Re[2]: Problem using deployed Axis web services

[Martin Wunderlich]

Thanks a lot, Dies, for your detailed explanation! I understand the
principles behind the workings of WSDL2Java much better now. This
whole thing has cost me the better part of an entire week. Then again,
it's my own fault for not having checked the actual method
implementation.
I'm off defining my interfaces now...

All the best,

Martin

Thanks a lot for the quick replies, Jinyuan.

I checked WSDL2Java for the JUnit option you mentioned, but couldn't
find it.
As for the URL I call the web service with, it's a bit different from
the one you provided. I tried the following:
http://localhost/WSTest/services/SayHello2?method=hello&in0=Bla
and
http://localhost/WSTest/services/SayHello2?method=hello&in=Bla

Neither of this works.

I have also pasted the client code below. This only returns a null
value.

Cheers,

Martin
