Call Client Java Proxy from Server Java Proxy

Question

Hi Gurus!!
I'm trying to call a Client Java Proxy from a Server Java Proxy.
Is possible to do this? I think must be possible.
I have called this Client Java Proxy from another application, and run ok.
I have tried to call it following the Guide to call Java Client Proxies:
                es.navantia.xi.mm.dispositivosRobotizadosKasto.MIRobotOut_PortTypeHome queryOutHome = null;
                es.navantia.xi.mm.dispositivosRobotizadosKasto.MIRobotOut_PortTypeRemote queryOutRemote = null;                     
                try {
                     //      Get naming context
                     Properties p = new Properties();
                     p.put(
                          Context.INITIAL_CONTEXT_FACTORY,
                          "com.sap.engine.services.jndi.InitialContextFactoryImpl");
                     p.put(Context.PROVIDER_URL, "myurl:50104");
                     p.put(Context.SECURITY_PRINCIPAL, "MMIGUEZ");
                     p.put(Context.SECURITY_CREDENTIALS, mypasswrod);
                     Context ctx = new InitialContext(p);
                     Object ref = ctx.lookup("RobotOut");
                     //      Look up jndi name of proxy bean
                    try {
                     queryOutHome =
                          (MIRobotOut_PortTypeHome) PortableRemoteObject.narrow(
                               ref,
                               MIRobotOut_PortTypeHome.class);
                    } catch (Exception e) {
                         throw new RuntimeException(e + "1");
                     //        Get Remote interface
                     queryOutRemote = queryOutHome.create();
                } catch (Exception e) {
                    throw new RuntimeException(e + "2");
but I get this error
"com.sap.aii.af.ra.ms.api.DeliveryException: Error invoking method mIRobotIn of proxy bean $Proxy351: es.navantia.xi.mm.dispositivosRobotizadosKasto.MIRobotOut_PortTypeHome: com.sap.aii.proxy.xiruntime.core.XmlInboundException: Error invoking method mIRobotIn of proxy bean $Proxy351: es.navantia.xi.mm.dispositivosRobotizadosKasto.MIRobotOut_PortTypeHome"
es.navantia.xi.mm.dispositivosRobotizadosKasto.MIRobotOut_PortTypeHome is the corresponding PortTypeHome to the Client Java Proxy.
I have tried to call too calling directly from the server Java Proxy to the method correcponding to the Client Java Proxy. The error I get is:
"com.sap.aii.af.ra.ms.api.DeliveryException: Error invoking method mIRobotIn of proxy bean $Proxy351: es/navantia/xi/mm/dispositivosRobotizadosKasto/DTRobot_Type: com.sap.aii.proxy.xiruntime.core.XmlInboundException: Error invoking method mIRobotIn of proxy bean $Proxy351: es/navantia/xi/mm/dispositivosRobotizadosKasto/DTRobot_Type"
Tha call to the client is:
es.navantia.xi.mm.dispositivosRobotizadosKasto.MIRobotOut_PortType clase = null;
es.navantia.xi.mm.dispositivosRobotizadosKasto.DTRobot_Type client_req = null;
es.navantia.xi.mm.dispositivosRobotizadosKasto.DTRobotResponse_Type client_res = null;
client_res = clase.mIRobotOut(client_req);
Please, any help will be useful.
Thanks and regards,
Manuel Míguez.

Hi,
Now I get another error message:
com.sap.aii.af.ra.ms.api.DeliveryException: Error invoking method mIRobotIn of proxy bean $Proxy351: es/navantia/xi/mm/dispositivosRobotizadosKasto/MITextoOut_PortTypeRemote: com.sap.aii.proxy.xiruntime.core.XmlInboundException: Error invoking method mIRobotIn of proxy bean $Proxy351: es/navantia/xi/mm/dispositivosRobotizadosKasto/MITextoOut_PortTypeRemote
Now, my source is:
  MITextoOut_PortTypeHome queryOutHome = null;
  MITextoOut_PortTypeRemote queryOutRemote = null;
  try {
//     Get naming context
Context ctx = new InitialContext();
//     Look up the EJB name in the environment
Object ref = ctx.lookup("java:comp/env/ejb/TextoOut");
// Object ref = ctx.lookup("java:comp/env/ejb/MITextoOut_PortTypeBean");
//     Cast to Home interface
     queryOutHome = (MITextoOut_PortTypeHome)
PortableRemoteObject.narrow(ref,
MITextoOut_PortTypeHome.class);
//     Get Remote interface
queryOutRemote = queryOutHome.create();
} catch (Exception e) {
System.out.println("RemoteException occurred: "+e.getMessage());
e.printStackTrace();
//return;
try {
      queryOutRemote.$messageSpecifier();
} catch (RemoteException e2) {
      // TODO Auto-generated catch block
      e2.printStackTrace();
DTTexto_Type Texto_type = new DTTexto_Type();
Texto_type.setTexto(req_texto);
DTTextoResponse_Type Texto_response = new DTTextoResponse_Type();
try {
     Texto_response = queryOutRemote.mITextoOut(Texto_type);
} catch (SystemFaultException e1) {
      // TODO Auto-generated catch block
      e1.printStackTrace();
} catch (ApplicationFaultException e1) {
      // TODO Auto-generated catch block
      e1.printStackTrace();
} catch (RemoteException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
I have tryed removing queryOutRemote.$messageSpecifier() and I get the error:
com.sap.aii.af.ra.ms.api.DeliveryException: Error invoking method mIRobotIn of proxy bean $Proxy351: es/navantia/xi/mm/dispositivosRobotizadosKasto/DTTexto_Type: com.sap.aii.proxy.xiruntime.core.XmlInboundException: Error invoking method mIRobotIn of proxy bean $Proxy351: es/navantia/xi/mm/dispositivosRobotizadosKasto/DTTexto_Type
Somebody knows what could be the cause of these errors?
Thanks and regards,
Manuel.
