Examples of org.apache.axis.client.async.Listener

org.apache.axis.client.async.Listener
This is the asynchronous call back interface used by the Call object to receive responses and faults from the AsyncCall implementation. By default, the Call object will use default impl's of this interface to handle the basic waitForReturnValue() and getAsyncStatus() operations. Advanced users can specify their own callback interface implementations by setting the ASYNC_CALL_LISTENER property on the Call object. By doing so, the user becomes responsible for handling the state of the async call and all of the async support functions (getAsyncStatus, getReturnValue, getReturnedFault, waitForReturnValue) become useless. @author James Snell (jasnell@us.ibm.com)

        if (getAsyncStatus() == ASYNC_RUNNING) {
          // TODO: we need to throw an error 
          // We can't have two async operations messing with this
          // single Call object
        }
        Listener listener = (Listener)getProperty(AsyncCall.ASYNC_CALL_LISTENER);
        if (listener == null) {
          listener = new Listener() { // Create default RPC listener
            public void invokeComplete() {
              setAsyncStatus(ASYNC_READY);

            public void onResponse(final MessageContext context)
