Oh...thanks a lot..God bless you..now I can convince my boss that since Jena 2.6.4 does not support N-Quads therefore we should move to Jena 2.13.0
Also I found here (http://www.rpmseek.com/rpm/jena-2.6.4-5.fc18.noarch.html?hl=com&cs=icu4j:RE:0:0:0:0:0:9914798) that Jena supports "Reading and writing RDF in RDF/XML, N3 and N-Triples" (..and not n-quads). This gives me enough evidence to convince my boss that Jena 2.6.4 does not support N-Quad.
