Re: Problem with two services in a serviceGroup with scope soapsession sharing ServiceGroupContext

[Manuel Lozano Melero <ml...@cc.upv.es>]

I am new in AXIS2 and the problem is in this configuration:

- Two clases, in each class there is a service with operations to invoke.
- The first class(service Autenticacion) it is used to autenticate the 
user in the application
- The second class(service Directorio) do a job, but it validates that 
the user is autenticated
- I want a unique ServiceGroupContext where the first service 
"Autenticacion" puts a valid "sessionId" if the user+password is valid.
- Then a new request to the second service "Directorio" gets from 
"ServiceGroupContext " the "sessionId"
-- The problem is that there are two contexts!!! see the details...... 
Thanks



I have this service.xml configuration:

<serviceGroup>
   <service name="Autenticacion" scope="soapsession">
       <Description> Servicio WEB de autenticacion</Description>
       <parameter name="ServiceClass" 
locked="false">es.upv.wsasic.app.Autenticacion</parameter>
       <messageReceivers>
           <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only"
               
class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
           <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out"
               class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
       </messageReceivers>
   </service>
   <service name="Directorio" scope="soapsession">
       <Description> Servicio WEB de directorio</Description>
       <parameter name="ServiceClass" 
locked="false">es.upv.wsasic.app.Directorio</parameter>
       <messageReceivers>
           <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only"
               
class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
           <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out"
               class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
       </messageReceivers>
   </service>
   <module ref="addressing" />
</serviceGroup>

I have generated the Stubs from the WSDL :
 
  wsdl2java.bat -uri Autenticacion.wsdl -p es.upv.wsasic.cliente -d adb -s
  wsdl2java.bat -uri Directorio.wsdl -p es.upv.wsasic.cliente -d adb -s

Then i have incluided in both stubs constructors:
.............
       _serviceClient.engageModule("addressing");
       _serviceClient.getOptions().setManageSession(true);

In the service "es.upv.wsasic.app.Autenticacion" class i have a method 
to autenticate a user in my application. This is the first service 
request .

    public byte[] obtieneSessionId(String user,String password){
      .... do validation and return a String "sessionId" variable if 
autentication success
            ServiceGroupContext 
session=MessageContext.getCurrentMessageContext().getServiceGroupContext();       

       session.setProperty("sessionId", sessionId); // I want to save 
this value
       return AESCipher.encode(sessionId);
  }


And in the other service "es.upv.wsasic.app.Directorio" class i have a 
method, but before to execute the request(this is the second service 
request) i validate that the user is autenticated in the application in 
this way.

   public Person getInfoPerson(String sessionId, String dni) throws 
ServicioException{          
     ServiceGroupContext sesion = 
MessageContext.getCurrentMessageContext().getServiceGroupContext();
        String sessionIdAES = (String) sesion.getProperty("sessionId");

        /*
             But in this point "sessionIdAES" is null and "sesion" has a 
diferent ServiceGroupContext, it seems that has two ServiceGroupContext
             each for service "Autenticacion" and "Directorio", and i 
only want a ServiceGroupContext for the two services in the 
"soapsession" scope.
             This is the problem, how to share a unique 
ServiceGroupContext in this scope!
             If i call the same "Atenticacion" service more than one 
time, the ServiceGroupContext for this service is unique.
             And then i call "Directorio" more than one time, and the 
new ServiceGroupContext for this service is unique for "Directorio" but 
this
             situation is the problem, there are two different contexts.
