Thanks for your response. I am using axis 1.3. Following is my callback
handler generated from wsdl2java.
/**
* DMTServiceCallbackHandler.java
*
* This file was auto-generated from WSDL
* by the Apache Axis2 version: 1.3 Built on : Aug 10, 2007 (04:45:47 LKT)
*/
package org.tempuri;
/**
* DMTServiceCallbackHandler Callback class, Users can extend this class
and implement
* their own receiveResult and receiveError methods.
*/
public abstract class DMTServiceCallbackHandler {
protected Object clientData;
/**
* User can pass in any object that needs to be accessed once the
NonBlocking
* Web service call is finished and appropriate method of this CallBack
is called.
* @param clientData Object mechanism by which the user can pass in user
data
* that will be avilable at the time this callback is called.
*/
public DMTServiceCallbackHandler(Object clientData) {
this.clientData = clientData;
}
/**
* Please use this constructor if you don't want to set any clientData
*/
public DMTServiceCallbackHandler() {
this.clientData = null;
}
/**
* Get the client data
*/
public Object getClientData() {
return clientData;
}
/**
* auto generated Axis2 call back method for Hello method
* override this method for handling normal response from Hello
operation
*/
public void receiveResultHello(org.tempuri.HelloResponseDocument result)
{
}
/**
* auto generated Axis2 Error handler
* override this method for handling error response from Hello operation
*/
public void receiveErrorHello(java.lang.Exception e) {
}
// No methods generated for meps other than in-out
}
I see there are methods for receiveResultHello and receiveErrorHello. My WCF
duplex webservice is
namespace DMTWCFService
{
public interface IDMTServiceCallback
{
[OperationContract]
void HelloCallback();
}
[ServiceContract(CallbackContract = typeof(IDMTServiceCallback))]
public interface IDMTService
{
[OperationContract]
string Hello(string message);
}
[ServiceBehavior(ConcurrencyMode=ConcurrencyMode.Reentrant)]
public class DMTService : IDMTService
{
public string Hello(string message)
{
Console.WriteLine("Message received " + message);
System.Threading.Thread.Sleep(5000);
IDMTServiceCallback Callback =
OperationContext.Current.GetCallbackChannel<IDMTServiceCallback>();
if(Callback!=null)
Callback.HelloCallback();
System.Threading.Thread.Sleep(5000);
return message;
}
}
}
The WCF duplex contract also says that the client should implement the
interface IDMTServiceCallBack and should provide an implementation for
HelloCallback() method. Now when I generate my proxy code I dont get any
receiveResultHelloCallBack and receiveErrorHelloCallback. Which means I cant
do anything if the WCF webservice returns with a response. I am confused as
to how should this be done. Is this a limitation with the -xmlbeans
databinding? Should I use adb? I shall highly value your response. Thanks
