> I'd lige to use xFire FW for making PayPal SOAP API calls. So i've generated
> Java classes from PayPal wsdl and i have wroten a small test class, that uses
> this classes.
> hier are links to PayPal wsdl and belonging XML Schemas:
> PayPal Schema tps://www.sandbox.paypal.com/wsdl/PayPalSvc.wsdl
> eBL Base Components https://www.sandbox.paypal.com/wsdl/eBLBaseComponents.xsd
> Component Types
> https://www.sandbox.paypal.com/wsdl/CoreComponentTypes.xsd
> I use in my client(see code below) some dummy params. They do not really
> matter. So i must receive some erros(Incorrect params, etc) as replay.
> I have used debugger, and i receive a soap response, but then an
> NullPointerException occures. So a can not read any errors or transaction
> details in my programm.
> .....
> The code(I ve generated java classes with eclipse plugin and choose package
> name jira.xfire. If you choose another package name, please change this name
