you guys can’t continue to use the data as an example. The tutorial and data are perfect examples of what Neo4j can do.

Thanks!
