I have just downloaded Linkurious v1.2.7 on Windows 7
Neo4j is v2.2.0-M02 running on the same localhost.
Neo4j works without issue. I have a .NET WebService project that can query the HTTP endpoint at http://localhost:7474/db/data without problem.
Linkurious is installed correctly (presumably). I have modified the graphdb.json file with the localhost url and username and password for Neo4j.
after some troubleshooting Linkurious can see that the Neo4j database is running but it throws the error:
"The graph database Rest API did not respond. Please check its connection settings & log trace."
I am not seeing any activity from linkurious in the neo4j console.log.
Anyone have any leads for me? I was hoping to work through the weekend to get this project done.
as Christophe Willemsen indicated, Linkurious 1.2.7 does not yet work with Neo4j 2.2.0.
You can now access a new version called Linkurious Starter that fully supports Neo4j 2.2.0. Go to https://linkurio.us/my-account/ to download it.
Let me know if it solves your issue!

Please I am trying to access the Neo4j database via its browser. I have used both bolt//:localhost:7687 and http//:localhost:7474, and Username: "neo4j" and Password:"neo4j" but with no success. I can't even start a database instance.
I have uninstalled and reinstalled Neo4j on my computer; I have updated Powershell on my Windows 8.1 computer, yet I keep getting an error message whenever I try to run the Movie database in the desktop.
I have also looked into the log.log file, but can't seem to find anything other than that I should update Powershell, which I have done.
I have corresponded with a relations officer at Neo4j, over 30 emails, and still I can't access Neo4j database.
Could it have anything to do with my web browser? I use Mozilla Firefox.
Because I am unable to successfully connect to Neo4j database, I can't call the api in R Studio and run cypher queries.
Does Neo4j have a web version, which I could use, since the desktop version isn't working?
Please does anybody have any idea or advice on what I could do to resolve this problem? I am really exasperated right now.
I want to create a dump of the database that JQAssistant creates with a scan. So far i have tried to do this with the integrated server and by connecting jqassistant to a running database.
The problem with the integrated database is that i can't access a shell and therefore i don't know how i could create the dump.
Connecting to the running database also didn't work. I assume the problem here is the encryption, my server is running local and trying to connect to it with
jqassistant.sh scan -f my-project.jar -storeUri bolt://localhost:7687 -storeUsername neo4j -storePassword secret
which is the example from the jqa tutorial throws the error:
javax.net.ssl.SSLHandshakeException: General SSLEngine problem
so i assume i can't connect without ssl encryption.
I am using Neo4j server 3.5.15 and JQAssistant Commandline Tool version 1.9 which uses an integrated Neo4j 3.5.14 server.
If you can give me an new idea how to create a data dump out of the scan or how to fix one of the two given problems i would appreciate that a lot!
Thanks in advance!
I couldn't figure out a way to export the database with the commandline tool, but with the maven plugin. If you setup a maven project and include jqassistant as a plugin it offers you the option "export-database" which creates a Cypher script.
So I have been trying to use Graphileon for my Neo4j graph db. I have my Neo4j service set up and running. But when I try to start Graphileon and connect to my Neo4j db, it keeps saying "Could not connect. Connection error check your settings." even when all of the settings entered, are correct. I tried reinstalling Neo4j, I tried reinstalling Graphileon, but to no avail. I am using Neo4j Community edition, and Graphileon personal edition, on Ubuntu 18.04.
Is there something I'm missing? Is there some configuration that I'm missing for Graphileon?
Graphileon 2.7.1 is available now, with support for Neo4j 4.0 . You can request a download link from here https://graphileon.com/request-graphileon-application/
I have neo4j 3.2.4 installed on a Ubuntu instance. After installing, all I've done to start neo4j is "sudo neo4j console" which directs me to a web interface. Unfortunately, I must connect to the web interface on a different computer which I can do via localhost:7474 or https://localhost:7473. (There is some port forwarding required.) Both get me to the landing page. There I am asked to enter a password (the default one) to connect to the database but I then get the error - "ServiceUnavailable: WebSocket connection failure. Due to security constraints in your web browser, the reason for the failure is not available to this Neo4j Driver ..."
The only site that suggests a solution is here. The suggested solution is to uncomment "dbms.connector.bolt.address=0.0.0.0:7687" in the neo4j.conf file which I did. I then restarted neo4j but I keep on getting the same error.
FWIW - telnet 127.0.0.1 7687 works so connecting to Bolt seems to be fine.
There is also a Github issue referencing this problem but no specific suggested solutions. (Neo4j - issue 504)
Any suggestions greatly appreciated.
Thank you for the information InverseFalcon. FWIW I got things to work by switching over to Firefox where I had also set up FoxyProxy. (So not sure if it was Firefox or FoxyProxy that helped - but would a place to start for anyone else having trouble.)
If you are able to open neo4j web interface, then goto settings -> Network connection section and then check the checkbox that says "Do Not Use Bolt".
After installing the Community edition 3.3.5 on Windows I was getting the same issue as mentioned above, using Chrome. After reading Greg's solution using Firefox, I switched to Internet Explorer and it worked fine.
I was given a graph db I must open with Neo4j. Installed community version Neo4j-2.2.0-M02 on Win7 Ultimate laptop successfully. When I tried to start the server, after pointing to the graph db, I get the following error:
Starting Neo4j Server failed:
Component org.neo4j.server.database.LifecycleManagingDatabase#325ce05c was successfully initialized, but failed to start. Please see attached cause exception.
Logged in as windows local admin. Windows FWall is off. There's no antivirus SW installed on the machine. Local admin has full perms on entire root drive. When I point to the default db, Neo4j server starts normally and I can browse http://localhost:7474/ without a problem.
Any lead will be appreciated.
The aforementioned error message was the result of using a Neo4j version different to the one the graph db was originally developed. In particular, the original graph db was developed in ver 2.0.4 Community that due to my lack of knowledge I was trying to run on an installation of Neo4j ver. 2.2.0-M02 (for development only).
The code owner enlightened me to the fact and an attempt to bring up the graph db on ver. 2.0.4 Community was successful.
Thanks for your support.
Delete the folder "c:\Users\Yourname\MyDocuments\Neo4j"
I removed the plugins that were loaded from <NEO4J_HOME>/plugins as they were also loaded from under <DATABASE_HOME>/plugins
