Hi Fan,

The tutorial is a bit dated, so it might be confusing/incorrect.

You have a couple options:

1. You could start using the Vagrant vm that I'm putting together as a "Rya
Quickstart VM".

It's a bit rough right now, and it doesn't have Hadoop or MapReduce (so you
can't do the bulk load), but it does have the script you mentioned for
loading N-Triples.  An early copy of the Vagrantfile is here [1].

It'll take about 30 minutes to build the VM, but once you do, you'll have
the rya web endpoint up and running here [2] and you can ssh into the box
to load data.  Once you ssh into the machine, you can run 'java
to load n-triples files.  Infact, you that script will take a "batchSize"
parameter to split a large ntriples into small loads.

2. We can help you debug your current vm.

The first step would be to try to hit this webpage [3] and see if the
sparql query page loads.  Also note that the URL you provided has an extra
"/" in it and you should try [4].

If those load properly, then the issue might be the LoadDataServletRun file
itself (I haven't tried the one you mentioned), but you could try the new
one located at the bottom of the Vagrant file.

If those links do not load properly, please send us your tomcat logs and
we'll take a look to see what's up with tomcat.

[3] http://localhost:8080/web.rya/sparqlQuery.jsp
[4] http://localhost:8080/web.rya/loadrdf?format=N-Triples
