Jena ARQ API - how to set timeout in Java

[Dalkandura Arachchige Gunaratna]

Hi,
   I am using Jena  ARQ API to query DBpedia dataset using a sparql endpoint. I 
want to set  the timeout limit for querying using a java program so that the 
program  will not crash if sufficient timeout is set. My intention is to have a 
 simple loop to handle so that if an exception happens, the query will be  
re-done.

   I have come across a code sample to set timeout in  the internet and I am 
not sure whether this works correctly. Is this  correct or there is any other 
way of doing this?

        QueryEngineHTTP qexec = (QueryEngineHTTP) 
QueryExecutionFactory.sparqlService(
                strSparqlEndpoint, qExecuteQuery);
        qexec.addParam("timeout","10000");
