I'm trying to build a small semantic web application using Jena framework, JSP and JAVA. I have a remote SPARQL endpoint and I've already written a simple query which works fine but now I need to use some parameters. Here is my code so far:

final static String serviceEndpoint = "http://fishdelish.cs.man.ac.uk/sparql/";

String comNameQuery = 
        "PREFIX fd: <http://fishdelish.cs.man.ac.uk/rdf/vocab/resource/> " +
        "SELECT ?name ?language ?type" +
        "WHERE { ?nameID fd:comnames_ComName ?name ;" +
        "fd:comnames_Language ?language ;" +
        "fd:comnames_NameType ?type ." +
        "}";

Query query = QueryFactory.create(comNameQuery);  
QueryExecution qe = QueryExecutionFactory.sparqlService(serviceEndpoint,query);

try {
    ResultSet rs = qe.execSelect();
    if ( rs.hasNext() ) {
        System.out.println(ResultSetFormatter.asText(rs));
    }
} 
catch(Exception e) { 
    System.out.println(e.getMessage());
}
finally {
    qe.close();
}

What I want to do is to parameterized ?name. I'm new to Jena and I'm not really sure how to use parameters in a SPARQL query. I would appreciate it if someone could help me with this.
