The Jena API call as you wrote it lists only triples with literals, and not 
URIs, in the object position. So you can use it to find the triples with object 
"Sandy Smith", but not with object 
<http://localhost:2020/vocab/resource/example>. To list statements with URIs in 
them, do something like:

  Model myD2RQ = new ModelD2RQ(...);
  Resource exampleClass = myD2RQ.createResource(
        "http://localhost:2020/vocab/resource/example";);
  StmtIterator it = listStatements(null, RDF.type, exampleClass);

This should return two statements, as your table contains two records AFAICT.

Right — Jena contains a couple more jars that D2RQ doesn't need, and hence they 
are not included in the D2RQ download. The cleanest way to avoid this is to 
download the version of ARQ that D2RQ uses, as indicated by the name of D2RQ's 
/lib/arq-X.Y folder, and take all jars from there.

I've updated the docs at http://d2rq.org/jena to reflect this. The page there 
had some outdated information on other issues as well (e.g., the logging 
subsection) that I've fixed too.

Best,
Richard
