[펌] HttpURLConnection 을 이용하세요

// 해당 URL을
URL url    = new URL( "http", host, port, dir + "?member_id=" + memberID );
// 연결하고
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
// 응답이
int responseCode = connection.getResponseCode();
                
String line    = "";
// 성공이면
if ( responseCode == HttpURLConnection.HTTP_OK )
{
BufferedReader  br      = new BufferedReader( new InputStreamReader( connection.getInputStream() ) );
    // 해당 URL의 끝을 볼때까지 라인을 읽어서                
    while ( ( line = br.readLine() ) != null)
    {
        result    += line;
    }                    
}

result 값을 파싱하시면 될겁니다.
