Hi,

As I posted in this thread: http://boards.developerforce.com/t5/Security/Using-Partner-WSDL-API-with-OAuth/td-p/302435, Simon mentioned I just need to replace sessionId with access token in the SessionHeader. When i set property to binding in binding._setProperty(SoapBindingStub.ENDPOINT_ADDRESS_PROPERTY, service_url);, what url should I use here? Before I use "https://www.salesforce.com/services/Soap/u/21.0". With OAuth, I have instance_url as "https://na3.salesforce.com" for one user. Should I use this instance_url instead of previous soap url?

Thanks,

Michael
