Trying to import neo4j databases -> no effect

Post by casibus » 22 Jan 2012 14:26

Hi there,
today I found Gephi and I am looking forward to using it with some neo4j databases. So I downlaoded gephi and installed it on a windows 7 machine. I activated the neo4j plugin just like in the video (https://gephi.org/plugins/neo4j-graph-database-support/) and tried to fully import one database, but nothing happened after selecting the folder and pressing "open". So I tried another very small one and got the same behavior... Also the same behavior resulted, when I tried traversal import. Interestingly when I created two nodes within gephi, connected them and exported this by the neo4j plugin, I was able to import that database.
The neo4j databases were created by neo4j.rb by Andreas Ronge with ruby. Maybe the resulting format is not readable by Gephi? Someone has an idea? :?: I got no error message and found no similar problem discription out there.
It would be great, if someone can help me. Thank you.

Bump. I too am having this same issue. Initially I tailed my message.log file for any java-related errors and saw that the database was initially closed off in an unclean way. However, I generated a new database that produced no errors or issues and still get the same response. I see no visual or log-based errors. Any ideas?

I have tried this with neo4j 1.8 on both Mac OS X and Windows XP.

Another Bump !
I got this problem which looks the same :

Gephi 0.8.2-beta - Neo4j 2.0.1 - Windows 8

I do File -> Neo4j Databse -> Full import
then I browse to this folder and click open : C:\Users\me\Documents\Neo4j\default.graphdb
then nothing hapen.

Note that I didn't found any data/graph.db I see reference in others post, I only can find this folder default.graphdb which contains lots of files that don't display when browsing from the Gephi dialog.

And another bump.

I am having these exact issues.

Has anyone here possibly figured out how to get a neo4j database properly working in Gephi?

Hi.

I just imported a Neo4j database (sort of). I ran out of room because my database was too big, but I at least got further than it seems that you all have gotten. Your problem might be that the Neo4j import plugin requires a Neo4j 2.1.0 database. Another possible problem that I had to deal with was java version incompatibility. If you are running gephi with java 6 you will get a failure, because the Neo4j plugins require java 7. I also found that the gephi launch scripts seem to prefer java 6, so you must set the jdkhome argument (or gephi.conf parameter) to the path to the java 7 JDK folder.

Hope this helps.
