Jena-2.11.2 QueryParseException: Encountered " "as" "as ""

[Wei Zhang]

Hi All,

I have encountered a problem when using Jena. The query can be executed on 
http://dbpedia.org/sparql/ correctly, but failed in Java code.
Could anyone help me?  I tried find solution online but failed. Some links said 
it's the version problem, but I think 2.11.2 is new.

Here's the code
"
String QueryOrg= "select distinct ?Apro (count(distinct ?n0) as ?Num) " +
                           "where{  " +
                           "?n0 a 
<http://dbpedia.org/ontology/TelevisionStation>. " +
                           "?n0 a 
<http://dbpedia.org/class/yago/CBSNetworkAffiliates>.  " +
                           "?n0 ?Apro  ?o.  " +
                           "FILTER IsLiteral(?o) " +
                           "} " +
                           "group by ?Apro   " +
                           "having(count(distinct ?n0) as ?tt >1)  " +
                           "order by DESC(?Num) " ;

Query query = QueryFactory.create(QueryOrg);
// I have not do anything yet
"
The error:
"Exception in thread "main" com.hp.hpl.jena.query.QueryParseException:
