I want to query from dbpedia using their sparql interface (http://dbpedia.org/sparql)

I want to get the abstract of

http://dbpedia.org/page/Herbie_Mann

I know that I have to call abstract ontology

http://dbpedia.org/ontology/abstract

and my final sparsql query is like following :

SELECT ?abstract
WHERE {
{ <http://dbpedia.org/page/Herbie_Mann> <http://dbpedia.org/ontology/abstract> ?abstract}
}

but yet I'm not able to see anything.

please help me as I am beginner in semantic web!
