creating service

Hello,

I am developping a service with Axis2 like that :
I generate the cleint stub of the class that implements the services
and the in the server side I create the service like that :

if (context==null) {
try {
context = ConfigurationContextFactory.createConfigurationContextFromFileSystem(null, null);
} catch (Exception e) {
e.printStackTrace();

}
}
try
{
AxisService service=AxisService.createService(MyService.class.getName(), context.getAxisConfiguration(), RPCInOutAsyncMessageReceiver.class);

service.setActive(true);
context.getAxisConfiguration().addService(service);
SimpleHTTPServer server = new SimpleHTTPServer(context, 1500);
server.start();
} catch (AxisFault e) {
e.printStackTrace();

}

while (true) {
try {
System.out.println ("waiting 10 sec");
Thread.sleep(10000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

Is it correct?
wheb I excute it there is the following message:
11 févr. 2008 13:06:58 org.apache.axis2.deployment.ModuleDeployer deploy
INFO: Deploying module: addressing-1.2

In the client side I have the following application:

try
{
String eprString= "http://127.0.0.1:1500/axis2/services/MyService";
MyServiceMyServiceSOAP11PortStub stub=new MyServiceMyServiceSOAP11PortStub(eprString);

MyServiceMyServiceSOAP11PortStub.GetDataResponse repData=new MyServiceMyServiceSOAP11PortStub.GetDataResponse();
repData= stub.getData();
System.out.println("Reponse: "+ repData.get_return());
MyServiceMyServiceSOAP11PortStub.SetData testSetdata =new MyServiceMyServiceSOAP11PortStub.SetData();
testSetdata.setData("Modification");

stub.setData(testSetdata);

} catch (Exception e) {
e.printStackTrace();

}

}

but I have an error when I call a method like setData in this code or getData
for getData I have the following error:

*Exception in thread "Axis2 Task" java.lang.IllegalStateException: Response already committed*
*	at org.apache.axis2.transport.http.server.AxisHttpResponseImpl.assertNotCommitted(AxisHttpResponseImpl.java:85)*

And when I call a method whith no return value such as setData I have the following error:
Exception in thread "Axis2 Task" java.lang.UnsupportedOperationException: An access occurred that is not valid.

I don't undersatand perhaps there is something missing in the initialization of the server !!!!
Tanks for your help,
