The very first thing a have tried was simple servlet with JDBC DataSource Resource injection... Something like... public class jg extends HttpServlet {     @Resource(name = "java:/comp/env/jdbc/sisds")     DataSource sistestds;     protected void processRequest(HttpServletRequest request, HttpServletResponse response)             throws ServletException, IOException {         PrintWriter out = response.getWriter();         try {             response.setContentType("text/html;charset=UTF-8");             // obtaining connection             Connection conn = sistestds.getConnection();             // preparing and executing statement             PreparedStatement st = conn.prepareStatement("SELECT ip FROM jail");             st.execute();             // printing resultset             ResultSet rs = st.getResultSet();             while (rs.next()) {                 out.println(rs.getString("ip"));             }         } catch (SQLException ex) {             Logger.getLogger(jg.class.getName()).log(Level.SEVERE, null, ex);         } finally {             out.close();         }     } ... (the method gets called from appropriate get/post... etc. calls)... I have simple table containing list of some virtual servers (jails) and want to list their IP addresses. This snippet of code would work in GlassFish, ... but JBoss reports that mappedName should be used... in the @Resource injection... In fact... it functions with the mappedName... but I want my application to be as portable as possible and I'd like to avoid using platform specific things like mappedName.... Should mention that I am using JBoss AS 5.0.1 GA on Linux... Any help is welcome...
