I have been attempting to create a simple web service capable of connecting to the Quickbooks web connector with quickbooks 2012 on windows 7.

The implementation is clearly described in the programming guide (http://developer.intuit.com/qbsdk-current/doc/pdf/qbwc_proguide.pdf).

I keep getting the same error as “Authentication Failed” and “Object reference not set to instance of Object” at the authenticate method. I first created the sample web service in java using Eclipse.

The problem is in the authenticate method.

I also turn on the VERBOSE mode for Web Connector.

Below is the Complete Log

    You’re using the wrong namespace for your SOAP service. Fix your namespace issues, and post your code if you continue to have trouble.

    Your namespace should be:
    http://developer.intuit.com/

    That makes me think that you likely didn’t generate this from the WSDL either, which would probably solve your issues.
