Jim-
As you already know Visual Basic IDE is no longer supported by Microsoft I would strongly recommend you use supported axis downloads available at http://ws.apache.org/axis/java/building-axis.html If you have any questions dont hesitate to contact me offline,

Subject: NullPointerException vb6 client
I am using a vb6 client app which accesses a web service residing on a Apache Coyote/1.0 1b1 server
I used PocketSOAP WSDL Client Wizard to create a vb6 dll project from the wsdl which I then compiled and
reference with my client app.
I am receiving NullPointerException any time I make what I believe to be a valid request.
(However I do receive a defined FieldValidationException when I pass a bad arg i.e. a MAC with ":" rather than just hex digits
or any invalid mac value such as the last example below where I switched the order of args passed.)
Below is a tcpTrace of two requests/response.
Most information I have seen referring to NullPointerException has to do with the installation on the server such as
jdk version, classpath, etc...
The server I am testing against is a new 'live' installation so this also makes me wonder if it may have to do with the
server rather than my request.
However since I am receiving proper validation error it appears that the web service is functioning properly at least
to some degree and may be the way my request is formatted.
Any help I receive from the developers of the web service is sparse and slow. So any suggestions would be greatly
appreciated.
