Calling ASP.NET Web Service from Java client using Axis

Asked by Triskelion in Java Standard Edition, New to Java Programming, Web Services Description Language

...new to Java and just messing around...
I am attempting to call the "BigAdd" method on this page:
http://www.meizlik.com/Service.asmx

I get a multitude of errors no matter what I try; the latest of which is a NullReferenceException:
    at BigAddService.Bob_Services.BigAdd_Method(String a1, String a2)
    at BigAddService.Bob_Services.BigAdd(String addend_1, String addend_2)

I just want to see this work.  Any suggestions or answers?Start Free Trial
