IO2GResponseListener.onRequestFailed

In order to process a notification about a request failure, an instance of the class implementing the IO2GResponseListener interface must be subscribed to a session object. It is accomplished by calling the O2GSession.subscribeResponse method.

Proccess notification about a request to get open positions [hide]

    // Create a request to get open positions information
    O2GRequestFactory requestFactory = session.getRequestFactory();
    if (requestFactory != null) {
        O2GRequest request = requestFactory.createRefreshTableRequest(O2GTableType.TRADES);
        responseListener.setRequest(request.getRequestId());
        session.sendRequest(request);
        Thread.sleep(1000);
    }
 
    // Set request in the implementation of IO2GResponseListener interface
    public void setRequest(String requestID) {
       mRequestID = requestID;
    }
 
    // Implementation of IO2GResponseListener interface public method onRequestFailed
    public void onRequestFailed(String requestID, String error) {
        if (requestID.equals(mRequestID)) {
            System.out.println("Request failed. requestID= " + requestID + "; error= " + error);
        }
    }

Parameters
`requestId`	The identifier of the failed request. A session object may send multiple requests (see the O2GSession.sendRequest method). The method receives notifications of all the requests that have failed. To make sure you are getting a notification about a particular request, you must check if the value of this parameter matches the value obtained by calling the `O2GRequest`.`getRequestId` method. For details, see the example below.
`error`	The server error message. For the list of errors that may be generated during an order processing, refer to the Order Execution Errors section.
