    Resource don't work fine

    Sandro Villarroel Newbie

      Y have a problem with this Code



      @Stateless
      @Name("reporte")
      public class ReporteBean implements Reporte{
      
              @Logger
              Log log;
      
              @In
              Identity identity;
              
              @Resource(mappedName = Constantes.DATA_SOURCE)
              protected DataSource dataSource;
              
              public ReporteBean() {
              }
              
              public void crearArchivo() {
      
                      Connection conn = null;
                      
                      try {
                              conn = dataSource.getConnection();
                      } catch (Exception e) {
                              log.error(" ================= ERROR en ReporteBean.crearPdf ", e);
                      } finally {
                              try {
                                      if (conn != null) conn.close();
                              } catch (SQLException sqle) {
                                      log.error(" ========================= ERROR AL CERRAR LA CONNECCION CON LA BASE DE DATOS ReporteBean.crearPdf ", sqle);
                              }
                      }
              }
      }



      When I Call Method crearArchivo() from regionList y have a NullPointerException in this line: conn = dataSource.getConnection(); but I have another Class like This




      @Stateless
      @Name("reportesFt")
      public class ReportesFtBean extends ReporteBean implements ReportesFt {
      
              public ReportesFtBean() {
              }
              
              @Override
              public void listadoRegiones() {
                      this.crearArchivo();
              }
      ...
       



      And When i call method from listadoRegiones() it works fine, somebody may explain me where is the error, I would call method from regionList(), because I need make more reports.


      thanks in advance for your help.
