Subject: Jini+JavaSpace05 to j2ee

Hi all,

Anyone know what is the best practice for connect Jini+JavaSpace05 to j2ee 
(ejb,servlet or J2EE-JCA).

My code is the next:

public class Jini
  extends HttpServlet
  implements DiscoveryListener,LeaseListener
{
  public void init(ServletConfig config)
    throws ServletException
  {
    super.init(config);
    try
    {
      Long tiempo=System.currentTimeMillis();
      System.setSecurityManager(new RMISecurityManager());
      LookupDiscovery descubrir=
	new LookupDiscovery(LookupDiscovery.ALL_GROUPS);
      descubrir.addDiscoveryListener(this);
      Thread.currentThread().sleep(Lease.FOREVER);
    }
    catch(RemoteException e)
    {
      System.out.println(e.toString());
    }
    catch(Exception e)
    {
      System.out.println(e.toString());
    }
  }

  public void service(HttpServletRequest request,
		      HttpServletResponse response)
    throws ServletException,IOException
  {


    PrintWriter out=response.getWriter();
    out.write("Hola");
    out.close();
  }

  public void discovered(DiscoveryEvent evt)
  {
    try
    {
      ServiceRegistrar[] registrars=evt.getRegistrars();
      for(int n=0;n<registrars.length;n++)
      {
	System.out.println("Descubriendo");
	ServiceRegistrar registrar=registrars[n];
	ServiceTemplate tmpl=new ServiceTemplate(null,new Class[]
	    { JavaSpace05.class },null);
	JavaSpace05 jsprueba=(JavaSpace05)registrar.lookup(tmpl);
	if(jsprueba!=null)
	{
	  System.out.println("Escribiendo grid");
	  Factura factura=new Factura();
	  factura.nombre="prueba1";
	  factura.nombre="valor1";
	  Entry prueba=factura;
	  jsprueba.write(prueba,null,Long.MAX_VALUE);
	}
      }
    }
    catch(RemoteException e)
    {
      System.out.println(e.toString());
    }
    catch(TransactionException e)
    {
      System.out.println(e.toString());
    }
  }

  public void discarded(DiscoveryEvent evt)
  {
    System.out.println("Descartando "+evt.toString());
  }

  public void notify(LeaseRenewalEvent evt)
  {
    System.out.println("Expirado"+evt.toString());
  }
}

Best regards,
Luis Arce
