[namedgraphs] problem using ng4j

[wenlei z. <wen...@gm...>]

Hi, guys
When I execute "semwebquery -sparqlfile tabulator-devs.sparql
-retrieveduris". I get such result:

-----------------------------
| name | mbox | projectName |
=============================
-----------------------------
Successfully dereferenced URIs:

http://usefulinc.com/ns/doap
--------------------------------

The tabulator-devs.sparql's content is as same as Example1 in
http://www4.wiwiss.fu-berlin.de/bizer/ng4j/semwebclient/index.html#sindice .
However, the result is not the same as the tutorial's.

I don't know where the problem comes from. Does anybody know the answer?
Thank you very much!
