Hi, I have been struggling for a few days now to get the simple Graph Of The Gods viewable in Dog House/callable with REST API. I haven't been successful and I hope someone can point me in right direction. I believe it's something silly I have overlooked, I'm very new everything and I'd appreciate any help.
I have followed the getting started guide (
https://github.com/thinkaurelius/titan/wiki/Getting-Started) and am able to traverse the graph as per the guide. I have created the graph in a folder called graphtest/titan, which appears in the titan home directory alongside the bin, conf, doc, etc. I then followed the Rexster Graph Server guide (
https://github.com/thinkaurelius/titan/wiki/Rexster-Graph-Server) and edited the rexster-cassandra-es.xml to include the graph as follows:
<graph>
<graph-name>titanexample</graph-name>
<graph-type>com.thinkaurelius.titan.tinkerpop.rexster.TitanGraphConfiguration</graph-type>
<graph-location>graphtest/titan</graph-location>
<graph-read-only>false</graph-read-only>
<properties>
<storage.backend>local</storage.backend>
<storage.buffer-size>100</storage.buffer-size>
</properties>
<extensions>
<allows>
<allow>tp:gremlin</allow>
</allows>
</extensions>
</graph> When I go to my server:8182 I can see Dog House and open it up, on the left hand side is titanexample. I click on that and it shows "titanexample - titangraph[local:graphtest/titan]". However when I click on the Browse Vertices or Browse Edges buttons it's flickers for a split second but nothing is shown. An example of the response is:
9 * Server out-bound response
9 < 200
9 < Content-Type: application/vnd.rexster-v1+json; charset=UTF-8
9 < Access-Control-Allow-Origin: *
9 <
{"version":"2.4.0","results":[],"totalSize":0,"queryTime":2.003002}
I have also been provided another already created graph which I have tried to point to in the rexster-cassandra-es.xml, but i get the same thing where it appears in Dog House but I get empty results when i try to do anything on it. That graph has 1000s of nodes and was tested before provided to me. I am using Titan 0.4.4 as that is also what has been provided to me.
Hopefully somebody can give me some advice on what to check next?
