It works with the second query from your initial mail; i.e. that one:

PREFIX foaf: <http://xmlns.com/foaf/0.1/>
SELECT ?i ?p WHERE {
 ?i ?p foaf:Person .
}

You may have to increase the number of maximal depth of link following a bit. 
If I execute the query without Sindice support --e.g. using the command line 
call

  bin/semwebquery  --maxsteps 5 --sparqlfile query.rq

where 'query.rq' contains the query-- then I get a result that originate from 
the FOAF vocabulary definition only. However, if I enable Sindice support 

  bin/semwebquery  --maxsteps 5 --sindice --sparqlfile query.rq

then I get loads of results from peoples' FOAF profiles. The same should be 
possible if you use SWClLib as a library in your Java code.

Greetings,
Olaf
