It isn't very difficult to query using java's httpurlconnection [1] and xml facilities to deal with the results of SELECT and ASK. Just construct a url like "http://example.com/sparql?query=" + URLEncoder.encode(queryString, "UTF-8") However if you want something full featured there is ARQ's sparqlService [2], which will deal with the messy details for you.
