GraphML file readable via Java but not Gremlin console?

[Rowan Johnson]

Hello,

I'm a bit of a newbie to TinkerPop3 so please excuse any silliness on my part.

TL;DR: I can open a graphml file I previously wrote in my Java app but not in the Gremlin console. Why?

I have a Java program that is creating a graph and writing it to a local file using the following code: 

private static TinkerGraph tg = TinkerGraph.open();
<code creating tg graph>
tg.io(IoCore.graphml()).writeGraph("query-result.xml");

I am then able to launch the program again and load the data using:

tg.io(IoCore.graphml()).readGraph("query-result.xml");

If it makes a difference, the file is a bit weird and quite big; I've got 224,000 nodes and 0 edges, mostly because edge creation has been too time-intensive so far. The file is about 142 megabytes.

The problem is, I would like to be able to load this xml file into the TinkerGraph console. I moved this xml file to the data file in tinkergraph console. Yet, when I run 

graph = TinkerGraph.open()
graph.io(IoCore.graphml()).readGraph("data/query-results.xml")

I get the message back that there is "No such file or directory", even though the file exists and I can print it out. Whereas, trying to load any of the pre-provided data in the data package works just fine for me.

Any ideas as to why this is happening?

Cheers,

Rowan

Ok interesting update - if I run cp <directory to file> . in the console/data directory, suddenly it works? Is there some special property of the data folder I'm not aware of?

Not sure what might be wrong, but probably just a pathing problem of some sort. If you start the Gremlin Console with:

bin/gremlin.sh 

then i would expect this line to work:

graph.io(IoCore.graphml()).readGraph("data/query-results.xml")

where the /data directory is at the same level as /bin
